Have any thoughts or comments on the video? I would love to hear from you! I’m also keen to hear any ideas for future video content as well. Let me know by leaving a comment below or in the video above.

Working in-depth amidst the Sales entities (e.g. Product, Price List, Quote etc.) within Dynamics CRM/Dynamics 365 Customer Engagement (CRM/D365CE) can produce some unexpected complications. What you may think is simple to achieve on the outset, based on how other entities work within the system, often leads you in a completely different direction. A good rule of thumb is that any overtly complex customisations to these entities will mean having to get down and dirty with C#, VB.Net or even JScript. For example,¬†we’ve seen previously on the blog how,¬†with a bit of a developer expertise, it is possible to overhaul the entire pricing engine within the application to satisfy specific business requirements.¬†There is no way in which this can be modified directly through the application interface, which can lead to CRM deployments that make imaginative and complicated utilisation of features such as Workflows, Business Rules and other native features. Whilst there is nothing wrong with this approach per-say, the end result is often implementations that look messy when viewed cold and which become increasingly difficult to maintain in the long term. As always, there is a balance to be found, and any approach which makes prudent use of both application features and bespoke code is arguably the most desirous end goal for achieving certain business requirements within CRM/D365CE.

To prove my point around Sales entity “oddities”, a good illustration can be found when it comes to working with relationship field mappings and Product records. The most desirable feature at the disposal of CRM customisers is the ability to configure automated field mapping between Entities that have a one-to-many (1:N) relationship between them. What this means, in simple terms, is that when you create a many (N) record from the parent entity (1), you can automatically copy the field values to a matching field on the related entity. This can help to save data entry time when qualifying a¬†Lead to an¬†Opportunity, as all the important field data you need to continue working on the record will be there ready on the newly created¬†Opportunity record. Field mappings can be configured from the 1:N relationship setting window, via the¬†Mappings¬†button:

There are a few caveats to bear in mind – you can only map across fields that have the same underlying data type and you cannot map multiple source fields to the same target (it should be obvious why this is ūüôā ) – but on the whole, this is a handy application feature that those who are more accustomed to CRM development should always bear in the mind when working with CRM/D365CE.

Field mappings are, as indicated, a standard feature within CRM/D365CE Рbut when you inspect the field relationships between the Product and Quote Product entity, there is no option to configure mappings at all:

Upon closer inspection, many of the relationships between the¬†Product entity and others involved as part of the sales order process are missing the ability to configure field mappings. So, for example, if you have a requirement to map across the value of the¬†Description entity to a newly created¬†Quote Product¬†record, you would have to look at implementing a custom plugin to achieve your requirements. The main benefit of this route is that we have relatively unrestricted access to the record data we need as part of a plugin execution session and – in addition – we can piggyback onto the record creation process to add on our required field “in-flight” – i.e. whilst the record is being created. The code for achieving all of this is as follows:

using System;

using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;

namespace D365.BlogDemoAssets.Plugins
{
    public class PreQuoteProductCreate_GetProductAttributeValues : IPlugin
    {
        public void Execute(IServiceProvider serviceProvider)
        {
            //Obtain the execution context from the service provider.

            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

            //Get a reference to the Organization service.

            IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            IOrganizationService service = factory.CreateOrganizationService(context.UserId);

            //Extract the tracing service for use in debugging sandboxed plug-ins

            ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));

            tracingService.Trace("Tracing implemented successfully!");

            if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)

            {
                Entity qp = (Entity)context.InputParameters["Target"];

                //Only execute for non-write in Quote Product records

                EntityReference product = qp.GetAttributeValue<EntityReference>("productid");

                if (product != null)

                {

                    Entity p = RetrieveProductID(service, product.Id);
                    string desc = p.GetAttributeValue<string>("description");
                    tracingService.Trace("Product Description = " + desc);
                    qp.Attributes["description"] = desc;

                }

                else

                {
                    tracingService.Trace("Quote Product with record ID " + qp.GetAttributeValue<Guid>("quotedetailid").ToString() + " does not have an associated Product record, cancelling plugin execution.");
                    return;
                }
            }
        }

        public Entity RetrieveProductID(IOrganizationService service, Guid productID)
        {
            ColumnSet cs = new ColumnSet("description"); //Additional fields can be specified using a comma seperated list

            //Retrieve matching record

            return service.Retrieve("product", productID, cs);
        }
    }
}

They key thing to remember when registering your Plugin via the Plugin Registration Tool (steps which regular readers of the blog should have a good awareness of) is to ensure that the Event Pipeline Stage of Execution is set to Pre-operation. From there, the world is your oyster Рyou could look at returning additional fields from the Product entity to update on your Quote Product record or you could even look at utilising the same plugin for the Order Product and Invoice Product entities (both of these entities also have Description field, so the above code should work on these entities as well).

It’s a real shame that Field Mappings are not available to streamline the population of record data from the Product entity; or the fact that there is no way to utilise features such as Workflows to give you an alternate way of achieving the requirement exemplified in this post. This scenario is another good reason why you should always strive to be a Dynamics 365 Swiss Army Knife, ensuring that you have a good awareness of periphery technology areas that can aid you greatly in mapping business requirements to CRM/D365CE.

In last week’s post, we took a look at how a custom Workflow activity can be implemented within Dynamics CRM/Dynamics 365 for Customer Engagement to obtain the name of the user who triggered the workflow. It may be useful to retrieve this information for a variety of different reasons, such as debugging, logging user activity or to automate the population of key record information. I mentioned in the post the “treasure trove” of information that the IWorkflowContext interface exposes to developers. Custom Workflow activities are not unique in having execution-specific information exposable, with an equivalent interface at our disposal when working with plug-ins. No prizes for guessing its name – the IPluginExecutionContext.

When comparing both interfaces, some comfort can be found in that they share almost identical properties, thereby allowing us to replicate the functionality demonstrated in last weeks post as Post-Execution Create step for the Lead entity. The order of work for this is virtually the same:

  1. Develop a plug-in C# class file that retrieves the User ID of the account that has triggered the plugin.
  2. Add supplementary logic to the above class file to retrieve the Display Name of the User.
  3. Deploy the compiled .dll file into the application via the Plug-in Registration Tool, adding on the appropriate execution step.

The emphasis on this approach, as will be demonstrated, is much more focused towards working outside of the application; something you may not necessarily be comfortable with. Nevertheless, I hope that the remaining sections will provide enough detail to enable you to replicate within your own environment.

Developing the Class File

As before, you’ll need to have ready access to a Visual Studio C# Class file project and the Dynamics 365 SDK. You’ll also need to ensure that your project has a Reference added to the Microsoft.Xrm.Sdk.dll. Create a new¬†Class¬†file and copy and paste the following code into the window:

using System;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;

namespace D365.BlogDemoAssets.Plugins
{
    public class PostLeadCreate_GetInitiatingUserExample : IPlugin
    {
        public void Execute(IServiceProvider serviceProvider)
        {
            // Obtain the execution context from the service provider.

            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

            // Obtain the organization service reference.
            IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

            // The InputParameters collection contains all the data passed in the message request.
            if (context.InputParameters.Contains("Target") &&
                context.InputParameters["Target"] is Entity)

            {
                Entity lead = (Entity)context.InputParameters["Target"];

                //Use the Context to obtain the Guid of the user who triggered the plugin - this is the only piece of information exposed.
      
                Guid user = context.InitiatingUserId;

                //Then, use GetUserDisplayCustom method to retrieve the fullname attribute value for the record.

                string displayName = GetUserDisplayName(user, service);

                //Build out the note record with the required field values: Title, Regarding and Description field

                Entity note = new Entity("annotation");
                note["subject"] = "Test Note";
                note["objectid"] = new EntityReference("lead", lead.Id);
                note["notetext"] = @"This is a test note populated with the name of the user who triggered the Post Create plugin on the Lead entity:" + Environment.NewLine + Environment.NewLine + "Executing User: " + displayName;

                //Finally, create the record using the IOrganizationService reference

                service.Create(note);
            }
        }
    }
}

Note also that you will need to rename the namespace value to match against the name of your project.

To explain, the code replicates the same functionality developed as part of the Workflow on last week’s post – namely, create a Note¬†related to a newly created Lead record and populate it with the Display Name of the User who has triggered the plugin.

Retrieving the User’s Display Name

After copying the above code snippet into your project, you may notice a squiggly red line on the following method call:

The GetUserDisplayName is a custom method that needs to be added in manually and is the only way in which we can retrieve the Display Name of the user, which is not returned as part of the IPluginExecutionContext. We, therefore, need to query the User (systemuser) entity to return the Full Name (fullname) field, which we can then use to populate our newly create Note record. We use a custom method to return this value, which is provided below and should be placed after the last 2 curly braces after the Execute method, but before the final 2 closing braces:

private string GetUserDisplayName(Guid userID, IOrganizationService service)
    {
        Entity user = service.Retrieve("systemuser", userID, new ColumnSet("fullname"));
        return user.GetAttributeValue<string>("fullname");
    }

Deploy to the application using the Plug-in Registration Tool

The steps involved in this do not differ greatly from what was demonstrated in last week’s post, so I won’t repeat myself ūüôā The only thing you need to make sure you do after you have registered the plug-in is to configure the plug-in Step. Without this, your plug-in will not execute. Right-click your newly deployed plug-in on the main window of the Registration Tool and select¬†Register New Step:

On the form that appears, populate the fields/values indicated below:

  • Message:¬†Create
  • Primary Entity: Lead
  • Run in User’s Context: Calling User
  • Event Pipeline Stage of Execution: Post-Operation

The window should look similar to the below if populated correctly. If so, then you can click Register New Step to update the application:

All that remains is to perform a quick test within the application by creating a new Lead record. After saving, we can then verify that the plug-in has created the Note record as intended:

Having compared both solutions to achieve the same purpose, is there a recommended approach to take?

The examples shown in the past two blog posts indicate excellently how solutions to specific scenarios within the application can be achieved via differing ways. As clearly evidenced, one could argue that there is a code-heavy (plug-in) and a light-touch coding (custom Workflow assembly) option available, depending on how comfortable you are with working with the SDK. Plug-ins are a natural choice if you are confident working solely within Visual Studio or have a requirement to perform additional business logic as part of your requirements. This could range from complex record retrieval operations within the application or even an external integration piece involving specific and highly tailored code. The Workflow path clearly favours those of us who prefer to work within the application in a supported manner and, in this particular example, can make certain tasks easier to accomplish. As we have seen, the act of retrieving the Display Name of a user is greatly simplified when we go down the Workflow route. Custom Workflow assemblies also offer greater portability and reusability, meaning that you can tailor logic that can be applied to multiple different scenarios in the future. Code reusability is one of the key drivers in many organisations these days, and the use of custom Workflow assemblies neatly fits into this ethos.

These are perhaps a few considerations that you should make when choosing the option that fits the needs of your particular requirement, but it could be that the way you feel most comfortable with ultimately wins the day – so long as this does not compromise the organisation as a consequence, then this is an acceptable stance to take. Hopefully, this short series of posts have demonstrated the versatility of the application and the ability to approach challenges with equally acceptable pathways for resolution.

It’s sometimes useful to determine the name of the user account that executes a Workflow within Dynamics CRM/Dynamics 365 for Customer Engagement (CRM/D365CE). What can make this a somewhat fiendish task to accomplish is the default behaviour within the application, which exposes very little contextual information each time a Workflow is triggered. Take, for example, the following simplistic Workflow which creates an associated¬†Note¬†record whenever a new¬†Lead record is created:

The Note record is set to be populated with the default values available to us regarding the Workflow execution session –¬†Activity Count, Activity Count including Process¬†and¬†Execution Time:

We can verify that this Workflow works Рand view the exact values of these details Рby creating a new Lead record and refreshing the record page:

The¬†Execution Time¬†field is somewhat useful, but the¬†Activity Count¬†&¬†Activity Count including Process¬†values¬†relate to Workflow execution sessions and are only arguably useful for diagnostic review – not something that end users of the application will generally be interested in ūüôā

Going back to the opening sentence of this post, if we were wanting to develop this example further to include the Name of the user who executed the Workflow in the note, we would have to look at deploying a Custom Workflow Assembly to extract the information out. The IWorkflowContext Interface is a veritable treasure trove of information that can be exposed to developers to retrieve not just the name of the user who triggers a Workflow, but the time when the corresponding system job was created, the Business Unit it is being executed within and information to determine whether the Workflow was triggered by a parent. There are three steps involved in deploying out custom code into the application for utilisation in this manner:

  1. Develop a CodeActivity C# class file that performs the desired functionality.
  2. Deploy the compiled .dll file into the application via the Plugin Registration Tool.
  3. Modify the existing Workflow to include a step that accesses the custom Workflow Activity.

All of these steps will require ready access to Visual Studio, a C# class plugin project (either a new one or existing) and the CRM SDK that corresponds to your version for the application.

Developing the Class File

To begin with, make sure your project includes References to the following Frameworks:

  • System.Activities
  • Microsoft.Xrm.Sdk
  • Microsoft.Xrm.Sdk.Workflow

Add a new Class (.cs) file to your project and copy & paste the below code, overwriting any existing code in the window. Be sure to update the namespace value to reflect your project name:

using System.Activities;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Workflow;

namespace D365.Demo.Plugins
{
    public class GetWorkflowInitiatingUser : CodeActivity
    {
        protected override void Execute(CodeActivityContext executionContext)
        {
            IWorkflowContext workflowContext = executionContext.GetExtension<IWorkflowContext>();
            CurrentUser.Set(executionContext, new EntityReference("systemuser", workflowContext.InitiatingUserId));
        }

        [Output("Current User")]
        [ReferenceTarget("systemuser")]
        public OutArgument<EntityReference> CurrentUser { get; set; }
    }
}

Right-click your project and select¬†Build. Verify that no errors are generated and, if so, then that’s the first step done and dusted ūüôā

Deploy to CRM/D365CE

Open up the Plugin Registration Tool and connect to your desired instance. If you are deploying an existing, updated plugin class, then right-click it on the list of Registered Plugins & Custom Workflow Activities and click Update; otherwise, select Register -> Register New Assembly. The same window opens in any event. Load the newly built assembly from your project (can be located in the \bin\Debug\ folder by default) and ensure the Workflow Activity entry is ticked before selecting Register Selected Plugins:

After registration, the Workflow Activity becomes available for use within the application; so time to return to the Workflow we created earlier!

Adding the Custom Workflow Activity to a Process

By deactivating the Workflow Default Process Values Example Workflow and selecting Add Step, we can verify that the Custom Workflow Assembly is available for use:

Select the above, making sure first of all that the option Insert Before Step is toggled (to ensure it appears before the already configured Create Note for Lead step). It should look similar to the below if done correctly:

Now, when we go and edit the Create Note for Lead step, we will see a new option under Local Values which, when selected, bring up a whole range of different fields that correspond to fields from the User Entity. Modify the text within the Note to retrieve the Full Name value and save it onto the Note record, as indicated below:

After saving and reactivating the Workflow, we can verify its working by again creating a new Lead record and refreshing to review the Note text:

All working as expected!

The example shown in this post has very limited usefulness in a practical business scenario, but could be useful in different circumstances:

  • If your Workflow contains branching logic, then you can test to see if a Workflow has executed by a specific user and then perform bespoke logic based on this value.
  • Records can be assigned to other users/teams, based on who has triggered the Workflow.
  • User activity could be recorded in a separate entity for benchmarking/monitoring purposes.

It’s useful to know as well that the same kind of functionality can also be deployed when working with plugins as well in the application. We will take a look at how this works as part of next week’s blog post.
