We have some long delivery items in BOM for which we are trying advance procurement. We have maintained strategy 70, item category'L' in material master and attached the material to an activity which is 2 months prior to the scheduled production. We generated PR for this item and created PO however during the Project MRP run, system is generating PR again for this item. Please inform which are all the settings required to prevent the PR getting generated again during project MRP.
Any help on this issue is highly appreciated.
