Challenge
Lagardère processed orders, delivery notes and invoices manually. They needed to switch to EDI communication with suppliers within their ERP, but lacked clarity on data mapping between systems and how to set up the process.
Manual processing of orders, delivery notes and invoices
Integration of the existing ERP with EDI platform
Different data structures between the ERP and EDI standards
No process for onboarding new suppliers
Unclear validation rules and tolerances
Need for documentation for both internal team and suppliers
Solution
We walked through the entire data flow from order to invoice, mapped fields between the ERP and EDI standards and wrote a manual the client uses to gradually onboard suppliers.
Data flow analysis from order through delivery note to invoice
Field mapping between the ERP and EDI formats (ORDERS, DESADV, INVOIC)
Step-by-step manual for onboarding a new supplier
Validation rules and tolerances for each message type
Process design for testing and approving new integrations
Documentation for both internal team and suppliers
Technologies Used
Results
Client onboards suppliers using the manual independently
Detailed data structure mapping for 3 EDI message types
Clearly defined requirements on the supplier side
Foundation for gradual automation of entire chain
Fewer errors thanks to defined validation rules
Documentation reusable for future ERP changes
Impact
Lagardère has a clear process for connecting suppliers via EDI. Instead of ad-hoc solutions they follow the manual we prepared. Documentation also serves as a foundation for future ERP changes.
