Rule reference

BR-44 The invoice line charge at lines[0].charges[0], on line 1 (id "1"), states neither a reason (BT-144) nor a reason code (BT-145)

The invoice line charge at lines[0].charges[0], on line 1 (id "1"), states neither a reason (BT-144) nor a reason code (BT-145). Every BG-28 group must carry at least one. A line level adjustment is harder to query than a document level one, because it disappears into the line net amount: the buyer sees a line total that does not equal quantity x price and has no way to find out why unless you say.

This rule is implemented and its error payload below is real, but the long-form write-up — normative text, worked example, divergence note — is not written yet. Everything the library knows about this rule is on this page. Ask and we will prioritise it.

The fix

Set lines[0].charges[0].reason to a short description, or lines[0].charges[0].reasonCode to a UNCL 7161 code, or both. Under XRechnung, prefer the free text: the mandated visualisation renders the code verbatim, so a buyer looking at the rendered invoice sees the bare code and not what it means.
