As a first step,

Enable Change Tracking for the entity, custom Demo Entity in our case here.

Suppose we have 5 records created for Demo Entity.

As we are calling it for the first time DataVersion is set as empty.

We got all the 5 records as new or updated item.

Save the DataToken to be used while determining the changes and to be passed next time.

Now let us delete Record 1 and Record 2 and update Record 5 and run the code again this time passing the DataToken saved

As expected we get 3 changes.

Now suppose we create a new record name Record 6 and still use the old Data Token

As expected we got 4 changes here, which includes the new record 6 as new or update.

Point to remember here is if no version is passed the system will return all the records as new, and system will consider records that are within 90 days, if it is older than 90 days all the records will be returned.

If we have a new record created and deleted before we retrieved for the changes and the record didn’t exist at the time of retrieval, we will still get the record as deleted.

Sample Code

</p>
<p>EntityCollection newOrUpdatedEntityCollection = new EntityCollection();<br />
EntityReferenceCollection removeOrDeletedEntityRefCollection = new EntityReferenceCollection();</p>
<p>RetrieveEntityChangesRequest retrieveEntityChangeRequest = new RetrieveEntityChangesRequest();<br />
retrieveEntityChangeRequest.Columns = new ColumnSet();<br />
retrieveEntityChangeRequest.Columns.AddColumn("new_name");</p>
<p>// pass DataVersion<br />
retrieveEntityChangeRequest.DataVersion = "1018501!10/24/2016 12:31:46";</p>
<p>retrieveEntityChangeRequest.EntityName = "new_demoentity";<br />
retrieveEntityChangeRequest.PageInfo = new PagingInfo();</p>
<p>RetrieveEntityChangesResponse retrieveEntityChangesResponse = (RetrieveEntityChangesResponse)organizationProxy.Execute(retrieveEntityChangeRequest);</p>
<p>foreach (var entity in retrieveEntityChangesResponse.EntityChanges.Changes)<br />
{<br />
var dataToken = retrieveEntityChangesResponse.EntityChanges.DataToken;</p>
<p>if (entity.Type == ChangeType.NewOrUpdated)<br />
{<br />
newOrUpdatedEntityCollection.Entities.Add(((NewOrUpdatedItem)entity).NewOrUpdatedEntity);<br />
}<br />
else if (entity.Type == ChangeType.RemoveOrDeleted)<br />
{<br />
removeOrDeletedEntityRefCollection.Add(((RemovedOrDeletedItem)entity).RemovedItem);<br />
}<br />
}</p>

Before the updates that we have received for solution in CRM 2016 the only way to delete components from managed solution was to use Holding Solution.

The following post nicely explains this.

https://blogs.msdn.microsoft.com/devkeydet/2012/05/29/deleting-things-from-a-deployed-crm-2011-managed-solution-package/

Now let us see how we can do this in CRM 2016 without using Holding Solution.

Suppose below is our managed solution that includes 2 Action, 2 Entity, 2 SLA, 2 Workflow.

Entity 2 with two forms.

Entity 2 with 2 Views.

Entity 2 with two Fields.

Now import this solution as managed in destination org.

Now suppose we do not want following components in our Destination org – action 2, dashboard 2, Report 2, Security Role 2, Workflow 2 etc. along with View 2, Field 2 and Form 2 for Entity 2.

We remove some of the components and delete (field, form etc.) from our unmanaged solution (named Core Solution) which we had imported as Managed in our Destination Org.

Deleted View 2

Deleted Field 2

Now click on “Clone to Solution“. (This will increment the version number.)

Now import this updated solution to our destination organization, and select “Stage for Upgrade”

Click on “Apply Solution Upgrade”

This will remove the components from our destination org.
