The system uses standard EDI eCommerce functions to select the external payment files from the location on your network where they are stored, and to save them as Financials payment files for processing.

Payment file extensions are mapped to their correct EC (Electronic Commerce) subsystem in EC Subsystem Definition Maintenance (35.13.1). The subsystem in this case is the external banking system in which the file originated. Defining the file extension here ensures that the system associates the payment file with the correct external module. These mappings are preconfigured and do not require user input.
