Creating Flat File Schemas for Internal-Format Documents
If you want to use EDI built-in services to convert internal-format documents (for example, documents from a back-end system) from IData objects to strings and vice versa, create a flat file schema that defines the structure of the internal-format documents. Use the functionality in the WmFlatFile package in Software AG Designer to create the flat file schemas. For more information, see Flat File Schema Developer’s Guide.
Note:
For backward compatibility, you can also use an IS document type to define the structure of internal-format documents. However, Software AG recommends using flat file schemas.
