• What is the cause and solution for SAP error message VMP_MSG300 - You are not authorized to access Change Master information ?

  SAP Error Message:
  
  VMP_MSG300 You are not authorized to access Change Master information
  
  Cause:
  This error occurs because the user does not have the necessary authorization to access or change the "Change Master" information in the SAP system. The "Change Master" typically refers to master data related to vendor, material, or other business objects that require specific permissions to view or modify.
  In SAP, access to sensitive master data changes is controlled by authorization objects. If the user’s role or profile lacks the required authorization, the system will prevent access and display this error.
  
  Solution:
  
  
  Check User Authorizations:
  
  Identify the authorization object(s) controlling access to the Change Master data. Common authorization objects related to master data changes include:
  
  V_VBAK_VKO (Sales Document: Authorization for Sales Organizations)
  V_VBKA_VKO (Sales Document: Authorization for Sales Organizations)
  V_VBKA_AAT (Sales Document: Authorization for Activity Types)
  V_VBKA_VKO (Sales Document: Authorization for Sales Organizations)
  Or specific custom authorization objects related to the Change Master data in your system.
  
  
  
  
  
  Use SU53 to Analyze Authorization Check:
  
  Have the user reproduce the error.
  Immediately after, run transaction SU53 to display the last failed authorization check.
  This will show which authorization object and field values are missing.
  
  
  
  Adjust Roles/Profiles:
  
  Based on the SU53 output, update the user’s role(s) to include the missing authorizations.
  This is done in transaction PFCG by adding the required authorization objects and values.
  Ensure that the user has the necessary activity (e.g., Display, Change) for the relevant master data.
  
  
  
  Transport Changes:
  
  If changes are made in a development system, transport the updated roles to the production system following your change management process.
  
  
  
  Test Access:
  
  After role adjustment, have the user test the access again to confirm the issue is resolved.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SU53 – Display authorization check failure
  PFCG – Role maintenance
  SU01 – User maintenance (to check assigned roles)
  
  
  
  Authorization Objects:
  
  Check with your SAP security team or BASIS team for the exact authorization objects related to the Change Master data in your system, as these can be customized.
  
  
  
  Notes and Documentation:
  
  Review SAP Notes related to authorization issues for the specific module you are working in (e.g., MM, SD, FI).
  Consult SAP Help Portal or your internal documentation for master data authorization concepts.
  
  
  
  
  Summary:
  The error VMP_MSG300 indicates insufficient authorization to access or modify Change Master information. The solution involves identifying the missing authorization via SU53, updating the user’s roles in PFCG to include the necessary permissions, and then testing the access again. Coordination with your SAP security team is essential to ensure proper and secure role adjustments.
