• What is the cause and solution for SAP error message WRBA120 - You are not authorized for this transaction for supplier & or plant ?

  SAP Error Message:
  
  WRBA120 - You are not authorized for this transaction for supplier & or plant
  
  Cause:
  This error occurs because the user does not have the necessary authorization to perform the transaction for the specified supplier and/or plant. In SAP, authorizations are controlled via roles and profiles assigned to users, and these roles include specific authorization objects that restrict access based on organizational levels such as supplier/vendor and plant.
  Specifically, the error usually relates to missing or insufficient authorizations for the following authorization objects:
  
  M_BEST_BSA (Purchasing Document Type)
  M_LIFNR (Vendor)
  M_WERKS (Plant)
  M_EINK_FRG (Purchasing Document Release Authorization)
  Other related purchasing or vendor master data authorization objects
  
  If the user tries to access or process a transaction involving a supplier or plant for which they lack authorization, SAP throws this error.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to display the last failed authorization check.
  This will show which authorization object and field values caused the authorization failure.
  
  
  
  Review and Adjust Roles:
  
  Identify the roles assigned to the user via transaction SU01 or PFCG.
  Check the authorization objects related to purchasing and vendor master data in these roles.
  Ensure that the roles include the correct vendor numbers (LIFNR) and plants (WERKS) for which the user needs access.
  If necessary, extend the authorization values or create a new role with the required authorizations.
  
  
  
  Assign Correct Roles to User:
  
  After adjusting or creating the appropriate roles, assign them to the user.
  Have the user log off and log back in to refresh authorizations.
  
  
  
  Test the Transaction:
  
  Verify that the user can now perform the transaction without the authorization error.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SU53 – Display authorization check failure
  SU01 – User maintenance
  PFCG – Role maintenance
  ME21N / ME22N / ME23N – Purchase order transactions (common transactions where this error might appear)
  MK01 / MK02 / MK03 – Vendor master transactions
  
  
  
  Authorization Objects to Check:
  
  M_LIFNR – Vendor master authorization
  M_WERKS – Plant authorization
  M_BEST_BSA – Purchasing document type
  M_EINK_FRG – Purchasing document release authorization
  
  
  
  Notes:
  
  Always follow your organization's security policies when modifying authorizations.
  Avoid giving overly broad authorizations; restrict access to only necessary vendors and plants.
  If you are unsure about the required authorizations, consult with your SAP Security or Basis team.
  
  
  
  
  Summary:
  
  The WRBA120 error is an authorization issue related to supplier and/or plant access. The solution involves analyzing the failed authorization check (via SU53), adjusting user roles and authorizations accordingly, and ensuring the user has the correct permissions for the supplier and plant involved in the transaction.
