Hello at all

Maybe I'm overlooking a the solution to this specific use case but somebody might be able to help me.

I have a sheet metal which in my workplan should be lasered or cut into 20 pieces. How would one define the workplan? I already got an area, machine cell and industrial machine as ressource and I have the physical product and provided part for the sheet metal and one piece. I seem to lack the possibility to define the quantity of output on the operation. Can you help me with that?
