UAD1639
FATALOfficial message text · Appendix H-1: UAD Compliance Rules — URAR, v1.5
Provide the number of pending sales, even if the value is 0.
Fatal — a single unresolved Fatal makes the entire submission come back NOT SUCCESSFUL (UCDP Hard Stop 401).
What triggers UAD1639
The published rule logic, verbatim:
If MarketInventoryCount is not provided for the instance of MARKET_INVENTORY with MarketInventoryType = "PendingSales"
- • Checked for the Subject property.
- • Bound to MISMO data point
MarketInventoryCountat../VALUATION_ANALYSIS/PROPERTIES/PROPERTY/MARKET/MARKET_INVENTORIES/MARKET_INVENTORY/
How to fix it
On the URAR, this lives at: Market → Search Result Metrics → Pending Sales. 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.
