• What is the cause and solution for SAP error message 5A454 - Object type '*' is not allowed ?

  The SAP error message "5A454 Object type '' is not allowed" typically occurs when there is an attempt to use a wildcard character () in a context where it is not permitted. This can happen in various scenarios, such as when trying to specify object types in authorization checks, transport requests, or other configurations where specific object types are expected.
  Cause:
  
  Wildcard Usage: The error is primarily caused by the use of the wildcard character () in a field that does not support it. For example, if you are trying to filter or search for object types in a transaction or report and you use '', the system may not allow it.

  Check Authorizations: If the error is related to authorizations, ensure that the user has the necessary permissions for the specific object types being accessed.
