FX-SCH-A-001084: Package quantity unit code must be an allowed code

In short

Error: fails the selected checks.

FX-SCH-A-001084 means the unitCode value on an invoice line's ram:PackageQuantity is not in the Extended profile's unit code list. Replace it with a listed code that matches your package quantity, then export and recheck your file.

What it means

This rule compares a non-empty unitCode value on ram:PackageQuantity inside ram:SpecifiedLineTradeDelivery with the Extended profile's unit code list. An absent or empty value does not fail this test. FX-SCH-A-001083 separately checks that the attribute exists.

Why it matters

Using the profile's unit codes gives the quantity a consistent meaning across software.

How to fix it

Correct the package quantity's unit in your invoice data. In XML, replace unitCode on ram:PackageQuantity inside the line's ram:SpecifiedLineTradeDelivery with a code from the profile's list. For a plain count, C62 identifies the unit one. Do not substitute free text such as pcs. Export and recheck your file.
