Hi There,
It won't work, although the source system ID is changed in RSBASIDOC, the source system dependent objects will not have been converted, I would suggest restarting the refresh using the correct procedure from note 886102. This is the only way to be confident of data consistency.
If you proceed with not doing this, then perhaps you could collect & tranport the source system dependent objects in a transport from another BW system and transport them to BW.
Personally speaking however, I would restart the refresh. There are too many unforseen variables to consider with your approach. I hope this helps.
Thanks,
Colm
