Change the captions of forms through extension
Dynamics 365 for Finance and Operations is now being licensed as Dynamics 365 Finance and Dynamics 365 Supply Chain Management. For more information about these licensing changes, see Dynamics 365 Licensing Update.
The form caption appears in the page tab next to the web browser's Address bar and helps the user identify the page that is currently open. In metadata, the form caption is represented by a property on the form design. Therefore, to change the caption, you must modify the Caption property on the form design. You can make this change through extension. Create an extension of the selected form in the extension model, and then change the Caption property as usual.
The following illustration shows what the form caption looks like in a browser.
None of the other properties on the form design can be changed.
