I am currently writing a macro to extract component information (i.e. quantity, part number, etc.) from top-level only type BOMs, and I would like to use the GetComponents2 and GetComponentsCount2 methods to get information about the BOM line items in BOMs with more than one configuration.

I was playing around with these 2 methods using the example provided on the API help website, and I ran into some strange results:

When the drawing BOM was "Top-level only" type

• GetComponents2 always returns empty array
• GetComponentsCount2 always returns 0, but sets ItemNumber and PartNumber strings correctly

When the drawing BOM was "Parts only" type

• GetComponents2 returns correct array of components
• GetComponentsCount2 return correct quantity and sets ItemNumber and PartNumber strings correctly

Strangely enough, I noticed that the deprecated GetComponents and GetComponentsCount methods work correctly for both top-level only and parts only BOMs (but they do not have the capability of differentiating between BOM configurations).

Has anyone else had issues getting these 2 methods to work? If so, is there a way to make them work correctly on "top-level only" BOMs?

***Note: This issue only seems to appear in SW2016. The example referenced above worked fine in SW2015...... ****
