Business Partner XXX cannot be the reporter

Hello,

When Message is raised using transaction NOTIF_CREATE. even though we have given SAP_SUPPDESK_create authorisation to user and also sap_all

when we try to save the message. we get a error message "Business Partner XXX cannot be the reporter"

We are using SPS17... work center is working fine.. except few hickups which is mentioned in my previous posts.

Regards,

Shyam.
