Send to SAP Authorization Error

Hi Gurus!

We are using SAP Solution Manager for incident management becuause of being VAR Partner.

Our customers open their message via Solution Manager and We are checking, approving or sending to sap this messages from CRMD_ORDER or AGS WORKCENTER.

I can set some customer's message as Send to SAP but for our 2 customers I can't send them to SAP and getting error "You do not have authorization to Send or Compare a notification".

I have lot's of role exclude SAP_ALL and SAP_NEW profile and can send to sap for other customers. I think it depends on Business Partner but I have little knowledge about BP.

Can you please help us!

Best regards
