Confirmation Release Rejected in ECS

Hi All,

We implemented ECS (SRM 5.0, Server 5.5).

PO is creating in EBP and replicating to ECC 6.0. but when we trying to create Confirmation in SRM side it says "Conformation 5000XXXXX Release Rejected.

I am able to create GR and IV in ECC side, but unable to create Confirmation in backend.

Did anyone face this problem?

Thanks,
