Maintaining SAP Customer numbers - Solution Manager 7.1

Maintaining SAP Customer numbers

initiallly after installation of Solution Manager 7.1, to configure MO, S-user must be assigned.

however couldnt find SAP customer number tab in aisuser

during basic setup for customer numbers in spro, in the documentation I found that report AI_SC_GET_SAP_CUSTOMER_NUMBERS automatically fills V_AISAPCUSTNOS.

It didnt work out.

Also, is there any rfc need to be created manually as SM_SP_<customer no>, or it is automatically created,
couldnt find anything on that

can anyone help.
