Which process(es) update gl_code_combination_v with end dates on combos?

We are seeing end dates appear on combos that we did not intend. Our business practice is to use enable/disable, not effective dates. However, in reviewing data in gl_code_combinations_v we find several records with end dates. The record history shows users that do not have update rights in GL.  One of those is our batch processing user id so I suspect these records are being updated by one or more processes. I need to identify those to determine how to either prevent or embrace this functionality.  Thank you.
