Strategy production no greater than PIR

[alex_alex85]

Hi

We have production with PIR and Sales orders. Our Strategy is 40. In certain way it works ok.

Scenario 1: PIR = 1000, Sales order = 700. After MRP run Planned order = 1000. - it's ok for us.

Scenario 2: PIR = 1000, Sales order = 1200. After MRP run Planned order = 1200. it's not ok because Planned order was created greater than PIR.

Requirement is - Planned order should behave like in strategy 40 but created no greater than PIR. So expected result for Scenario 2 is Planned order = 1000.

Which strategy should we use?

Thanks.

Hello alex_alex85

I think you should use either Net Requirements Planning (10) or Gross Requirements Planning (11) depending whether you want to consider existing stock or not.

It does not suit. In this case, if we have only Sales order but no PIR - then Planned order will not be created at all.

Moreover, strategy 10 ignores Sales order. But we need that Sales orders considered but consuming by PIR as it works in strategy 40. Because for each Sales order we receive Planned order considered Sales order dates.

alex_alex85 Strategies 10 and 11 are based on demand plan only. They don't consider sales orders. Strategy 40 considers sales order, but it considers them always. You need to decide whether you want to consider sales orders during planning or not. z

Currently you want to consider sales orders only if they don't exceed the demand plan. I don't think there is such a planning strategy in standard. It would be pretty hard to implement it. The strategy looks simple in your question, but consider multiple PIRs and multiple sales orders. Sales orders are assigned to PIRs only dynamically, there can be N:M relationship between PIRs and SOs. Imagine that you create a sales order (A), limit its impact on MRP planning according to not consumed PIRs. The another sales order (B) that was created earlier gets deleted. Now you have more unconsumed PIRs so you could consider the sales order (A) in greater extend in the MRP planning.
