The Customer card has fields for Country and Tax/VAT Registration No. We're writing an integration between Dynamics GP and Business Central and want to push these fields from GP to BC, with the Country field coming from the GP customer's primary address. In GP, you can have a Country and Tax/VAT Registration No. which don't match, but in Business Central the Tax/VAT Registration No. must match one of the Tax/VAT Registration No. Formats for the customer's country. Is there anyway to make this check less strict?
