Hello annappa123,
As for today (March, 27th 2003), the highest refresh level of CATIA424 is Refresh 3. As you may know, Each new level appears with Refresh 2. This time, refresh 3 is out, so 424 is certainly the last V4 level to exist.
When transfer to lower level is mandatory (BACK function), I do not know anything but CATBACK.
Regards,
