Output file being used where is it being used is it going to some downstream systems needs to be identified.
Check the copybook for the fillers if it can be reused. if not then adding the new fields needs to be checked to see what all procs or jobs use it and LRECL needs to be changed.
The impacted jobs where this input file needs to be added.
Where this source program is being used what all jobs are using it.
Where the copybook is used needs to be recompiled.

First of all - it needs to be understood what the program is used for. Questions like

i) why the new file is being introduced to the program?

ii) adding extra two columns to the output file - will that impact the other programs which might be using that file?

ii) is there any user interface linked to the program?

iii) if yes, how frequently that interface is used and will there be any change in that interface?

iv) if program is used for any reporting etc, will there by any changes to the hard copy reports, spool settings etc.

v) the two extra columns - can they be accommodated with the existing LRECL of the output file or will that need to be reconsidered.

should be answered and the changes should be considered.
