"I can’t run the Deferred Payment checks. I get a message on the menu ‘username AT WORKSTATION workstation IS CURRENTLY PRINTING DEFERRED CHECKS'":
This message will show when another user &/or workstation is running deferred payment checks and has not finished yet or was ended abnormally.
Determine if that user is currently running deferred payment checks. If they are running deferred payment checks then you will need to wait until they are finished. If they are not then you can run the following command to clear the data area:
CHGDTAARA DTAARA(DEFCHECKS *ALL) VALUE(' ')
(NOTE: Only run this if you are sure no other user is running deferred payment checks or you will risk losing the deferred payments.)
Rerun the deferred payment check option.
