Interactive Product Demo Plugin

Try the SignalEDI operating flow before production

A guided sample shows how Setup Cockpit, local uploads, Signal AI checks, partner-configured routing, Fix issues, and Live Activity work together without changing live data.

Setup tab

Choose the trading partner, documents, direction, connector, and approval rules once in Setup Cockpit.

Setup

Setup Cockpit captures the trading partner, message types, direction, routing guide, and required connector before any production files move.

Configured sample: RetailMart 850 inbound + 856/810 outbound over SFTP

Optional detail: X12 segments, CSV columns, and captured document fields stay inspectable after Signal explains the business issue.

Local file and mobile upload simulator

Purchase order upload

file: retailmart-po-1042.csv
source: laptop upload
contains: PO number, buyer store, ship-to, items, dates

Simulated Signal AI result: Signal AI matched RetailMart 850 setup and picked the SFTP inbound route

Upload is a file intake step. Signal decides the processing route from the partner and message setup.

Partner-configured route preview

partner: RetailMart
message: 850 purchase order
direction: inbound
route: SFTP folder from partner setup
result: normalized order ready for operations

Saved setup

RetailMart order route

The customer saves the partner, file type, and connector once. That setup decides the route before any upload moves.

Ready to test
Partner: RetailMart
File: 850 purchase order
Route: SFTP inbox now, AS2 when RetailMart requires it

AI check

Signal checks the file and map

retailmart-po-1042.csv matches the saved RetailMart 850 setup. Signal finds one blocker: the store code is missing.

Fix Issues explains the missing store code and asks operations to add it before the file moves.

Live Activity

Current state stays obvious

Uploaded -> AI checked -> Fix Issues opened. After the blocker is fixed, the file follows the saved SFTP route.

Next action: add store code, then retry the route.
