In the old Excel BOM, if you had a part with multiple configs, and all the properties referenced in the BOM were identical, then the BOM considered them to be the same item and summed them together. With the new one, you have grouping choices, but it appears that you can't get to that same functionality.
If you select "Display configurations of the same part as separate items", it does just that - all configs of a part are separate items in the BOM - usually the desired option.
If you select "Display all configurations of the same part as one item", it does just that - all configs of a part are lumped together in the BOM, and this is for all parts. So, it takes all the Gr5 capscrews that are all configs of the one part file, and calls them one item. Hardly desirable.
If you select "Display configurations with the same name as one item", it finds everything with the same User-defined name and lumps them. This doesn't work in this instance, because there may be several items that have the name of "BY ELEC" to indicate that the electrical controls group is buying those items, rather than the mechanical group buying them. One option would be to check this grouping, but then all of the "BY ELEC" items would have to be uniquely named except for the desired two, so they wouldn't all get lumped together.
So, it looks like another option would be desirable. This one would be "Display all configurations of the same part that have identical BOM referenced properties as one item." This would optionally provide the same functionality as the Excel BOM. Am I missing anything here, or is it time for an ER?
