IRIS Forms can be configured to import form contents from a data provider, such as a database or another system; this is done in the MDE Setup.
To import from a data provider, do as follows. Please note that if the Import menu is disabled, then no data providers have been configured.
Select the data provider from the Import submenu in the File menu.
IRIS Forms will suggest that possible changes to the current form contents and template settings are saved before a new one is imported.
