  • What is the cause and solution for SAP error message WY141 - No authority to block suppliers ?

    SAP Error Message:
    WY141 - No authority to block suppliers


    Cause:

    This error occurs when a user tries to block a supplier (vendor) in SAP but does not have the necessary authorization to perform this action. Blocking a supplier is a sensitive operation that typically requires specific permissions because it affects procurement and payment processes.


    Explanation:

    • The system checks the user's authorizations when attempting to block a supplier.
    • If the user lacks the required authorization object or the correct activity within that object, the system issues the WY141 error.
    • The authorization object commonly involved is M_LIFNR_BEK (Vendor Master: Authorization for Blocking).
    • The user must have the appropriate activity (usually activity 02 = Change) for the vendor account group or company code.

    Solution:

    1. Check User Authorizations:

      • Use transaction SU53 immediately after the error occurs to display the missing authorization.
      • Alternatively, check the authorization trace with transaction ST01 to identify which authorization is missing.
    2. Grant Required Authorization:

      • The user needs authorization for the object M_LIFNR_BEK with the appropriate activity (e.g., 02 = Change).
      • The authorization should cover the relevant vendor account groups and company codes.
    3. Update Roles:

      • Update the user's role(s) in transaction PFCG to include the necessary authorization.
      • Transport the updated role to the relevant system if needed.
    4. Test:

      • After updating the authorization, test blocking a supplier again to confirm the issue is resolved.

    Related Information:

    • Authorization Object: M_LIFNR_BEK

      • Field: ACTVT (Activity) — typically 02 (Change) is required to block a supplier.
      • Fields: Vendor Account Group, Company Code, etc.
    • Transactions to check and maintain roles:

      • SU53 — Display authorization check failure.
      • ST01 — Authorization trace.
      • PFCG — Role maintenance.
    • Supplier Blocking Transactions:

      • XK05 — Block Vendor (Purchasing)
      • FK05 — Block Vendor (Accounting)
      • MK05 — Block Vendor (Purchasing)
    • Blocking a supplier can be done at different levels (purchasing, accounting, or both), and authorizations may differ accordingly.


    Summary:

    • Cause: User lacks authorization to block suppliers.
    • Solution: Grant authorization object M_LIFNR_BEK with activity 02 for the relevant vendor and company code.
    • Check: Use SU53 and ST01 to identify missing authorizations.
    • Maintain: Update user roles in PFCG accordingly.

    If you need further assistance, please provide the transaction code used and the user ID to help pinpoint the authorization issue.
