  • What is the cause and solution for SAP error message /IWNGW/CM_HUB018 - RFC Error: User misses authorization object ?

    The SAP error message /IWNGW/CM_HUB018 RFC Error: User misses authorization object typically indicates that the user attempting to perform an operation does not have the necessary authorizations to execute the requested action. This error is often encountered in the context of Remote Function Calls (RFC) when the user lacks specific authorization objects required for the operation.

    Cause:

    1. Missing Authorization Object: The user does not have the required authorization object assigned in their user profile. This could be due to a lack of roles or profiles that include the necessary authorizations.
    2. Role Assignment: The roles assigned to the user may not include the necessary permissions for the specific transaction or function module being called.
    3. Profile Issues: The user profile may not be updated or may have been incorrectly configured, leading to missing authorizations.

    Solution:

    1. Check User Authorizations:

      • Use transaction SU01 to check the user’s authorizations.
      • Review the roles assigned to the user and ensure that they include the necessary authorization objects.
    2. Identify Required Authorization Objects:

      • Determine which authorization objects are required for the operation that is failing. This can often be found in the documentation for the specific transaction or function module.
      • You can also use transaction SU53 immediately after the error occurs to see which authorization check failed.
    3. Assign Missing Authorizations:

      • If you identify that the user is missing specific authorization objects, you can either:
        • Modify existing roles to include the necessary authorizations.
        • Create a new role that includes the required authorizations and assign it to the user.
    4. Consult with Security Team:

      • If you do not have the necessary permissions to modify roles or authorizations, consult with your SAP security team or administrator to resolve the issue.
    5. Testing:

      • After making changes to the user’s authorizations, have the user log out and log back in to ensure that the changes take effect.
      • Test the operation again to confirm that the error has been resolved.

    Related Information:

    • Authorization Objects: In SAP, authorization objects are used to control access to various transactions and functions. Each object can have multiple fields that define the specific permissions required.
    • Transaction Codes:
      • SU01: User Maintenance
      • PFCG: Role Maintenance
      • SU53: Display Authorization Check
    • Documentation: Refer to SAP Help documentation for detailed information on authorization management and troubleshooting authorization issues.
