With Qualifier for MANUAL JOBs, you can have multiple instances of the same JOB within an application.
CA WA ESP Edition 11.4 Z/OS
Note: NOPOST_UNTIL_READY option should be used, so when all instances run in sequence, they can be matched by different runs of the same JOB.
For example, MANUAL JOB M.1 and M.2 are not readied at same time, so JOB M on mainframe will post the readied one:
APPL AA NOPOST_UNTIL_READY
JOB M.1 MANUAL
JOB M.2 MANUAL
