I am trying to do Checkout/in replica, all things goes very well. Unless deciding to create a new replica on the same gdb (Multiuser or File Gdb), I can create a replica with no errors and edits also, issue only appears when using synchronize tool 2nd time on same gdb it gives my the old Replica name with an error ERROR 000800 The value is not a member of DataBaseName.
to solve this issue I have to exit and reopen ArcGIS pro which is not logic, after the first Checkout/In replica I deleted all data (FC's) in the child DB also I make sure that no replicas are exist for the Parent & Child. Therefore I build a new Checkout replica.
