The EDI ports are defined in AlphaPro: Exchange & System -> Serial Ports.

  • The input message must have a termination character
  • Maximum 128 characters. If longer strings, the first 128 characters will be returned, the rest will be ignored.
  • Parsing the content is done in the action string in the Event Handler

Event description

Event Owner: EDI Text Config
Event type: 28 - External Data Input
Subevent: 1 – 10: specifies which EDI port
0: matches all ports
When change to ON: When valid data is received on EDI port
When change to OFF: N/A
When related to: N/A


Additional information

  • Context parameters
- %edi is the input text where termination character is excluded
- %sev is the EDI port (sub-event)
  • Useful macros and statements
  • %scutc - Extract substring by byte (character) position
  • %scutf - Extract field, fields defined by delimiter character
  • %sscan - Scan for string, extract rest of string after first match
  • %scmp - Compare strings
  • TMP - Set temporary variable
  • %tmp - Read temporary variable
Note icon The NUL character (ASCII 0x00) cannot be used in the EDI string. The processing of the string will be terminated when receiving NUL.
