Using the CBM (cubic meters) field in Inventory Planner, you can add information about the volume of your product. This can be used to calculate volume of an order to fill a container for shipment.
In Replenishment, click the gear icon at the top of the page.
Then search columns for CBM column and click the column name to add it to your report.
Then you'll have a field in that column where you can enter information.
Finally, save your changes.
