# ST-PMG-001 - Identify Activities with Duplicate IDs

> ST-PMG-001 Workflow Analyzer rule that checks whether all activities in the project have unique idRef values to prevent duplicate ID conflicts.

**Rule ID**: `ST-PMG-001`

**Scope**: Workflow

## Description

The rule checks whether all the activities used in the project have unique idRef values.

## Recommendation

Make sure all the activities used in the project have unique IDs. Performing any change inside an activity will regenerate the idRef and give it a unique value. Analyzing the project after changing the duplicate ID results in the rule no longer being triggered:
