Viewing a frozen application is helpful when you need to refer back to a prior version that contains a set of definitions that should not be changed. If for some reason a change must be made to a previous version, your team administrator can unfreeze the application, make the change, and then freeze it again. When a new version of an application is required, Designer automatically freezes the application, makes a copy, and increases the version number by one. With the capability to use the Rename option, this task is very easy and quick. Select the application to be renamed and enter the new name.
Designer does the rest.
The Grant Access by Application option allows your team administrator to assign the appropriate level of access to each application in which they have administrative rights. This option is helpful if you need to grant access for a number of developers. The Grant Access by User option accomplishes the same task as the Grant Access by Application. However, this option displays a drop-down list for users and an area to grant rights to more than one application system. This option is helpful if you need to grant a specific user access to more than one application system at the same time.
