I am looking to integrate configuration specific part numbers and descriptions to the exported step files.

The fields are showing correctly on a test assembly and bom table I created within solidworks, but when processed through #TASK those parameter show up blank. 

I have tried 

PartNumber

PartNo

SW-BOM Part Number

and a number of other without luck

The only workaround I have so far is to reference a totally new custom property in the design table that mirrors the part number column. 

I would have to do something similar to add the description also. 

Anyone have any luck doing this?
