How to fix UAD1658
UAD1658 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.
- 01Open the Does Not Display › Does Not Display › Does Not Display area of the URAR and find Does Not Display.
- 02Check the condition that triggers UAD1658: there is no instance of RELATIONSHIP with @xlink:arcrole = "urn:fdc:mismo.org:2009:residential/DATA_SOURCE_IsDataSourceFor_MARKET_TREND" linking DATA_SOURCE to MARKET_TREND where @ValuationUseType = "SubjectProperty".
- 03Correct the missing, invalid, duplicate, or inconsistent value before submitting to UCDP.
- 04Re-run validation after the change so conditional downstream edits are checked again.
This fix guidance is derived from the published rule message, trigger logic, report location, field definition, and official sample data available for this rule.
