I was confused btw strategy 10 and 11 and after different test cases, I understood that it is more than just consideration of avail stock.
Stratergy 11 reduces PIR as soon as GR is posted for process order.
System should consider available stock(stratergy10) and PIR should be reduced on GR of order(like 11).
Can this be achieved by making a custom stratergy?
Am i missing something here as this requirement is not provided by SAP in stnd, any reasons for this?
