Where are Return Code (RC) values that are listed in some of Spool ESF message statements?
For Example:
ESF765 JES-TO-ESF INTERFACE - ESF FILE WRITE FAILED, RC=OL, ...
To figure out these messages, you first need to note the failed request, which in this case is ESF WRITE, and then note the RC value, which is OL.
In the documentation, under topic Messages and Codes, search for 'ESFWRIT Return Codes'. Then follow down in the list
under ESFWRIT to find RC value OL to see:
OL--Write request rejected because the output limit was exceeded.
