Simultaneous Planning wih Unconstrained Plan

 Hello,

We are 12.0.6 hybrid manufacturing (Discrete and OSFM) using Unconstrained Plan.

When scheduling planned order for Make items the system calculates the Order Date according to the following formula:

Due Date-Fixed Lead Time-(Variable Lead Time*Planned Order Qty)-PreProcessing Lead Time.

Assuming Planned Order:

- for 10 units

- lead time 30 days (5 fixed+25 variable)

- order date calculation = 5+25*10

This is under an assumption that there is one resource performing that job.

We have multiple resource!

What is the way to set the simultaneous resource working within Unconstrained Plan.

Taking into account multiple resource should shorten Order Date calculation.

I will appreciate any help.
