How to change report header fields
You can change which data fields show up in a report's header area in the Report Options dialog. With a report window open, enter layout editing mode and then choose Report>Report Options or Invoice>Report Options, depending on whether you're working with a report or invoice.

In the dialog that appears, click the Header Fields radio button to highlight it. Header fields that are shown in the current layout appear in the Visible fields list on the right. Fields that are available to add to this layout are shown in the Unused fields list on the left.

To add a header field to the current layout, highlight the field name in the Unused fields list, and click Move to move it to the Visible fields list, or double-click the field name.

To remove a header field from your layout, highlight the field name in the Visible fields list and click Clear to move it to the Unused fields list.

You can also add custom header and footer fields to a report.

If you add one or more header fields to your layout, you will likely need to move them after dismissing this Report Options dialog.
