FORM UC-36 (REV. 09-2026)UCDP MANDATE: 2026-11-02
UADCHECKPre-submission inspection of UAD 3.6 packages

UAD1507

FATAL

Official message text · Appendix H-1: UAD Compliance Rules — URAR, v1.5

The 'Date of Signature and Report' must include year, month and day.

Fatal — a single unresolved Fatal makes the entire submission come back NOT SUCCESSFUL (UCDP Hard Stop 401).

What triggers UAD1507

The published rule logic, verbatim:

If ExecutionDate does not include year, month and day (YYYY-MM-DD format) in a given instance of SIGNATORY

  • Required format: a full date, CCYY-MM-DD (e.g., 2026-03-15).
  • • Bound to MISMO data point ExecutionDate (%PV%) at MESSAGE/DOCUMENT_SETS/DOCUMENT_SET/DOCUMENTS/DOCUMENT/SIGNATORIES/SIGNATORY/EXECUTION/EXECUTION_DETAIL/

How to fix it

On the URAR, this lives at: Certifications → Signature → Date of Signature and Report (%PV%). 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.

The free UADCheck inspection evaluates UAD1507 automatically — attach your package and see in seconds whether it fires.
