Co/By-Products Table

In Business Central, Co/By-Products are treated as similar types of items but are added at different stages of the production process.

Co/By-Products are often manufactured alongside the main item during production. While Co-products are typically expected outputs, By-products are produced incidentally. The system handles both types of products within the same framework but with specific functionalities based on their timing in the production process.

Key Features

  • Co/By-Product Assignment: You can assign Co/By-Products either directly to the Production Order Lines or to the finished product.
  • Routing Consistency: Co/By-Products will use the same routing as the main item. If a Co/By-Product has a different routing in its item card, the system will disregard it.

    If a different routing is required for a Co/By-Product, the user can add it as a new item on a new Production Order Line and refresh the Production Order with “Lines” set to No. This enables the Co/By-Product to use its own routing, and the cost will be calculated as it would be for any finished item.

  • Capacity Cots Allocation: The system posts capacity costs (such as run and setup time) only when the Main Item Production Order Line is posted. You can choose the method for allocating these costs:
    • Quantity Proportional: Allocates total capacity costs proportionally across all output postings.
    • None: Allocates all capacity costs to the main item output.

    Cost allocation doesn’t apply to items with Standard costing method. When this costing method is set on item the standard cost applies.

  • The capacity cost allocation method is a company setup that can be changed via the Manufacturing Essentials Setup page. Check Capacity Cost Allocation for further information.
  • Material Cost Allocation: Co/By-Product will each have their own Bill of Materials (BOM) to support material cost allocation.
  • Rounding Precision: The calculated cost amount will be rounded to a maximum of two decimal places.

Co/By Products Table

You can define Co/By-Products from the Item card. This enables you to associate secondary products to main production items.

You can access the Co/By Products Page via:

  • Item Card: Go to Related > Bill of Materials > Production > Co/By-Products.
  • Item List: Go to Related > Assembly/Production > Production > Co/By-Products.

This would open the list of the related Co/By-Products for the selected Item.

Fields

Field Description Mandatory/Optional
Item No. Specifies the main item number. Mandatory
Variant Code Specifies the main item variant code.
If the Variant Code field is left empty, the Co/By-Product line will apply to all variants. This validation bypasses the “Variant Mandatory if Exists” setting in the Inventory Setup.
Optional
Unit of Measure Code Specifies the main item unit of measure code.Is defaulted with items’ base unit of mesasure code. Can’t be changed. Mandatory
Co/By-Product No. Specifies the Co/By-Product item number. The Co/By-Product No. cannot be the same as the Item No. An error message will appear if the user attempts to insert the same value. Duplicate Co/By-Product lines for the same Item No. are not allowed. Mandatory
Co/By-Product Variant Code Specifies the Co/By-Product variant code. Optional
Co/By-Product Unit of Measure Code Specifies the Co/By-Product Unit of Measure code. Mandatory
Quantity Per Defines the quantity of the Co/By-Product per unit of the main product. Mandatory

Main Item Where Used

The Main Item Where Used page shows where an item is used as a Co/By-Product.

Access this page from the Item Card page to view linked items and quantities.
