Hi Developers,
I have been wondering about this issue for a week so far, I wouldn't have reached out for your help if it was not really needed.
Last week I started developing CRM Dynamics 365 online. I was asked to create an auto-generated field in Work Order entity that sets its value based on its service account. I have decided to do this through plugin development and I have successfully registered the plugin in the Pre-Operation of Create Step and I was able to debug my code and do the business logic correctly Backend wise. What I have found weird while debugging my code was
the new created field was not available in the entity.Attributes Call.
I neglected that as I thought since it doesn't contain any data yet maybe it is not available in the attributes, so I used entity.Attributes.add. But even though the value was set in the WO create Form after saving. I have been searching for what could be causing such an issue for about a week and your help will be much appreciated. Thank You.
