In Routing position > Extended you can define the Scrap of Material related to a routing position.
Example:
You must produce and fill 6 kg of paste
15% is lost during filling
Now it must be calculated how many liters of paste are needed.
Calculation
Correct formula is: Quantity: (100 – scrap% ) * 100
If you need 6 kg of finish product, then you need
6 kg : (100 - (0.15) * 100 = 7.059 kg paste
If you see the opposite:
I fill 7.059 kg paste and lose 15% =
7.059 - (7.059 / 100 * 15) = 6 kg
In the Configuration wizard > "Behavior for Routing Scrap of Material % affect to" you can define how the program should work.
The following settings are available:
Result see this example:

This is the Standard setting
Example: When a bar is sawn, a scrap rate of 10% may be incurred. If the material is ground, the bar becomes even shorter, that is a longer length must be cut beforehand,
Example: We need a finished product with a length of 250 mm.
We start with 308.65 mm - sawn : scrap 10% = 277.78. Continue with 277.78 mm - ground : scrap 10% = 250 mm.
Calculation
Correct formula is: Quantity : (100 – scrap% ) * 100
Position 20 we need 250 : (100 – 10) * 100 = 277.78 The value is entered into the production BOM item, column "calculated scrap" as fix value.

Notes:
•This field is only visible, if in Configuration wizard > Master data > routing > operation related material scrap" is enabled.
•The Item Report – Item Structure report does not support the Material Scrap factor on Routing Level.
•Enable this option only if absolutely necessary; the computation will take considerably longer.
•In work order this field is blocked, because scrap of material is determined only at the moment of creating the work order
•When checking which routing positions are considered, the following criteria apply:
- Validity date
- Active (no formula, no quantity check)
- Variants (A–Z)
Not checked:
- Variants formulas, Product configurations
