Insert Account Assignment catagory and it dependent value

Hi Experts,

I have an issue.

I am creating a transaction of service process,I have to assign the value of the account assignment group the first time and as soon as enter is pressed, it opens a new field and tht value also needs to be filled.

Any body have any idea how to do this automatically when the transaction is saved the first time.

I am trying to write the codes inside the ORDER_SAVE,but i am not getting how exactly should i do to make those entries and save.

Pls suggest something, a little in high priority at my end.

Thanks,

SA
