Why PIR is reduced after stock delivered to the customer against a sales Order in Strategy 10?

Dear Bosses,

I am new to SAP and trying to get into the real things in Production Planning module.

Now I faced a very basic challenge while doing so. I am not undersatnding in demand planning strategy 10 if a customer request is not consumed (Which I can see in MD04, that cust req is not calculated) but when goods is issued against that cust request the PIRE is also reduced from the latest PIR. What is the logic behind PIR reduction because I have already created pland order/pur req against it.

Thank you all in advance. 🙂 🙂

Hi Aritra, in planning we have so called requirement types. I assuming that LSF is the requirement type that you are seeing in your test since you've mentioned strategy 10. We have different requirement types depending on the strategy that we will be using and also we have different ways to consume these requirements. In strategy 10, delivery consumes/reduce the requirement (LFS). You can explore more about Planning requirement types and requirement consumption/reduction in in internet. But the high level logic is the same for all strategy, you create requirements and you consume/reduce these requirements.
