Raising OSS through Solman after SP15

Dear All,

We have recently upgarded solman to SP15.After this,when we raise a OSS through solman,we get the following error.

-

The system could not find your SAP customer notification system user

Message no. DNO150

Diagnosis

The parameter SAPNETUSID that is required for communication with SAP is not maintained in your user master record.

-

We also found the note:1090535,but this note is already delivered with SP15.

One difference we found after sp15 is in AISUSER there is a addition column called SAP Customer Number.I am not able to add a new customer number.

Waiting for your inputs.

Regards,

Avinash.
