Dear Team,
Currently - On Account ,Yes and No both of the radio buttons are disabled when user is not allowed for Advance payment .
In this case End user unable to identify the disabled mode of the buttons and clueless that what needs to be done next to continue since there is no response from system .
It would be better if system gives a prompt message when user trying the to select the On account Yes and its not allowed on his/her Profile.
Warm Regards,
R.Kanagaramu
