EDI Mapping Process – From requirements to concept

Like all other software development, we are to cover the requirements and determine the expected outputs of the EDI structures

1.  Gather the EDI input and output files requirements

  • Input EDI segments and structures for the various scenarios
  • Data mapping from the source EDI file to required EDI output files.
  • Ensure the right information is mapped to the correct segments.
  • Layouts of the mapped values e.g. for numeric values, the value to start from left-to-right positioning.

2.  Determine the data mappings’ values from the input file to outputs  files.

  • Ensure maximum nos of fields and spaces required for output files from source file’s values.  These values are the ones that need to pass back to output files.
  • Ensure correct values are mapped correctly to the output files.
  • Derive the logic to extract the required values to map to the output files
