Rootstock Replenishment Planning (RP) is the softwareengine that will use the sales order and forecast demands in conjunction and by reviewing item inventory balances will generate planned supplies in a time phase manner to offset the outstanding demands for Products being sold (or forecasted sales).
Specifically, RP generates what are termed planned purchase requisitions for purchase or subcontract items. For firmed (or greater supplies) it generates reschedule or excess messages when, and if, appropriate.
Rootstock Replenishment Planning (RP) uses information from Sales Order Management to drive the Product level demands. Forecast demands, for not only these end items can be entered as well. A forecast demand for an item denotes the start period date and the end period date and the quantity forecasted for that period. RP will perform the traditional ‘netting’ and plan to the greater of the Sales Order Demand and Forecast demand (by period).
The RP Engine uses the typical algorithms in the industry and review the demands and safety stock requirements netting out the inventory and firmed (or greater) supplies and first suggest reschedules for firmed (or greater) supplies and then create planned supplies as appropriate.
RP can be planned by division (P&L entity) and by site (DC) as well as by project (in those divisions where project control is applicable). It uses planning policies such as ‘lot for lot’ or days cover. For a requisition it will determine the scheduled firm date, purchase order place date, date it is due on the receiving dock as well as the due date it is to be stocked. For those parts identified as items to be planned using “re-order” point logic, the RP engine can also perform re-order point computations rather the balancing of demands and supplies.
