• Material Requirement Planning (MRP) run typically focuses on future demand. If a demand of future date (xx.mm.yyyy) is already created and also request document was created, it means system is expecting that for this product the demand will be fulfilled by this future date.
• When a backdate demand comes into the picture (dd.mm.yyyy), where already a futuristic demand is present, then system will not consider this unexpected demand as already a request of future date demand is present in system. This is an expected system behavior.

(xx.mm.yyyy and dd.mm.yyyy represent a date of the calendar whereby xx.mm.yyyy is later than dd.mm.yyyy).

Whenever there is any future date proposal created and also released and a situation happens that a demand got created with backdate of the previous future date requested document, then the request document having open quantity need to be cancelled and again MRP run to be performed.
