Carrying cost period missing or unknown

Inventory policy rows have no Unit Carrying Cost Period, or one that is not day, week, month or year. The period decides what a day of inventory costs, so Create Scenario does not save the scenario, and Network Optimization and Cost to Serve stop on such a scenario.

What to do

Map a column holding the period on Map Inventory Policy, or correct the values on the rows the message lists.

Where it comes from

Shown by Center of Gravity, Consolidate Shipments, Cost to Serve, Create Scenario, Network Optimization, XYZ Segmentation. It is one of the messages about the scenario.
