Hi All,
Please help.
The sales order creation date for FERT is 30.09.2008, delivery date is 15.11.2008. The planned order starting date for FERT(in house time 3 days & GR processing is 7) is on 05.11.2008 & finish on 08.11.2008.
The PR date for VERP(planned del days 25 & GR process time 5 days) is suggested by system is 26.11.2008. This date is exceeding the delivery date of sales order i.e. 15.11.2008.
MRP run as per MD05 is taken place on 17.10.2008. As MRP calculates the backward then for PR of VERP it should calculated back from 15.11.2008 & should suggest the 05.10.2008. but as MRP date is on 17.10.2008 system would recalculate it forward from 17.10.2008 & would have suggested the 26.11.2008. Could you please suggest why this has happened? If sales order has been created on 30.09.2008 then why MRP run has taken place late on 17.11.2008?
IMP: The lot size MB is given in MRP 1 of VERP i.e. priod start = delivery date (transaction OMI4). Means system should consider dekivery date for verp calculating from period start i.e. month start then should recalculate.
