I had these same problems when first using commitment control

the resolution was to set the activation group to *CALLER in all the
programs of the application.

At first I had set all the programs to the same named activation group.
That worked OK.  But SQL coded SQL procedures do not know about named
activation groups. The solution was ACTGRP(*CALLER) on all RPG programs.
