  The SAP error message /SAPAPO/MD360 User & unknown (Enter an existing SAP user) typically occurs in the SAP Advanced Planning and Optimization (APO) module when a user tries to execute a transaction or function that requires a valid SAP user ID, but the system cannot recognize the provided user ID.
  Cause:
  
  Invalid User ID: The user ID entered does not exist in the SAP system.
  User Deactivation: The user ID may exist but is deactivated or locked.
  Authorization Issues: The user may not have the necessary authorizations to perform the action.
