Batch-specific UoM Proportion/product unit of measure GON invalid for item 000010 Message No. VL382

[TheSAPJourney]

I've a scenario where I have a finished product managed by a Batch-specific UoM with type: Product Unit, and I am facing this error message when I try to make a delivery with the Alternative UoM (Product Unit) Reference to a Sales order with the Base UoM
"The sales Unit (Also the Base UoM) in the sales order is "KG" and the Alternative/required UoM in the Outbound delivery is "GON" 

"GON" UoM is a custom UoM created equivalent to the UoM: "BAG"

Note: this scenario has been tested in MM by creating a PO with UoM: "KG" and MIGO GR by UoM: "GON" and it's working properly

The error message:

Proportion/product unit of measure GON invalid for item 000010
