What’s happening?
The lookup reference in the header of an entity form is not rendering the modal dialog on click, instead redirecting to the referral form.
Reason:
This behavior is by design. The controls in the header are replaced with simplified versions, meaning not all control features are supported in the header. For lookup controls, only a link is rendered, and options like "Use Main Form Dialog for Edit" are not supported. Unsupported controls, including custom Power Apps Component Framework controls or web resources, won’t display in the header.
Resolution:
- To utilize the full functionality of these controls, consider adding them to the form header flyout instead of the form header.
- For further details, refer to the Microsoft documentation Configure header properties in the form designer - Power Apps | Microsoft Learn.
