I can find the name of the program that triggered the trigger by "walking the stack." But I need to do the same thing when the trigger was "pulled" by a DDM user, who is identified as QUSER on the partition where the triggered physical file exists. What can I do to "walk the stack" on the partition that triggered the trigger through a DDM file? Is there an exit point on the source partition that I can register for DDM access to another partition? Or what? At trigger time on the target partition, can I return somehow to the source partition and have access to the stack? I'm stuck. Thanks, Ralph
