RE: Impact Analysis

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.
