display screen in a program, but not used when program called from batch

I've written an RPGIV program that uses a display file to get information 
if the information is missing from a record.

In one circumstance I wish to schedule the job to run in batch at night. I 
have already ensured the information is not missing, so the display file 
will not be needed.   However the batch job fails anyway.

Is that what is supposed to happen, or is there another error I am not 
finding?

Is there a way to resolve this issue without writing a second identical 
program sans display?

Thank you for your ideas, they are always welcome.
