3525721 - Fields missing in the XML File or How to add fields to the Output form

Few Standard fields are not appearing in the XML file.

1. Generate a Purchase Order.
2. Export the Purchase Order details to an XML file.
3. Observe that the standard field is missing in the XML file.

In the standard form, only print fields that are included in the respective data source shall be visible.

For example Purchase order data source is PO's FDP_EF_PURCHASE_ORDER. 

To include a field that is not available in the data source the standard data source can be extended.

To fill the custom field automatically when creating the purchase order the BADI's can be used:
MM_PUR_S4_PO_MODIFY_HEADER or MM_PUR_S4_PO_MODIFY_ITEM.

There are BADI's MMPUR_PO_OUTPUT_HEADER_EXT and MMPUR_PO_OUTPUT_ITEM_EXT which allows to fill data in the form after save when the output is generated.
