This process corresponds to the business process scenario: Variant 1: Space Management for Information Only.
1. Specify the layout module you want to examine.
2. Function module document_show_direct calls the external space management program.
3. The space management program executes and displays the planogram relevant for that layout module. If more than one planogram exists, you can select the one you want. If there is no corresponding planogram, then function module ws_execute simply calls up the space management program without displaying a specific planogram.
Because this variant assumes no data communication between the SAP system and the space management program, all you can do here is examine the data.
