FILE_IN is an ASCII file containing all input parameters for calling the function module PS_SYSTEM_IMPORT or PS_SYSTEM_EXPORT . The external project software creates FILE_IN. When you specify FILE_IN, all other parameters except FILE_OUT are ignored.

If you do not specify a FILE_IN, all parameters except SELECT_PARAMETERS and OBJECT_METHODS are optional, however, you must choose either ATTRIBUTE_LINES or ATTRIBUTES .
