Narrower sense on dragging table maps into a datasource node of a query

Hi,

I noticed that a map from the AOT can be easily used in a query, view, report or form by dragging it to its datasource node.

The only way i found to retrieve data via table maps is to use them as a temporary table. This is quite OK, if you only want to read records via a map. For writting data to a table it is necessary to tell the map which table is the the “real” datasource. I’ve got no idea how to do that? (AX 2009)

Got any ideas?
