how does a work order know what BOM to print when you click "Print BOM" button on a work order?

AI generated answer (using internal Slack threads):

When you click the "Print BOM" button on a work order, the system knows which Bill of Materials (BOM) to print based on the BOM that is associated with the item being manufactured in the work order. The BOM is set up in the item record and is linked to the work order when the work order is created. If you have multiple BOMs for an item, you can set one as the preferred BOM, and that is the one that will be used by default when creating a work order for that item. If you want to use a custom BOM layout, you need to set it as the preferred layout in the BOM Transaction form. Even if you have a custom BOM layout set as preferred, the "Print BOM" button on the Work Order screen will still print the standard BOM layout unless you change the button behavior to target the custom layout. To do this, you need to edit the Transaction Form > Bill of Materials and set your Print Template there. Then on the Work Order customization, your linked form is the above "Bill of Materials" transaction form. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
