Customer has made changes to a Table that has been rolled up using the Roll-up Transform, but can’t import that change from the physical target model to a logical only source model, using the Sync with Model Source. Why?
This is by design, since the roll-up is done, so the Table does not exist in the physical only model. You have to remove Rolled-Up Transform Table and import the Tables over again, during the Sync with Model Source and do the Roll-up Transform again. That will allow the Logical Only Model to be updated with new objects.
