• What is the cause and solution for SAP error message LM144 - You are not authorized to change reservations ?

  The SAP error message LM144, which states "You are not authorized to change reservations," typically occurs when a user attempts to modify a reservation in the SAP system but lacks the necessary authorization. This can happen in various modules, such as Materials Management (MM) or Warehouse Management (WM).
  Cause:
  
  Authorization Issues: The user does not have the required authorization object to change reservations. This is often due to missing roles or permissions assigned to the user profile.
  User Role Configuration: The roles assigned to the user may not include the necessary permissions for the specific transaction or action they are trying to perform.
  Transaction Code Restrictions: Certain transaction codes may have restrictions based on user roles, leading to this error when attempting to access them.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error. This will show you the last authorization check and help identify which authorization object is missing.
  Review the authorization logs to determine which specific permissions are lacking.
  
  
  
  Modify User Roles:
  
  Work with your SAP security team or system administrator to review and modify the user roles. Ensure that the user has the necessary authorizations for changing reservations.

  M_RESERV (Reservation: Authorization for Reservations)
  
  
  
  
  
  Testing:
  
  After adjustments are made to the user roles, have the user log out and log back in to ensure that the new authorizations take effect.
  Attempt to change the reservation again to verify that the issue is resolved.
  
  
  
  Documentation and Training:
