Hi all !

I'm trying to improve my sistems, and I've seen that incremental key fields
is one of my dificults..

1 - I need to show the number when the user click in "insert". ( 344)
2 - The user can change this number
3 - A second user will insert the next record before the first save. (345)
4 - If the first user cancel the record, the next record need to be the same
number of the first insert. (344)

How can I do it better ?
What the best way to control all it ?

Thanks !
