Inventory Commodity Code > MRP TabFields
Planning Policy: Planning methodology used by MRP. Values = ‘Lot for Lot’ (Planned Supply Qty = Demand Qty), ‘Days Cover’ (combines Demands for the number of work days defined in ‘Policy Qty’), ‘Reorder Point’ (plans ‘Policy Qty’ when on-hand inventory + open orders drops below Safety Stock Qty) and ‘No MRP Planning'.
Policy Qty: Works with MRP Policy in the calculating of supplies, driving the method of MRP supply calculation for this Commodity Code. If ‘Lot for Lot’, Policy Qty will be set to 1, ‘Days Cover = number of work days to combine, and ‘Reorder Point’ = Qty to order.
Minimum Qty: The minimum quantity that MRP will plan a supply order to. If set to 8 and the demand is 4, the supply order will = 8. When the demand is greater than the Minimum Qty set, the supply order will match the actual demand quantity up to the Maximum Qty.
Maximum Qty: Represents the maximum supply quantity planned by MRP. MRP will not plan an individual supply order in excess of this quantity.
Supply Multiplier: This field carries a Supply Multiplier used on supplies (Work Orders and Reqs) created by MRP (only). Just prior to creation, supplies are adjusted up as necessary to be a multiple of this value. This adjustment does not affect MRP calculations.
NOTE In effect, this field does NOT affect the number of planned Work Orders or Inventory Requisitions that are created after running MRP. The rounding logic within this field DOES NOT apply to supplies created from any other place outside of MRP (i.e. UI, csv imports, etc)
Safety Stock Qty: Denotes the Safety Stock quantity which MRP planning will ensure that inventory does not drop below. When using ‘Reorder Point’, when on-hand inventory drops below this quantity, a Reorder Point order will be planned (using the Policy Qty).
Home Project Indicator: The value in this field denotes whether the items associated with the given Commodity Code are to be purchased and inventoried in the ‘Home Project’ (common material) or ‘Not Home’ (Project-specific).
Planning Policy Days Cover – ExampleDays Cover is a look-ahead approach to planning which ensures that when a supply order is needed and created, its quantity will be for a certain number of days’ supply. That number of days is the sum of the current day’s demands plus demands over the span of the Policy Quantity days.When processing an item with an MRP Policy of “Days Cover”, MRP will calculate the projected on-hand balance day by day, and create a planned supply on the first date that the projected balance goes negative. The quantity of that order will be the sum of the demand for that date through a certain number of work days into the future, the number being the number of days specified in the Policy Quantity field. Work days are determined from the work days on the Division Shop Calendar.If a purchased item has an MRP Policy of Days Cover, and the Policy Quantity is five.Suppose the start date is 04/23 and there are two non-working daysMRP is looking from 4/23, plus five work days forward from the planning date to 4/30, to make sure that there is enough supply to cover demand through the next five work days. If not, it plans a supply order. That supply order includes any demand from any intervening non-work days,The planned requisition created for 4/23 is for a quantity of eight, the sum of demand from 4/23 through 4/30.SEE ALSO
