If you have + signs next to the jobs in WRKACTJOB then your menu system is starting group jobs. You will probably need to change the adopted authority on the group job initial program. You can find this in the source (if you have it) – look for the commands TFRGRPJOB & CHGGRPA. If you don’t have the source, you may be able to find the group job initial program by looking at the program stack of the group job, or the joblog of the group job.
Hope this helps,
