• What is the cause and solution for SAP error message CNV_OR_PS108 - Error - missing RFC authorizations ?

  The SAP error message CNV_OR_PS108 indicates that there are missing Remote Function Call (RFC) authorizations for a user when trying to execute a specific operation, typically related to data migration or conversion processes. This error is often encountered during the execution of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  The error occurs due to insufficient authorizations for the user executing the operation. This can happen if:
  
  The user does not have the necessary roles assigned that include the required RFC authorizations.
  The RFC destination being used does not have the correct authorizations set up for the user.
  There are restrictions in place that prevent the user from executing certain functions remotely.
  
  Solution:
  To resolve the CNV_OR_PS108 error, follow these steps:
  
  
  Check User Roles and Authorizations:
  
  Verify that the user has the appropriate roles assigned. This can be done by checking the user’s profile in transaction SU01.
  Ensure that the roles include the necessary authorizations for the RFC functions being called.
  
  
  
  Review RFC Destination:
  
  Check the RFC destination being used (transaction SM59). Ensure that the destination is correctly configured and that the user has the necessary authorizations for that destination.
  Test the RFC connection to ensure it is working properly.
  
  
  
  Assign Missing Authorizations:
  
  If specific authorizations are missing, you may need to work with your SAP security team to assign the required authorizations. Common authorizations that may be needed include:
  
  S_RFC (RFC authorization)
  S_TCODE (Transaction code authorization)
  Any other specific authorizations related to the functions being executed.
  
  
  
  
  
  Check for Authorization Objects:
  
  Use transaction SU53 immediately after the error occurs to see which authorizations were checked and failed. This can provide insight into what specific authorizations are missing.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration or conversion tool you are using to identify any additional authorization requirements.
  
  
  
  Testing:
  
  After making changes to roles or authorizations, test the operation again to see if the error persists.
