How to Review Critical Rules and Automated Revision Requests on Mercury Network® per UAD 3.6 Updates

Overview

Mercury Network® has implemented new automated rules that run the moment an appraisal is uploaded to catch completeness and compliance issues before manual review. This system helps you identify technical errors, UAD guideline conflicts, and high-risk factors earlier in the process. You will learn how the system classifies rule failures and how to manage the resulting automated revision requests.

Understanding Appraisal Rule Types

Mercury Network® has implemented new automated rules that run when an appraisal is uploaded, the system performs several checks to ensure the file is technically sound and compliant.

The system runs several different types of rules:

Rules	Description
Basic Virus and File Validation	This is a basic virus scan and formatting check. If this fails, a Document Failed status is returned, and the vendor is asked to reupload the file.
UAD Rules for zip File	These confirm the zip file meets UAD guidelines for successful upload to the Uniform Collateral Data Portal (UCDP). If a rule fails, the order will move to a Revision - Correction Needed status, and the vendor will receive a revision request to correct the issue.
Review Rules for Compliance and Risk Factors (Investigate customers only)	Investigate customers can choose which review rules are classified as Severe. When a Severe rule is triggered upon appraisal upload, the order is automatically moved to Revision – Correction Needed, and the vendor receives a revision request to address the issue.

Automated Revision Requests

Several processes within the UAD 3.6 workflow automatically initiate revision requests to the service provider. These requests detail the specific issues that need to be addressed in the appraisal.

When an automated revision request is generated as a result of a UAD rule or Review Rule firing, both the vendor and secure user can view the revision request details in the Revision Details PDF inside the order’s document repository.

The system also generates automated revision requests when it detects a Uniform Collateral Data Portal (UCDP) fatal submission finding. UCDP fatal findings requiring appraisal modifications automatically trigger a revision request to the vendor that details the issues to be resolved.

In addition to the Revision Details PDF, Secure users can also view these requested revisions and their contents in the Investor Submission workspace. For more information, see the Investor Submission section.

Note: In the future, you can configure Mercury to consolidate vendor feedback across various rule checks to reduce the number of automated revision requests.

Overriding Severe Review Rule Firings

If an appraisal triggers a Severe review rule but a special circumstance requires the order to move forward without an appraisal update, users with the appropriate permissions can override the Severe rule. This override bypasses the required correction step, allowing the order to move forward immediately instead of remaining in Revision – Correction Needed.

Where to access Revision Requests

Revision requests are now more clearly formatted and easier to review. You can access revision requests in the following locations:

Order History Log (Legacy Forms Only).
Investor Submission section of the workspace (Secure only, and only when the revision results from a fatal finding during appraisal upload or investor submission).
Order Document Repository, where a PDF detailing the revision request will be added.

See screenshot below for example of Revisions Requests Details and Rule Descriptions.

Outcome

By reviewing these new automated rules in Mercury Network®, you are able to effectively manage automated revision requests within the workflow, which may have triggered by technical errors, UAD guideline conflicts, and high‑risk factors.
