• What is the cause and solution for SAP error message WP728 - You are not authorized to change sales data ?

  SAP Error Message:
  
  WP728 - You are not authorized to change sales data
  
  Cause:
  The error WP728 occurs when a user attempts to change sales data (such as sales documents, sales orders, quotations, contracts, etc.) but does not have the necessary authorization to perform this action. This is typically due to missing or insufficient authorization objects related to sales and distribution (SD) module in the user's role/profile.
  
  Explanation:
  
  SAP controls access to business data through authorization objects.
  For sales data changes, the relevant authorization objects (e.g., V_VBAK_VKO for sales document authorization, V_VBKA_VKO for sales document header, V_VBPA_VKO for partner data, etc.) must be assigned with appropriate activity (change = activity 02).
  If the user lacks these authorizations, SAP prevents the change and throws WP728.
  
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to display the last failed authorization check.
  Identify which authorization object and field values are missing or insufficient.
  
  
  
  Review and Adjust Roles:
  
  Check the roles assigned to the user in transaction PFCG.
  Ensure the roles include the necessary authorization objects for sales data change.
  Specifically, verify authorizations for:
  
  Sales document types (VBAK-VTWEG, VBAK-VKORG, VBAK-VTWEG)
  Activities (02 = Change)
  Sales organization, distribution channel, division, etc.
  
  
  
  
  
  Update Authorization Profiles:
  
  Add or modify the authorization objects in the user's role/profile to include the required sales data change permissions.
  Transport the changes if necessary.
  
  
  
  Test:
  
  After updating authorizations, have the user try again to change the sales data.
  Use SU53 again if the error persists.
  
  
  
  
  Related Information:
  
  
  Authorization Objects Commonly Involved:
  
  V_VBAK_VKO – Sales Document: Authorization for Sales Organization, Distribution Channel, Division
  V_VBKA_VKO – Sales Document Header Authorization
  V_VBPA_VKO – Sales Document Partner Authorization
  V_VBEP_VKO – Sales Document Item Authorization
  V_VBFA_VKO – Document Flow Authorization
  
  
  
  Transactions to Check:
  
  SU53 – Display last authorization check failure
  PFCG – Role maintenance
  VA02 – Change Sales Order (where error might occur)
  
  
  
  Notes:
  
  Sometimes, the error can also occur if the sales document is locked or in a status that does not allow changes.
  Check if the document is locked by another user or process.
  Check if the document status allows changes.
  
  
  
  
  Summary:
  
  Cause: Missing/change authorization for sales data.
  Solution: Assign/change appropriate authorizations in user roles.
  Check: Use SU53 to identify missing authorizations, adjust roles in PFCG, and test again.
