FX-SCH-A-001085: Quantity per package on a line needs a unit code

In short

Error: fails the selected checks.

FX-SCH-A-001085 means ram:PerPackageUnitQuantity on an invoice line is missing its unitCode attribute. Add the code for the unit of the contents, such as C62 for a count, then export and recheck your file.

What it means

For each ram:PerPackageUnitQuantity inside ram:SpecifiedLineTradeDelivery in the Extended profile, this rule checks that the unitCode attribute exists. It does not check the attribute's value.

Why it matters

The quantity per package can describe a count, weight or volume. The unit explains what your number measures.

How to fix it

Check the quantity per package and its unit in your invoice data. In XML, add unitCode to ram:PerPackageUnitQuantity inside the line's ram:SpecifiedLineTradeDelivery, using the unit of the contents rather than the packaging. If you have no quantity per package to report, remove that element. Export and recheck your file.
