Set this parameter to accept unprotected internal RFC-connections on an SNC-enabled AS ABAP server.
Set this parameter to accept unprotected RFC connections that originate from internal SAP systems and have internal destinations (see transaction SM59), even if you generally require SNC protection for RFC connections (snc/accept_insecure_rfc = 0).
This parameter is effective only if snc/accept_insecure_rfc = 0. Otherwise, the system accepts all RFC connections, both internal and external, regardless of this parameter’s setting.
1 (accept unprotected internal RFC connections)
snc/enable (activate SNC)
snc/accept_insecure_rfc (accept unprotected RFCs)
snc/r3int_rfc_secure (starting internal RFCs with SNC)
0 : Reject unprotected internal RFCs
1 : Accept unprotected internal RFCs
