Is it necessary to connect an order charge to an order line, in order to get the charge included in the Intrastat report?

According to documentation on the ‘Collect Intrastat Data’ page:

Charges related to purchases and sales will be included only if the Intrastat Exempt check box has been cleared in the charge lines

Our charges are usually not connected to a specific order line. They are generic header charges summarizing how many pallets and package material that was used on the order. And these charges are not automatically included on the Intrastat report, even though they are not Intrastat Exempt on the Sales Charge Type.

It feels like it should be possible to include sales charges without connecting them to a specific order line. This was possible in a previous ERP system that I used, as long as a commodity code was connected to the sales charge type.

Can this be configured in IFS, to include header charges in Intrastat report, without connecting the charge to a specific order line?
