A user tried to force start a job for which they were the owner but the job was in a box which had a a different owner.
They did NOT have permissions for the box.
This resulted in error:
CAUAJM_E_10230 User:Mark does not have Execute (x) permission on job: 123
Workload Automation AE 11.x
This is working as designed, in order to start a job within a box the user must also have access to the box job. To work around the restriction one may execute the job as an exec super user, as they have access to all jobs (In NATIVE Security mode). Other options are to consider changing the owner of the box job to match the inner job's owner or move the inner job outside of the box.
