Payment Method Configuration

Hi Frends,

I need to Define payment methods for ACH & EFT.I am not sure what are the specification to give while configuring this one.Please help me to configure the ACH & EFT payment methods...

Note:if we use Payment Method -CHECK,,,we Run APP-F110(Normal Process).

If i use Payment method ACH/EFT/Credit Card,,,,What would be the process.I mean is there any additional steps are to be followed? or Only APP-F110? Kindly Advice me in this regard.

Thanks
