  The SAP error message L3638, which indicates "Insufficient authorization," typically occurs when a user attempts to perform an action or access a transaction for which they do not have the necessary permissions. This can happen in various modules, including logistics, finance, and others, depending on the specific transaction being executed.
  Cause:
  
  Missing Authorization Object: The user’s role may not include the necessary authorization objects required for the transaction.

  Authorization Profile: The authorization profile assigned to the user may not cover the required authorizations.
