What it means
The rule checks unitCode on ram:UnitQuantity within ram:IncludedReferencedProduct under the line's ram:SpecifiedTradeProduct. A non-empty value must appear in the profile's unit code list. An empty or missing value does not fail this test; FX-SCH-A-001152 separately checks that the attribute exists.
Why it matters
A shared unit code lets software interpret what the included product's quantity measures.
How to fix it
Correct unitCode on the affected ram:UnitQuantity. Use the code for the actual unit, such as C62 for individual units, KGM for kilograms or HUR for hours. Do not use informal labels such as pcs or kg in place of those codes. Save or export the corrected file and check it again.
