UAD1677
FATALOfficial message text · Appendix H-1: UAD Compliance Rules — URAR, v1.5
Provide the 'Measurement Standard' (i.e., ANSI, AMS) used for the appraisal.
Fatal — a single unresolved Fatal makes the entire submission come back NOT SUCCESSFUL (UCDP Hard Stop 401).
What triggers UAD1677
The published rule logic, verbatim:
If SketchExistsIndicator = "true" and MeasurementStandardPublisherType is not provided
- • Bound to MISMO data point
MeasurementStandardPublisherTypeat../VALUATION_ANALYSIS/VALUATION_REPORT/VALUATION_REPORT_DETAIL/
How to fix it
On the URAR, this lives at: Sketch → Measurement Standard. 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.
