Purchase orders

This table contains the purchase orders of your supply chain (replenishment you are purchasing from your suppliers), either proposed by frePPLe or confirmed.

This table is populated with new proposed purchase orders when frePPLe generates a plan. It is also possible to load purchase orders that are already approved or confirmed in your ERP system.

Field Type Description
reference string
Unique identifier for the purchase order.
For approved or confirmed purchase orders that are imported from your ERP system this field should be populated with the identifier the ERP generated.
For purchase orders newly proposed by frePPLe, a unique numeric identifier will automatically be generated.
item item The item being purchased.
location location The location receiving the purchase order.
supplier supplier The supplier shipping the purchase order.
quantity number The quantity delivered.

  • proposed:
    The purchase order is proposed by frePPLe to meet the plan (optimization output).
  • approved:
    The purchase order is present in the ERP system but can still be rescheduled by frePPLe (optimization input).
  • confirmed:
    The purchase order is confirmed, it has been populated in your ERP system (optimization input).
  • completed:
    The purchase order has been executed, but the stock hasn’t been increased yet (optimization input).
  • closed : The purchase order has been delivered and the stock quantity increased.
demands demand The demand(s) (and quantity) pegged to the purchase order. This is a generated field.
inventory status number
The Inventory Status is a calculated field that highlights the urgency of the purchase order with a red/yellow/green visual indicator.
Sorting the purchase orders using the Inventory Status column (red ones first) allows the planner to immediately focus on the purchase orders that should be treated first.
More details can be found on Inventory status
feasible boolean
Read-only boolean flag indicating whether the purchase order is violating any material, lead time or capacity constraints.
This is very handy in interpreting unconstrained plans.
criticality number
The criticality is a read-only field, calculated by the planning engine.
It represents an indication of the slack time in the usage of the purchase order.
A criticality of 0 indicates that the purchase order is on the critical path of one or more demands.
Higher criticality values indicate a delay of the purchase order will not immediately impact the shipment of any demand.
A criticality of 999 indicates a purchase order that isn’t used at all to meet any demand.
Note that the criticality is independent of whether the customer demand will be shipped on time or not.
delay duration
The delay is a read-only field, calculated by the planning engine.
It compares the end data of the purchase order with the latest possible end date to ship all demands it feeds on time.
