Assignments are included in the merge procedure under the following conditions:
You have enabled the Synchronize assignments check box on the Select conflict resolution wizard page.
If you selected both the object and the assigned model in the source database, the assignment relationship will be created automatically in the target database.
If you specify an assignment level, assignments will be included even if the assigned models have not explicitly been selected for the merge procedure (Select merge options wizard page).
New assignment
An assignment in the source database is created in the target database if an identical assignment does not exist in the target database.
Same assignments
If identical assignments exist in the source and target databases, conflict resolution is performed based on the settings for objects (Select conflict resolution wizard page).
