Usage Notes
When storing incoming WTORs, a search for code definitions for the message ID, WTORS, is first made in the entry for the subsystem that issued the WTOR.
If the subsystem itself cannot be found in the automation policy or the code definitions that are searched for are not found for the subsystem, they are searched for under the MVSESA entry. For subsystems such as IMS or NetView that have a permanent outstanding reply, you should specify the code definitions for the subsystem entries themselves instead of MVSESA. This improves performance by reducing searches within the automation policy.
