You can define a subsidy individually for each means of production: In the admin area under Means of production/capabilities & formulas.
You can specify this as a percentage and as a fixed value in the number of sheets.
It is also important that you can calculate an additional subsidy for each operation. To do this, go to the corresponding work process under Admin Area/Templates/Tasks processes and enter the subsidy as a formula at the very bottom of General, e.g.
(Total processed goods*Waste rate)+Absolute waste
But you can also use variables like:
Number of sheets
circulation
Incoming processed goods
Number of folded sheets
For this you always look at what exactly my task is based on and which variable is responsible for my board.
Only then can Keyline correctly calculate the subsidy over the entire production process.
