  Error Message
  WSUBST104: Not authorized to display purchase order &1 &2
  
  &1 = Purchase Order Number
  &2 = Additional information (often the document type or related info)
  
  
  Cause
  This error occurs because the user attempting to display the purchase order does not have the necessary authorization to view the specified purchase order document.
  In SAP, access to purchase orders is controlled by authorization objects, typically related to purchasing documents. If the user’s roles or profiles do not include the required authorizations, the system will prevent access and show this error.
  Common reasons include:
  
  Missing or insufficient authorization for the purchasing document type.
  Authorization object M_BEST_BSA (Purchasing Document Type) not assigned or missing the relevant document type.
  Authorization object M_BEST_EKG (Purchasing Document Authorization Group) missing or not matching the document’s authorization group.
  User role does not include the necessary activity (e.g., display, change) for purchase orders.
  Authorization group assigned to the purchase order restricts access.
  
  
  Relevant Authorization Objects
  
  M_BEST_BSA: Authorization for purchasing document types.
  M_BEST_EKG: Authorization for purchasing document authorization groups.
  M_BEST_WRK: Authorization for purchasing document plant.
  M_BEST_BSA: Controls which purchasing document types a user can access.
  M_BEST_EKG: Controls access based on authorization groups assigned to purchase orders.
  
  
  Solution
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to check which authorization check failed.
  Alternatively, use transaction ST01 (Authorization Trace) to trace the authorization check.
  
  
  
  Verify Purchase Order Authorization Group:
  
  Check if the purchase order has an authorization group assigned (field EKGRP in the purchase order header).
  Ensure the user has authorization for this group in their roles.
  
  
  
  Adjust User Roles/Profiles:
  
  Add or adjust the user’s roles to include the necessary authorizations for:
  
  The purchasing document type (M_BEST_BSA).
  The authorization group (M_BEST_EKG).
  The plant or purchasing organization if relevant (M_BEST_WRK).
  
  
  Ensure the user has the Display (activity 03) authorization for purchase orders.
  
  
  
  Check Purchase Order Document Type:
  
  Confirm the document type of the purchase order and ensure the user has authorization for that document type.
  
  
  
  Transport or Assign Correct Roles:
  
  If roles need to be created or modified, coordinate with your SAP Security team.
  After role changes, have the user log off and log back in to refresh authorizations.
  
  
  
  
  Additional Information
  
  This error is common in environments with strict authorization controls on purchasing documents.
  Authorization groups are often used to restrict access to sensitive purchase orders.
  If the purchase order is created with an authorization group, users must have explicit authorization for that group.
  Sometimes, the error can also occur if the purchase order is locked or in a status that restricts display, but this is less common.
