The Business Challenge

A leading North American plumbing supply manufacturer was struggling to create the real time supply chain visibility between ERP, suppliers, distributors and customers.
Significant post-PO (purchase order) visibility gaps plagued the manufacturer, exacerbated by delayed partner communications that forced manual ERP updates. Cost barriers prevented leveraging SAP for supplier portal collaboration. Critically, integrating SAP with the disparate systems used by distribution partners across regional DCs proved unviable due to complexity and expense, creating major operational bottlenecks.
This limited supply chain visibility manifested in several key challenges including Inaccurate Demand Forecasting, Supplier Lead Time Variability, Missed Delivery SLAs (OTIF), Lost Sales Opportunities, and Increased Inventory Holding Costs.
The organization sought a solution to gain end-to-end supply chain visibility, improve communication with suppliers, and proactively manage production schedules to mitigate these issues.
Solution Implemented
Karolium team partnered with the manufacturing company to implement a solution that leveraged existing SAP infrastructure and integrated it with supplier partner portals via secure APIs. The solution focused on providing:
