We just upgraded our CA-Datacom environment and now when we try to join a "hold" file to a CA-Datacom table using 2 or more keys, we get the following error:

Jim,
As a general rule, even though WebFOCUS lets you do it, it is not a good idea to do a heterogeneous join as you are attempting.
One suggestions is to extract and hold the join keys from the hold file and use them in a WHERE fieldname IN FILE filename clause. There is a limit to the number of bytes for this file. Multiply the distinct number of key rows times the key length. If the number is less than 16,000 for relational then you are good to go and this technique will work for you.
We backed out the Datacom changes and everything worked again. We have since, re-applied the changes in test along with several patches and so far it appears to be working there as well. This case is closed. Thanks for the suggestions.
