I have retired my documentation tools.
The reason is that they used an old form for documentation and SAP PI/PO did no longer support the use of XIM files. It was therefore not as much the tool was used anymore.
I have created a short guide to how you can export your mappings to an Excel sheet with NWDS. I’m not to found of the layout of it but it does support standard and also export UDFs. So it is an easier way to make the documentation.
