In the Shopify Stores(BC201010) and BigCommerce Stores(BC201000) form, the user can choose the option to show the discounts in Acumatica Sales Order as a Line Discount or Document Discount when orders are imported from External System. It cannot be both.
When Show Discount In: Document Discount
The order Level and item level discount from external system will be shown in the Discount Details tab in the document level in Acumatica Sales Order.
This is the order created in BigCommerce.
This is the Sales Order in Acumatica
Also, When the Document Discount is selected the Discount Amount revenue will be recorded against the Discount Accounts as shown below.
When Show Discount In: Line Discount
The order Level and item level discount from external system will be shown in the line item in Acumatica Sales Order.
When Line Discount is selected, by default, the discount amounts are not recorded against the discount amount
But if Post Line Discount Separately is selected in the Order Type then the discounts would be as shown below.
