The DMEE format tree can be used by a calling application to generate a DME file. The system currently supports the use of the DME Engine from three Financial Accounting applications: payment program, tax reporting, and withholding tax reporting.

For the PAYM tree type, the format tree must be defined as a payment medium format in Customizing for Payment Medium Formats for the Payment Medium Workbench.

The calling application carries out the following steps:

1. Selects data and fills the transfer structure
2. Calls DMEE modules with the data that has been selected
3. Obtains an internal table with data in format structure
4. Writes data to a file or to File/TemSe/... and, in the case of PAYM, possibly updates DME administration
