Dear All,

Thank You All the answers!!!!!, it works perfectly.
I can answer only now, because I was away from my computer 2.5 days. :((((
The solution was: using the Generator key, trigger with NULL checking ,

and I have to uncheck the - computed on the server- field .?! (When it was checked, the P_CODE value incremented twice, with the good trigger, too)

Thank You again,
Bye,
Torok, Zoltan
