Walmart Purchase Order Integration with IFS ERP via Pulse API
Migrating from legacy Baan ERP to modern IFS ERP with real-time acknowledgments and end-to-end visibility into the purchase order lifecycle.
A hybrid model combining human verification with automation for operational accuracy.
Baan to IFS Migration for Walmart Integration
This case study explores the migration of the Purchase Order integration process for Walmart from the legacy Baan ERP system to the modern IFS ERP system via API. The transition aimed to modernize processes and enhance overall functionality while ensuring seamless communication between systems.
The workflow begins with receiving Purchase Orders (POs) via API, which triggers automated email notifications for manual order creation in IFS. Subsequent stages—Order Acknowledgment, Shipping Acknowledgment, and Invoice Acknowledgment—are managed automatically through the Pulse API.
Primary Objective
Enable accurate order tracking, efficient communication, and real-time acknowledgment delivery to Walmart using the Pulse API.
Hybrid Model
Combines human verification with automation, providing real-time visibility while maintaining operational accuracy.
Technical and Operational Challenges
During the transition from legacy Baan ERP to IFS ERP, several technical and operational challenges were identified that needed to be addressed.
API Rate Limits
Restrictions on API call volume affecting large order creation.
Configuration Mismatches
Rejections in IFS due to mismatched configuration or missing data.
Acknowledgment Delays
Manual order creation occasionally led to delayed acknowledgments.
Order Mismatches
Inconsistencies between Walmart's and IFS's order data caused incorrect acknowledgments.
Untimely Updates
Shipment or invoice data not being updated in IFS promptly.
Invoice Assignment Issues
Invoice numbers occasionally not assigned correctly, delaying invoice acknowledgments.
Error Handling Gaps
Silent failures or lack of detailed logging hindered troubleshooting.
These issues highlighted the need for a more robust, reliable, and scalable integration framework.
Integration Workflow Steps
A structured API-based integration workflow bridging Walmart's systems with IFS ERP, ensuring accuracy, visibility, and operational control.
Receive Purchase Order from Walmart
API receives POs from Walmart and initiates the workflow.
Automated Notification
An automated email is sent to the internal team, providing PO details for review.
Manual Order Creation in IFS
The team manually creates the purchase order in IFS, maintaining oversight and data verification.
Order Validation and Retrieval
The API checks IFS periodically to confirm order creation and retrieve valid PO data.
Order Acknowledgment
Once verified, an acknowledgment is sent to Walmart through the Pulse API confirming order processing.
Shipping Acknowledgment
When shipment data becomes available, the API validates and transmits acknowledgment updates to Walmart.
Invoice Acknowledgment
After invoicing, the API sends real-time invoice acknowledgment updates to Walmart, ensuring full visibility.
