Maintaining the System ACL on the SAP Application Server


In addition to being able to identify its communication partner using the SNC layer, the application server uses a system access control list (ACL) to make sure that it is communicating with the correct component.


  1. Maintain the SNC system access control list (table SNCSYSACL, view VSNCSYSACL, type=E). For example, use the table maintenance transaction SM30. Note the following:
    • Enter the IRC Server’s SNC name in the SNC name field.
    • Make sure you enter the server’s SNC name and not the Distinguished Name. The server’s SNC name is the Distinguished Name prefixed with p:
      • The System ID field is optional.
      • Activate Entry for RFC activated.
      • The other entries are optional.
  2. Save the data.
