The %NUMBER variable is defined in the DOCLIB member like below:
NUMBER = '111'
It works for the jobs that had been loaded originally, but is ignored for the inserted JOBs.
If used AH (or ADHOC) to insert the predefined JOB, the following error is issued:
ESPWSS2740W SYMBOL NUMBER NOT DEFINED
Working as designed.
Suggestion: move the variable definition to the ESP Proc instead of using DOCLIB.
