MDG S BRF code not getting triggered

Hi Folks,

My company recently implemented MDG S .

I tried to change the BRF derivation which was already exiting.

Original code : It is simple.

If Change request = create then Account group = EIN.

It is working.

Now i changed the same as if Change request = Create then Acccount group = ZUT.

I saved and activated.. But still this code is not getting triggered.

and the value is still populating as in Original code where account group = EIN.

Instead now it should be ZUT.

Please help where i am missing what need to be done to execute this new code.

Thanks in advance,

sspra.
