# Make field required The purpose of the rule is to change the requirement of a field from optional to required under selected conditions. {% hint style="info" %} Fields required by the system configuration cannot be changed to non-required. This means that while an optional field can be made required, the reverse is not possible. **Limitation**: the Issue View does not support the [`setRequired`](https://developer.atlassian.com/platform/forge/apis-reference/jira-api-bridge/uiModifications/#issue-view--preview-) operation; therefore, this rule will not be applied to that view type. {% endhint %}
