Scheduled Changes in Material master (MM12) are not reflecting in after MRP
We have scheduled a change in Material Master using MM12. The change should become effective from 01.03.2009. (Procurement type should change from F to X from 01.03.2009). For this material we have put demand for 12 months in MD61). I am doing MRP run as on today. The requirement is that till 02.2009 (Feb'2009) I should get Purchase requisitions after MRP run and from 03.2008 (March'2008) I should get Planned Orders as procurement type has been changed from F to X fro this material.
But these scheduled changes are not reflecting after MRP run as I am getting purchase requisitions for all 12 months.
