Payment file in IDOC

Hello There,

I am working for a client, where we are processing payments in wires, ACH and Checks. For ACH and Wire's we are using IDOC's. We are also using check printing functionality from Bank (so Bank will print our checks). We agreed that, we will be sending Idocs for check printing process to bank.

Can any one of you shed some light on how to create an Idoc for processing check payments at bank.

In Payment Methods configuration, I configured payment method classification as Check and using Payment Medium WorkBench to use ACH Format (Idoc). This is not creating checks not asking me check lot details.

Can we use a standard functionality to create checks and send Idoc to bank?

Thanks for helping me on this
