The installed Excel BOM Templates (XLT) available within the Generate Outputs > Bill of Materials output from SOLIDWORKS PCB 2019, require the corresponding data to be set within the Configuration Manager for each of the templates columns.
This document shows columns used in each of the installed templates. Referencing this will ensure the correct and full data is provided for creating the desired report. If any data for a column is missing, then the resultant output, as well as not include that column data, will show the column formula at the top of that column.
The Excel Worksheet and PDF outputs use the templates provided.
