What is Data Quality Module
Data Quality Module (DQM) helps quickly find discrepancies and errors in your project data.
This module contains two different user rights settings on the User Rights page: one setting for creating/editing custom rules, and one for executing rules.
Pre-defined Rules
To pull up the list of rules, click on "Data Quality" in the left margin (circled in red below)
There are 8 pre-defined rules. They cannot be modified, reordered, or removed.
To find discrepancies for a given rule, click the Execute button next to it, or click the "All", "All except A&B", or "All custom" buttons to file multiple rules at once.
Custom Rules
Custom Rules can include mathematical operations and also advance functions to provide you with a great amount of power for validating your project data.

The project variable names may be used in rule logic by placing the variable name inside square brackets [].
Data Quality rules must always result with a TRUE or FALSE condition and NEVER a value.
