Hi Laszlo,

The dataset it disconnected, it can on a pda as well.

When you do an update of the dataset you can catch the errors which will be
probably mostly concurrency errors (because another user has done something
with the data), and after that with a fill refill your dataset again.

You have yourself to correct the concurrency errors wherefore are events and
methods, however you have to choose yourself the method you want to use.
(Force the update, reload the dataset for the user with the new
information and let him do his work, ask the user etc etc it can be on much
different situations and therefore much different methods ).

That is one of the the reasons why it is clever to keep your dataset as
small as possible for the situation.

I hope this helps?
