UAD1678
FATALOfficial message text · Appendix H-1: UAD Compliance Rules — URAR, v1.5
Provide a description when 'Measurement Standard' = 'Other'.
Fatal — a single unresolved Fatal makes the entire submission come back NOT SUCCESSFUL (UCDP Hard Stop 401).
What triggers UAD1678
The published rule logic, verbatim:
If MeasurementStandardPublisherType = "Other" and MeasurementStandardPublisherTypeOtherDescription is not provided
- • Bound to MISMO data point
MeasurementStandardPublisherTypeOtherDescriptionat../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.
