• What is the cause and solution for SAP error message ON164 - Choose at most one object type ?

  The SAP error message ON164 ("Choose at most one object type") typically occurs in the context of object selection in SAP, particularly when working with transaction codes that involve object management, such as in the Object Navigator or when dealing with certain reports or functions that require the selection of specific object types.
