Can Logical Model Changes be Sync'd with Model Source to a Physical Model after a Roll Up Transformation?
Answer: Not by design. Once a roll-up transformation is performed on a physical table, the underyling tables (sub-categories on the logical side) no longer exist in the physical model. Consequently logical model side changes cannot be sync'd to these tables.
If a synchronization with a logical model is needed, we recommend removing the table that the roll up transformation was run on from the physical model. Then re-sync with the logical model and perform the transformation again.
