To create a top level BOM you need to have a (manufactured) part already created via Parts. Sub-level parts can be created on the fly as you build up the BOM. Once you create a BOM at the top level you can add parts and sub-level BOMs. The operations are added along with run and set up times, workcenters and even your employees if specific work is performed by certain members of staff. A BOM can also include a drawing, which is used in the workcenter to provide a link to access drawings during production. The costing section of a BOM shows the total direct cost of the BOM for 1 unit of the BOM. By applying the gross margin the BOM record suggests a price which you can override and then use to update the part record for this item with the new price. Note that this value of price is not defined as a particular currency. If you are selling in multiple currencies you will have to adjust the contract pricing to suit.
The notes section of the BOM is intended to provide feedback and revisions to BOMs that are require.,They can be added from the BOM page, but also collected from production staff who can add notes via the works order screen.
When you create any BOM, it can be used as the basis for a template. Saving a template allows the operations and parts structure to be copied into new BOMs to save time.
Each bom record can be saved as a costing, which is a snapshot of the BOM to show the current cost breakdown. As the BOM may change over time you can revert to view the history of each BOM costing.
