I have checked all business packages relating to SRM present in portal.

We are implementing SRM 7.0 EHP 3 and portal 7.4.

Please find attachment for detailed explanation about this error.

I have also shared a document that gives brief idea about this error.

Please suggest to solve this issue.

Awaiting for your response.

Thanks and regards,

Padmavati Iyer.
