Create and CreateInsert
CreateInsert enables you to create a new row anywhere in the list of existing rows.
You can create a form that allows a user to enter information for a new record and then commit the record into the data source. You need to use a task flow that contains a method activity that will call the CreateInsert operation before the page with the input form is displayed. This method activity causes a blank row to be inserted into the row set. The user can populate this using a form.
