The document discusses configuring Data Medium Exchange (DME) in SAP to generate payment files in bank-specific formats. Key steps include: 1. Creating DME format trees and assigning them to payment medium formats and methods at the country level. 2. Creating variants for the payment program SAPFPAYM to specify file generation parameters and storage locations. 3. Assigning the variants to relevant company codes to generate files using the custom DME format trees for each bank.

1. Data Medium Exchange (DME) - Configuration
Relevant Acronyms:
PMW – Payment Medium Workbench
DME – Data Medium Exchange
DMEE – Date Medium Exchange Engine
Summary of Key Points:
Transaction to create DME tree: DMEE
Each DME tree must contain a Root level.
A DME tree must be activated before it can be used.
All DME Format trees for payments are driven by SAP standard program SAPFPAYM.
Each field in a DME tree is named an “Element.”
An Element’s subfield is called an “Atoms.” These atoms can be used to add additional
flexibility to a field.
There are 5 main types of attributes which can be assigned to an Element or Atom.
Constant
Structure Field
Reference Tree Node
Aggregation
Exit Module
Each node of the DME tree can contain IF statements in the form of conditions.
Data Medium Exchange: Configuration
In many instances banks in Europe and Asia Pacific do not have standard file formats and EDI
interfaces are not utilized. This was the chosen method since each of these banks requires
payments to be sent in their own unique file formats, which have not been standardized. Using
the DMEE we are able to easily create, generate, and maintain files for each of these banks
specific requirements. Below are the required steps to successfully configure the DME in
the SAP system in order to generate a payment file using the F110 transaction.
Create Payment Medium Format: SPRO
Financial Accounting New > 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 Payment
Medium Formats
In this step of the configuration the Payment medium formats need to be created for each DMEE
tree configured. The new format must contain the same name as the DMEE format tree. We
then choose the format output Payment medium Without Docs to designate only the payment file
will be generated and the type File to signal a flat file will be generated rather than an IDoc or
XML file type. Next, under Program Control, set the Mapping using DME engine indicator,
which links the format to the custom DMEE object. Last, the Company Code check box is
selected which instructs the program to create a file for each company code involved in the
payment run.

2. Assign Payment Medium Format to Payment Method at Country Level: Transaction FBZP
Financial Accounting New >Accounts Receivable and Accounts Payable> Business
Transactions> Outgoing Payments> Automatic Outgoing Payments> Payment Media> Make
Settings for Payment Medium Formats from Payment Medium Workbench> Assign Payment
Medium Format and Note to Payee to Payment Method
For each country and each payment method the Payment Medium Workbench must be
assigned. This is done by selecting the country and the corresponding payment method which
will be using the Data Medium Exchange (DME). The option button “Use Payment Medium
Workbench” is then selected and the Payment Medium Format, which was created in the
previous step and which also possesses the same name as the DME file structure is assigned in
the format field.
Create Variant: Transaction SA38
System>Services>Reporting (Enter Program)>Go to>Variants
For payment medium programs using the payment medium workbench or for the DMEE in
particular, variants must be created here rather than directly in the payment program via
transaction F110.

3. Follow the menu path or enter the transaction code and enter the program name
SAPFPAYM. This is the standard payment program which is being used in combination with
our custom file structures to generate a file in the banks specified format. Once the program
name is entered select Go to> Variants which will then display a screen where the new variant
can be named or where an existing variant can be altered. A user defined name can then be
entered and created.
Next, the standard selection screen for the program SAPFPAYM will appear where the
parameters for the file format can be entered and saved. This is where the standard program is
instructed to use a designated Payment Medium and also where to store the file generated from
the payment run. Files can be stored on the server, to a location on the user’s desktop or if left
blank they will be saved internally within a TemSe for the F110 transaction.
Also, if required dynamic selections can be entered for each variant, in which the user can select
house banks, account ids and payment methods applicable to the program.
Assign Variant: Transaction OBPM4
Financial Accounting New > 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

4. Last, the variant created previously must be assigned to the relevant company codes. The
Payment Medium Format is selected and the company codes will appear in the window to the
right. All of the company codes will appear for the given country, because earlier we assigned
this format to a specified country and payment method. When we select the file format it brings
up all the corresponding company codes for that country and payment method ombinations. The
variant that was previously created should now be assigned to the company code which will be
using the DME to generate payments.
