I am working on an immlementation project for a F&B business and there was a requirement to genearate forecast requirements thro' MRP in one of their HQ company for which it got about 300 stores located else where. MRP is based on their stores consumption of the past and expectations for the next 3 weeks. But the demand does not come through any Sales orders. But normally they have fixed delivery days in which their stocks are replinished from HQ company. Presently we have not decided how to handle these stores either as their internal customers or seperate plants? The only information we got is the stores have some POS system where their daily sales can be captured into SAP.
Could someone please advice me how the MRP can be calculated without a sales order? Can there be some way where we can input just the forecasted values?
