# Manage Substrate Map Overlay Information

:lock: SubstrateMap.**ManageOverlayInformation**

## Overview

This operation is used to define and manage the Overlay Information of the **Substrate Map**.

## Setup

No specific setup is required other than to meet the preconditions of the transaction.  

## Preconditions

* The **Substrate Map** is created and is Active.

## Sequence of Steps

The **Manage Overlay Information** wizard can be called from the **Substrate Map** page within the Business Data Group. In **Views**, select **Content**, choose an Overlay, and then select the **Manage Overlay Information** button on the top ribbon. In the wizard:

1. Add as many entries as you need (select :core-static-add-sm: on the top right of the grid to add and :core-static-delete-sm: to remove), and for each Attribute provide the following information:

      * Name
      * Data Type
      * Value

    !!! info
        Each Attribute works as a way of capturing situations that occur in the workflow.  

2. Optionally, enter a comment.
3. Select **Update** to complete the transaction.
