Planned Delivery time is not considered while creating Purchase Requisition
For materials to be procured from outside ( another plant in our case) , we have defined Planned Delivery time in Product Master .
Situation is: If demand is on 01/05/2009, system is generating a Purchase req on 01/05/2009( start and end date is same), when we have maintained 3 days of Planned Delivery time while running SNP Heuristic. In our case we dont have any procurement relationship( where we can also maintain planned delivery time) and TLane duration is Zero.
If we maintain Duration is TLane , system is calculating it correctly, in that case start date is 3 days back ie on 29/04/2009 and end date is on 01/05/2009, which is what we want.
So, why the system is not considering planned delivery time while running SNP Heuristic???
Please help with your suggestations,
