How to fix UAD1172

UAD1172 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.

02Check the condition that triggers UAD1172: @ValuationUseType = "SalesComparable" and UnitIdentifier is not unique across all instances of PROPERTY_UNIT_DETAIL.
03Correct the missing, invalid, duplicate, or inconsistent value before submitting to UCDP.
04Use the official Single-family + ADU (SF3) sample value on this page as a reference pattern, then re-run validation.
