Summary of the Monthly Activity Transmission (Mat) User's Guide

Information by State  Print version

The MAT User's Guide is published to assist you in complying with the TRACS Automation Rule mandated by HUD in 1994. The Rule requires electronic submission of tenant and financial data by owners of certain subsidized multifamily projects and by the public agencies that administer the assistance contracts for HUD.

The MAT User's Guide is a technical user's guide describing the prescribed format MAT record layouts, field characteristics, and HUD-form data locations for all Tenant Rental Assistance Certification System (TRACS) data transmitted to and from HUD.

The MAT is a front-end subsystem to TRACS. It accepts data transmitted from the Industry sites to HUD Headquarters in an electronic form and returns messages from HUD Headquarters to sender sites. Limited edits are performed on the data format before passing the pre-validated data to the TRACS system for further validation and processing. Data which fail the MAT edits cause an error message requesting correction to be sent to the sender. The Industry members are responsible for formatting their automated data to be accepted by the MAT.

The Industry transmits MAT data to TRACS through an electronic mailbox. Transmissions not received--or received garbled--will be resolved by the participant and the mailbox carrier. This document provides the information necessary to understand the MAT requirements, prepare and transmit data, and respond to error messages returned by TRACS.
