Hi Peter
You need to apply all the transports into the QAS system which were moved to QAS system prior to the client copy , but which were not moved into PROD system ..
Simple way to find the list :
Login to PROD system and check the Import Queue
( All the transports which are in INIT Status there are the TR's that have moved into QAS but not into PROD )
You need to re-import them back into the QAS system
hope it helps
Thanks
Rishi
