I have an externally procured product which has a sales order for delivery date of 01/06/2009 created on 01/06/2009. Since there was no stock on 01/06/2009, system confirmed 0 qty on 01/6/2009 and confirmed the ordered qty on 02/17/2009( Pland Del time in material master for this material: 42 days). When MRP ran for this material Purchase requisition was created for 04/01/2009.
I need your help understanding why system is doing all forwards. We want the system to propose a purchase requisition backwards not forwards. Pl. help me how to fix this thing.
Thanks in advance,
