This User Interface allows you to map the extension base service data item and User Defined Screen extension service data item. In this User Interface, first the data item for the user defined screens service context segment fw_Context mapping is done followed by the in-segment that is the flow of data from the base to UDS which is followed by the header segment save and then the details grid save. Out segment that is flow of data from UDS to Base UI is not mandatory.During unmapping also, first the out segment is unmapped followed by the detail segment save unmapping, header segment save unmapping, in segment unmapping and finally fw_context unmapping.The execution sequence of the method is defined in this page
