The Update Fields order module specifies what fields need to be updated at a certain point in the order process. Once added to your order queue, the order process will stop and update only the specified fields you have configured in the module. When the module runs, a page displays so the user can update the fields as necessary.
For example, the values stored if you want to update the name of the company in the predefined order fields are updated.and the username and password fields for the first service in the order, enter:
company
pack1[userid]
pack1[pass]
