How to fix UAD1320
UAD1320 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.
- 01Open the Site › Site Features and Impact to Value / Marketability › Detail area of the URAR and find Detail.
- 02Check the condition that triggers UAD1320: SiteFeatureType = "Drainage" and (at least one instance of DRAINAGE_IMPACT_REASON is not provided or SiteDrainageReasonType is not provided in a given instance of DRAINAGE_IMPACT_REASON).
- 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.
