Samples

Transaction Rule:

Default(ClientState, Previous());

If, for instance, the user types in 'SUSP' as the ClientState value and completes the insertion for the Transaction, the next insert screen will display 'SUSP' as the default value for ClientState, which the user may change. In other words, the default value for ClientState will be the last value entered.
