As of version 24.... Commerce 365 for Magento has the ability to work with a different Sales Unit of Measure then the Unit of Measure on the Business Central item card. The example provided below has a base unit of measure "STUKS" which represents 1 unit and the sales unit of measure "SET" which represents 6 units.
When working with a different sales unit of measure the inventory level for the webshop will be different to the quantity displayed in the inventory field on the item card. The formula for the inventory calculation is:
(Inventory - Qty. on Sales Order) / Qty. per Unit of Measure = Inventory webshop
To make this a little more practical the calculation below will provide you with the inventory for both unit of measures.
STUKS = (32 - 5) / 1 = 27
SET - (32 - 5) / 6 = 4,5 so this will result in an inventory of 4 since only 4 complete sets can be sold.
The available inventory for the webshop will be shown on the Magento Item card in the inventory field.
