• What is the cause and solution for SAP error message ME147 - & requisition(s) not changed due to lack of authorization ?

  The SAP error message ME147 indicates that a user does not have the necessary authorization to change a purchase requisition. This error typically arises when a user attempts to modify a requisition but lacks the required permissions defined in the authorization profiles.
  Cause:
  
  Lack of Authorization: The user does not have the necessary authorization object for changing purchase requisitions. This could be due to missing roles or authorizations in their user profile.
  Authorization Object: The relevant authorization object for purchase requisitions is usually M_BEST_BSA (for purchase requisition) and M_BEST_EKO (for purchasing documents).
  Document Status: The requisition may be in a status that does not allow changes (e.g., if it has been converted to a purchase order).
  Organizational Level Restrictions: The user may not have access to the specific organizational units (e.g., plant, purchasing group) associated with the requisition.
  
  Solution:
  
  
  Check User Authorizations:
  
  Verify the user's roles and authorizations in the SAP system. This can be done by using transaction code SU53 immediately after the error occurs to see which authorization check failed.
  Consult with your SAP security team to ensure that the user has the necessary roles assigned.
  
  
  
  Modify User Roles:
  
  If the user lacks the required authorizations, the SAP security team should update the user's roles to include the necessary authorizations for changing purchase requisitions.
  
  
  
  Review Document Status:
  
  Ensure that the purchase requisition is in a status that allows changes. If it has been converted to a purchase order, the requisition may no longer be editable.
  
  
  
  Organizational Level Access:
  
  Confirm that the user has access to the relevant organizational units associated with the requisition. This may involve checking the user's assigned plants, purchasing groups, or other relevant organizational data.
  
  
  
  Training and Documentation:
  
  Provide training or documentation to users on how to properly manage purchase requisitions and understand the authorization requirements.
