ReportWe will begin utilizing MRP to handle forecasted finished good demand for which we will create a combination of MPS Mfg. Orders for forecasting component demand, as well as Mfg. Orders linked to Sales orders for firm, configured finished goods. Such is our business model.
However, we are also a Service organization, supporting tens of thousands of core units in the field. As such, our Field Service department also creates inventory demand for components and that demand is not driven by transactions that support traditional forecasting.
Everything I have read online suggests that using PO Generator and MRP together can be problematic. However, I have not found good information why that is.
I had planned on using MRP for Sales to Manufacturing demand in combination with the PO generator functionality for the demand coming from Field Services. We have hundreds of sites, one for each technician. We simply have too many sites to run MRP for all of them. I suppose we could emulate the PO Gen functionality for Subordinate..Mater inventory sites for 1 Inventory site that would reflect the demand based on the Order Point or Order up to level replenishment level policy for all "children' item site combinations. Then input that forecasted demand into the MPS. We could create a fake item to represent a "build", and use the component demand as the picklist for this planning MO....
Any thoughts on this approach or information pertaining to why PO Generator and MRP should not be used together?
