  • You just need to change the requirement level.
    On the form designer double click on the field. This will show you the Field Properties where the Visible by default checkbox is.

    Click on the Details tab and then click the Edit button.

    Here you can set the Requirement Level from Business Required to No Constraint.

    Now you can hide the field from your form.

    Save and Publish your customizations.

    Your other option is using JavaScript.

    On Load of the form you could use the following:

    // Change the required level

    On Save you could use the following:

    // Set a default value
    Xrm.Page.getAttribute("subject").setValue("This is your default value");
