If we use strategy 40 then it does create production order if we run MRP but we don't want system to create process order at the same time we put sales order in system.
MTS - Strategy 40 scenario:
Create sales order
Run MRP, if no stock to confirm sales order system create production order
Our req:
We don't maintain inventory of customer material. So moment we recieve SO, we manufacture and ship to customer, but in our business there frequent chance of selling same material to different customer. So we can't make it to MTO also.
System should create production order at the time of entering SO before running MRP.
