The BOM Checks dialogThe BOM Checks dialog


The BOM Checks dialog is used to define the error reporting levels for each of the possible violations associated with Design Items or Part Choices. The BOM Check process runs automatically in the background whenever an ActiveBOM edit action is performed, or whenever the BOM Items are refreshed, such as after a project compile or after the  button is clicked.

Detected BOM violations that have a report level of Warning, Error or Fatal Error are flagged in the BOM Status column of the ActiveBOM grid. Note that multiple violations can be detected; hover over the icon in the BOM Status column for details. Alternatively, enable the BOM Status column in the Columns list in the ActiveBOM Properties panel (on the Columns tab) to display a text description in the BOM Items grid.

The BOM Checks section of the ActiveBOM Properties panel lists all detected violation types in the current ActiveBOM. Click the filter icon next to a type to filter out all violations except that type.

To access the BOM Checks dialog, click the  button in the BOM Checks section of the ActiveBOM Properties panel.
