PIR consumption for MTO scenario

Hi All,

I know that using strategy 50 we can consume the sales order with planned independent requirements using the requirement type VSE. Is there a way that stock transport order can also be consumed with PIR's if the requirement type is VSE? My requirement is that material should be a make to order (customer stock assignment) but sales orders and STO's should consume PIR's. If it is not possible through standard process, can the following BADI MD_PIR_FLEX_CONS be used to get the desired output?

Thanks
