Re: Reduction of PIRs by sales orders

Hello Nikos,

Please check your Sales order requirement type, It should be KSV for planning strategy 40. 

Also check the Consumption mode and Consumption Period, base on this data PIR is reduce when sales order comes.

Please check SAP note 1715491 for same issue..

Please check and revert

I hope this information helpful to you
