I have a custom Data Entity for the Service Order Table. My primary key is my ServiceOrderNumber field.
When I import a file with an existing ServiceOrderNumber it updates the record as expected.
However, if I want it to create a new record I can't use the 'Auto Generate' on my primary key as that would break the 'update'.
So, I decided to follow what had been done in the CustCustomerV3Entity.
I set my 'ServiceOrderNumber' 'Allow Edit' field properties on the Entity and Staging table to 'Yes'.
In looking through all the setup and code for the customer entity, this seems to be it. However, I still get:
The second error is a result of the first error and may not matter (I believe).
