FX-SCH-A-000855: VAT exemption reason code is not allowed

In short

Error: fails the selected checks.

FX-SCH-A-000855 means your VAT exemption reason code (BT-121) is outside the Extended profile's allowed list. Correct ram:ExemptionReasonCode using the appropriate VATEX code, such as VATEX-EU-IC for an intra-community supply or VATEX-EU-AE for reverse charge.

What it means

Checks a non-empty ram:ExemptionReasonCode in ram:ApplicableHeaderTradeSettlement/ram:ApplicableTradeTax against reason code list 25. An absent or empty code passes this test, but this does not establish whether a reason is required by other rules.

Why it matters

A recognised reason code identifies the stated reason for not charging VAT. Free text belongs in the separate reason text field.

How to fix it

Correct ram:ExemptionReasonCode in the affected header-level ram:ApplicableTradeTax. If you supply the reason as text instead, put it in ram:ExemptionReason and check that the applicable VAT rules allow you to omit the code. Do not remove a required reason simply to clear this error. Export the corrected invoice and check it again.
