# Set up estimation for manual metric definition

Enable or disable the estimation property to enable the use of estimated data when actual data is unavailable, using either pre-defined or custom methods in manual metric definitions.

## Before you begin

Role required: admin

## Procedure

1.  Navigate to **All** > **System Properties** > **All Properties**.

2.  Select the Metric estimation property \(sn\_esg.metric\_estimation\).

    This property is enabled by default, allowing you to add estimated data when actual data is not available. To restrict data entry to actual values only, disable this property by setting it to False.

3.  Select the **Value** filed and set it to true.

4.  Select **Update**.

    Based on your selected settings, the estimation property is configured in your system.
