What it means
In UBL, the check compares the schemeID count with the distinct scheme-value count on cbc:ID elements within each cac:DeliveryLocation. Repeating a scheme within that location fails, even if the identifier values differ. Identifiers without schemeID are not counted by this test.
Why it matters
Keeping one identifier per scheme gives each delivery location a single identifier value for that scheme.
How to fix it
Compare the BT-71 identifiers and BT-71-1 scheme codes within the affected delivery location. Remove duplicate entries. If different identifiers genuinely share a scheme, keep the one that should identify that location on this invoice. Correct a scheme only when it is wrong for the identifier. Check the corrected file again.
