  The SAP error message LM143, which states "You are not authorized to create reservations," typically indicates that the user does not have the necessary authorization to perform the action of creating reservations in the system. This can occur in various SAP modules, particularly in materials management (MM) or warehouse management (WM).
  Cause:
  
  Authorization Issues: The user lacks the required authorization object to create reservations. This could be due to missing roles or permissions assigned to the user profile.

  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 authorizations are lacking.
