What it means

For a whole-invoice charge (BG-21), this rule checks the non-empty unitCode value on ram:BasisQuantity against the profile's unit code list. It applies where ram:ChargeIndicator/udt:Indicator is true. This test allows an empty code.

Why it matters

The unit code identifies what the quantity used as the charge's basis measures.

How to fix it

Correct the basis quantity's unit on the affected charge. Examples include C62 for individual units, HUR for hours, KGM for kilograms and MTR for metres. In XML, correct ram:BasisQuantity/@unitCode inside the header-level ram:SpecifiedTradeAllowanceCharge whose ram:ChargeIndicator/udt:Indicator is true. Export and recheck your file.
