While refreshing billing due list on EP portal we are facing slowness issues. It's taking more than 10 minutes to refresh. We recorded trace for the user in the backend ECC system but in ECC process is completing within a second. Even SAP confirmed that there is no database issue in ECC.
We recently upgraded our NW version , ehp and sql Db also.
Can anyone help to solve this portal latency for perticulr tab only.
