7. Save and the error is given.

Once a GL account has a posting made to it then it is not possible to change the account assignment in the accounts determination.

A possible work around is to create new asset classes, with a newly configured accounts determination assigned, and to transfer the assets to the newly created asset classes. 
It would be advised that this is test on the Q system, with the results analyzed before trying on P system.
