Sorry if this has an obvious answer somewhere but so far I haven't found it. This document: Pick and Place Data Format shows the default which assumes a part number in the comment field (which IMHO is kind of a bad default as the comment field seems to be the only way to get a text field between schematic and layout for labeling things like connectors, etc. so can't be used for part info).
However my part numbers are in a custom "Part ID" field this is used to map between schematic components and the real world. I can't find a template file or dialog to set this.
How do you set the configuration of the generator to use the correct data field?
Altium Designer help shows a dialog to select the fields, I can't find that in CS.
