Database updates without end transaction

Hi,
We are using Natural for Aix(4.3), Natural for NT(ver 4.1.2) and Adabas(3.1) for NT and Unix.ALSo we are Entire network as a network protocol.
While programming using Natural and trying to update Adabas database. Record is committing withoutend transaction. Tried to change parameters for natural configuration utility but still didnt work. I believe either Natural or ENtire net work is doing End transaction. If anyone got this problem and solved please let me know.
Thanks
