Hello
You can create a different production version for each routing.
In order to split the planned orders for different production versions, you can use a quota arrangement, however, they will be split on a fixed quantity.
If you are using PIRs, an option is to define the production directly on transaction MD62. You can do that on tab 'schedule lines', where there is a menu option to open the field production version for input.
