• What is the cause and solution for SAP error message SIG254 - You are not authorized to execute a digital signature ?

  The SAP error message SIG254, which states "You are not authorized to execute a digital signature," typically occurs when a user attempts to perform an action that requires a digital signature but does not have the necessary authorizations.
  Cause:
