1 Open the aPriori client and select Tools > VPE Toolset.

2 Click the BOM Loader icon. The BOM Loader opens and prompts you to select the file to import.

3 Select a wire harness or PCBA .csv data import file (NOT the component library file). For a new installation, this might be a demo file created for you by aPriori Professional Services with a name like “WIRE-HARNESS-001 - formatted.csv”, delivered in a folder with a name like “Wire Harness Demo Data”.

4 Assuming that this is the first import done on your installation, the aPriori BOM Loader prompts you to enter a mapping name. Provide a descriptive name such as "Wire_Harness" (or “PCBA”).

5 Ensure that this checkbox is checked in the upper-right corner.

6 One by one, click the aPriori Field cell for each Input File Column header and select the appropriate plain-English display name as shown in the screenshots below. (Different BOM versions may use different naming conventions, such as underscores vs spaces and initial caps.)

7 Click the Save Changes icon in the upper-left corner when done.
