Configure the Data Medium Exchange for making payments

How can I configure the Data Medium Exchange for making payments? 
How can I link it to (F110) payment program & get the file MT100 to be sent to the bank?

When configuring the payment methods for the country (transaction OBVCU), choose the payment medium program as RFFOM100. 

From se38, pls read the documentation for the program, which will give you the various options & the required config too. 

You would also need to configure the instructions keys as required. 

To generate the DME file, you have to run the automatic payment program with this payment method. 

After the payments have been successfully posted, you can go to DME administration and with the help of dme manager download files on your PC. 

SAP has determined that the standard print programs for automatic payments will no longer be supported, and will be replaced by transfer structures created by a tool called the DME Engine. 

This tool enables the business to create DME output files without ABAP development, and can be attached to a print program and form for the creation of Payment Advices. 

Outside of the DME Engine (DMEE), the majority of the configuration takes place within the following IMG menu path: 
IMG Path: Financial Accounting -> Accounts Receivable and Accounts Payable -> Business Transactions -> Outgoing Payments -> Automatic Outgoing Payments -> Payment Media -> Make Settings for Payment Media Formats from Payment Medium Workbench 

Config 
Assign Selection Variants 
IMG -> Financial Accounting -> Accounts Receivable and Accounts Payable -> Business Transactions -> Outgoing Payments -> Automatic Outgoing Payments -> Payment Media -> Make Settings for Payment Medium Formats from Payment Medium Workbench -> Create / Assign Selection Variants or transaction 

OBPM4..select your format that you are using 

Check in FBZP config that all is linked! 

Although this is bitty but you need to work through it! 

Start with FBZP, create all there than go to DMEE either to create your own format or use the standard ones.. than go to the menu path above and work through from create to assign...
