Hi all,
I've some trouble configuring a product forecast and using different data types as product sold.
I'm trying to follow the 1st example in this link: docs.microsoft.com/.../forecast-different-data-types
but I'm not able to get number of product sold becouse I think I should select "quantity" but the only values are "Import Sequence Nr", "Line Item Nr" and "Sequence Nr".
Please see the screenshots attached:

.
When am I wrong? Can Anyone help me please?
Thank you in advance.
