Re: No authorization to log on as a Trusted System (L-RC=2 T-RC=0).

Hi

What are your sap systems versions ?

Did you grant S_RFC_TT auth obj ?

Best regards

1680501 - SMT1 SMT2 : No authorization for object S_ADMI_FCD

S_RFC_TT is a new authorization object introduced in SAP_BASIS 702 (and higher releases).
If at least one of the systems is running SAP_BASIS 702 (or higher), then there are two authorization objects involved - S_ADMI_FCD and S_RFC_TT.

1734607 - SM: Authorization object S_RFC_TT 7.02 and higher

With 7.02 a new authorization object has been introduced which is "s_rfc_tt". Have this object in your roles in both systems and assign it to all users who need to use these trusted rfcs.
