Bank/Cash Receipt in VAT Instead of Invoice

You most likely have a VAT line filled in on the bank or cash document. In that case, the paying document is included in the VAT return basis instead of the invoice. When matching a document, the paying document must correctly use line 0 - No VAT impact,
and the relevant lines should be filled in on the invoice. Since VAT is not itemized on the paying document, a zero value would incorrectly appear in the VAT return.
