Hello Experts,

Currently we are in SRM 7.02 implemenation: we are facing below problem while creating RFx response with popup screen.

                         "An error occurred in the PD Layer transaction terminated"

For this we have checked below

2. We have assigned SAP_ALL role to bidder also ----> Facing same issue

3. Check Number ranges ---> everything is fine.
