I have added a standard field to an extractor. There was no need to put any fancy code. I placed this new filed in the append structure. When I run RSA3, I can see the new field populated with values. So I assume r/3 side is good.
Issue: I replicated the data source in BW. But the field is not showing up in Transfer structure/Transfer rules list to assign it to a BW info object.
Other things I have noticed in BW: Source systems
>Find data source
> right click on Data source and hit Object overview --->>This newly added field is in other fields section not in charactersticis list.
