ReleaseAllCauseThe dictionary field 'base_update_set' is inactive for the table 'sys_update_set'. This might be inactive in both source and target instances. ResolutionPlease turn these dictionary records to 'active' in both source and target instances and the retrieval process of the batch update set should work as expected. In case if you do not want to make the 'base_update_set' active, try export and import XML of the update set and it should work.
