Hello Samrat,
as I see in our test system this is a BW program for data extraction, I do not know, what this program is doing exactly and how it gets parameters. You can display the variant in SE38 for this program, what is configured in this variant, and if you can see already in the variant the parameters to read. You need to ask the BW team at SAP, why the program reads an obsolete parameter.
Regards,
Alwina
