Why This Error Matters

How to Fix It

1

Locate the line charge

Find the InvoiceLine/AllowanceCharge element with ChargeIndicator=true that is missing a reason

2

Add reason code

Add AllowanceChargeReasonCode with a valid UNTDID 7161 code (e.g., ABK=Miscellaneous, FC=Freight, AAA=Advertising)

3

Optionally add reason text

Add AllowanceChargeReason with a description like 'Miscellaneous charge' or 'Handling fee'

Common Causes
