CRM 2011/ 2013 Modify CreatedOn, CreatedBy, ModifiedOn, and ModifiedBy Using SDK C#

Often, we have requirements to import data from external data source to CRM and to keep the history, we should keep on eye for these following fields:

1. CreatedOn
2. CreatedBy,
3. ModifiedOn,
4. ModifiedBy

And we often think to update the database directly, yes, it is actually possible.

But, beside it is unsupported way, it is only applicable for those who implement CRM OnPremise, but in fact, we also have another CRM Online.

So, to update those fields using SDK, you can use these code lines:

TargetEntity["createdon"] = new DateTime(2011, 8, 8);
TargetEntity["overriddencreatedon"] = new DateTime(2011, 8, 8);
TargetEntity["createdby"] = new EntityReference("systemuser", new Guid("DDF26A49-4CBA-E311-9400-001CC4EECDD6"));
TargetEntity["modifiedby"] = new EntityReference("systemuser", new Guid("F1F26A49-4CBA-E311-9400-001CC4EECDD6"));
TargetEntity["modifiedon"] = new DateTime(2012, 8, 8);

Do not forget to change to your dynamic values for those assigned field values.

*You should use Late Bound since you cannot use Early Bound:



It will give error says “it is read only”;
And here is the result:



 

Hope it helps!
