# ST-DBP-007 - Multiple Flowchart Layers

> **Rule ID**: `ST-DBP-007`

**Rule ID**: `ST-DBP-007`

**Scope**: Workflow

## Description

The rule checks whether flowcharts are used as a top layer for maintainability and readability reasons.

## Recommendation

It is recommended to reduce the number of flowchart layers to a minimum to ensure maintainability and readability.

## Modifying the Rule

In the **Project Settings** window, select the **Workflow Analyzer** tab. Find and select the rule, as in the image below:

The default **Layer count** value is `2`. This means that if the **Workflow Analyzer** finds at least three flowcharts, then a message is logged in the **Error List**.

Modify the value to `3` and the rule logs an error message only if the number flowcharts surpasses the threshold, in this case `3`.

## Reset to Default Value

The default value for ST-DBP-007 is `2`.

To reset the value to default right-click the rule in the **Project Settings** window, and then click **Reset to default**.
