Typical posting looks like this:
Dr "By-product stock" (B/S)
Cr "By-products produced" (P&L and cost element) posted to production order
In your cost component structure you have to include "By-product produced" costs element.
In transaction OBYC it is: GBB/ZOF (not GBB/AUF as suggested earlier).
In the material list or BOM for the primary product or process, you enter the by-product with a negative quantity. If the by-product is indicated as being relevant to costing, the total cost of the process is reduced by the costs of the by-products.
The cost of goods manufactured for a by-product can be calculated in two ways:
- A price from the material master is used. The costs of goods manufactured for the by-products are arrived at by multiplying the output quantity by the price, and appear in the itemization of the cost estimate as negative values.
If you don’t want to include the costs of the by-products, deselect the relevant to costing indicator in the material list item.
- The by-product can be manufactured using an alternative production structure, and a cost estimate for the by-product already exists. In this case, this cost components of the cost component split for the by-product are subtracted. The cost of goods manufactured for the by-products is arrived at by multiplying the output quantity by the costing results of the by-product from the alternative cost estimate
