To my understanding, DBFIND simply locates the head of chain pointer by looking in the specified master set. If the DBFIND is successful, it would appear that you have the automatic master entry that you need. What is your basis for thinking that the master entry is missing? Since the DBGET fails (and you don't say exactly how it fails -- crashes is kind of a broad term), I'd say the record pointer on the automatic master is not pointing to a valid record in the detail set. I don't know what tools you have, but basically, you need to unload (via serial access) the detail data sets that hang off that master and reload them to rebuild the master. Good luck!
