add Payments means to a sales order through the DI

Hi,

Do you know how to add payment means to a Sales Order in SAP 2007? I want to add credit card information and make sure down payment are created. The process is as follows:

1- Create a Sales Order

2- Before adding the Sales Order I click the payment menas icon in SAP

3- I add teh credit card information

4- I add the sales order.

The result of it is the creation of down payment and deposit in banking.

My goal is to create the same through the DI.

Thanks!

Hector
