How to: Create Production BOMs

A production BOM holds master data that describes the components and subassemblies used in the production of a parent item. Once a production order is created for that parent item, its production BOM will govern the calculation of material requirements as represented in the Prod. Order Components window.


  • Item cards are created for parent items and their components. For more information, see How to: Set Up Items.

  • Gather all data about item structures: Top-level items, subassemblies, components, and their interrelation.

To fill in the production BOM header

  1. In the Search box, enter Production BOM, and then choose the related link.

  2. Create a new production BOM.

  3. In the No. field, number the production BOM, for example, the same as the parent item.

  4. In the Description field, name the production BOM, for example, the same as the parent item.

  5. In the Unit of Measure Code field, select the parent item’s unit of measure code.

  6. To edit the BOM, set the Status field to New or Under Development. To activate it, set the Status field to Certified.

To fill in the production BOM lines

  1. In the Type field, select whether the item on this BOM line is an ordinary item or a production BOM. If the item on the line is a production BOM, then it must already exist as a certified production BOM.

  2. In the No. field, look up and select the item or production BOM in question, or type it in the field.

  3. In the Quantity Per field, enter how many units of the item go into the parent item, for example, 4 wheels for 1 car.

  4. In the Scrap % field you can enter a fixed percentage of components that are scrapped during production. When the components are ready to be consumed in a released production order, this percentage will be added to the expected quantity in the Consumption Quantity field in a production journal. For more information, see How to: Register Consumption and Output.


    This scrap percentage represents components that are scrapped during production when picking from inventory, whereas the scrap percentage on routing lines represents scrapped output before putting on inventory.

  5. In the Routing Link Code field, enter a code to connect the component to a specific operation. If the column is not visible, open the shortcut menu for the column headings, and then choose Choose Columns to add it.

    Routing links between operations and components ensure that material consumption is not posted until it has actually been consumed. In addition, routing links provide a process view in the Production Journal window where components are listed under the linked operation. For more information, see How to: Create Routing Links.

  6. To copy lines from an existing production BOM, on the Actions tab, in the Functions group, choose Copy BOM to select existing lines.

  7. Certify the production BOM.

  8. You can now attach the new production BOM to the card of the parent item in question. For more information, see How to: Set Up Items.


To recalculate the item’s standard cost from the item card, on the Navigate tab, in the Bill of Material group, choose Manufacturing, and then choose Calc. Standard Cost.

Quick guides for manufacturing are available in a document that you can edit and print in Microsoft Office Word. The file, called “Quick Guides – Manufacturing Foundation.doc”, is installed in the documentation folder of your client installation.
