Specific customer dispatches not on Intrastat

hi

we have a few customer dispatches that do not show on the Ax intrastat report, all others are working fine.

It is not item that is the issue, as the same item works fine on other customer dispatches, which leaves the customer record. What are the necessary fields in the customer record to generate intrastat records? the customer has a country code, vat group and number setup already

any ideas?
