sales order Archieve - Restore

what is the use of Restore function in the Sales order Archieve ?

I tried and could not find the function use .

Please share your experience .

In short - you may:

  1. activate archivation (in Sales Setup) of different versions of the same still unposted SO/SQ,
  2. use SO(SQ) / Functions / Archive document before changing something

say Customer cant decide on Items &| Qties, then quickly restore it to earlier version, when he suddenly says let’s return to last Friday’s variant [:)]

However, haven’t ever see someone using this functionality in real life…
