Incorrect Acct determination Field in AS01 Trx.

Hi Guru's.

I've created a new asset class copied from other asset class.

I've chanched the acct determination and screen layout rule by trx OAOA.

The problem is when I want create a new asset for the new asset class ( trx AS01 ).

In the field "Acct Determ" the acct determinacion isn't the new, is from the asset class wich I copied the new asset class.

How I can change this???

thanks a lot.
