Question:

I have a lot of free DSNBs in my TMC, can I use TMSXTEND to remove them?

Environment:

CA 1 12.6 and 14.0

Answer:

TMSXTEND can be used to remove DSNBs that have never been used at the end of the DSNB chain.  TMSBLDVR can be run to see how many can be removed.  If the DSNBs have been used, you would have to use the TMSSPLIT and TMSMERGE programs and build a new TMC with less DSNBs.
