Ok i understand all your points... thanx

Now then i want to know wich is the right way to code a billing
sequential with no duplicates for any of the user using my system at
the same time instead of using a generator for each kind of
movement...

There is a code segment or sample that could i see for that ???

Thanx for all your support... but any way the disconection error in
my IBO Application in this case keeps worrying me... any body has a
tip about it ???

Best Regards
