UAD1246

FATAL

Official message text · Appendix H-1: UAD Compliance Rules — URAR, v1.5

A numeric identifier ('Comparable #') must be assigned for each GRM comparable. For assistance with this message, contact the appraisal software vendor.

Fatal — a single unresolved Fatal makes the entire submission come back NOT SUCCESSFUL (UCDP Hard Stop 401).

What triggers UAD1246

The published rule logic, verbatim:

If @ValuationUseType = "GrossRentMultiplierComparable" and PropertyOrdinalNumber is not provided

• Checked for: Gross Rent Multiplier Comparable.
• Bound to MISMO data point PropertyOrdinalNumber at ../VALUATION_ANALYSIS/PROPERTIES/PROPERTY/COMPARABLE/COMPARABLE_DETAIL/

How to fix it

On the URAR, this lives at: Income Approach → Gross Rent Multiplier Comparables → Comparable #. Complete or correct that field in your form software, regenerate the package, and re-check before submission.

Because this is a Fatal edit, do not submit until it is resolved — one Fatal bounces the whole package.
