How to fix UAD1421
UAD1421 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.
- 01Open the Sales Comparison Approach › Dwelling(s) › Heating area of the URAR and find Heating.
- 02Check the condition that triggers UAD1421: @ValuationUseType = "SalesComparable" AND ImprovementType = "Dwelling" and (at least one instance of HEATING_SYSTEM is not provided or HeatingSystemType is not provided in a given instance of HEATING_SYSTEM).
- 03Correct the missing, invalid, duplicate, or inconsistent value before submitting to UCDP.
- 04Use the official Single-family (SF1) sample value on this page as a reference pattern, then re-run validation.
This fix guidance is derived from the published rule message, trigger logic, report location, field definition, and official sample data available for this rule.
