RE: Business Central API adjust VAT on Sales Invoice
Hi,
You can not adjust the VAT amount when you create sales invoices via the API, You can only change the VAT posting group that is used.
If you posted your sales through a journal you have some more control over the VAT amounts because you would be able to manipulate the VAT base amounts.
You should try to figure out why the differences occur and fix the root cause. Maybe you need to round your prices before you create the sales invoice?
