Hi Krishnendu
Please observe that the space SAP ERP Manufacturing - Production Planning (SAP PP) is specific for issues related to the component PP.
I understand that you are a PP consultant, but this is a generic question and you will get more answers if you open the thread in the correct space.
A quick search points that threads with similar questions were opened on the space ABAP Development, therefore, I'm moving this thread to this space:
How to transport variants and scheduled background jobs
Transporting job from one server to another
Copy Program Variant from a system to another
