BCOS_CUST reported by field empty

Hi,

we use Solman 7.1.

I want to establish creating support messages in the satellite systems.

I configured table BCOS_CUST in satellite system correctly. RFC works.

I copied SMIN to ZMIN and adopted the role reported by. The I changed the access sequence in partner functions procedure, to "preceding document --> reporter --> current user",

The business partner are created via AI_SDK_USER_BP_GEN with the identification in the satellite system, as note: we use central user management.

The support message is successfully created and in the note SY-UNAME is filled correctly.

How can I resolve the problem?

Thanking you in anticipation

Best regards,

Christina
