Dear Vinita,
Sorry for the delay in my reply.
I have already checked those SAP notes.
I am able to assign the contract to Limit SC and i have assigned supplier manually as suggested by Ricardo.
Now i have an issue where contract details are not getting reflected in PO.
I am looking for scenario where i could create a Limit SC with contract, then PO should be created in ECC which should contain the contract number. And release value of the contract must be updated with the value of PO.
Thank you
Muzamil
