DDBTGLM in release 15.0 generates a new 5005 KEY transaction.
It exists to expand the use of the 1000 ALTER transaction to the KEY entity-type.
DDUPDATE execution in CA Datacom/DB release 14.0, with an input of of a DDBTGLM executed in 15.0 will generate the following error:
DDFGUPG0168 TRANS NOT DEFINED TO DICTIONARY
The correction is to manually (or by other tools) remove cards 5005 from the input cards.
Modify the User Written Exit program shown in Appendix A of the batch User Guide to stop DDBTGLM from writing the 5005 transactions.
DDBTGLM does not have a "previous release" function.
