Supply Chain Master Data Planner

Position Summary

The Supply Chain Master Data Planner is primarily responsible for the accuracy, maintenance, and governance of planning-related item master data across supported warehouses and product lines. The role processes new part and item requests, maintains planning parameters and supplying relationships, performs scheduled item-planning checks, and completes approved system updates on a requested, weekly, and quarterly basis.

As a secondary responsibility, the role provides supply-planning support for assigned items or portfolios. This includes reviewing inventory and order exceptions, supporting shortage resolution, and providing coverage during workload peaks or planner absences. The role works closely with Supply Planning, Demand Planning, Product Management, Purchasing, Operations, Customer Service, Information Technology, and other business partners.

• Maintain a clear request queue and change log, including requester, approval, effective date, completed action, and status.
• Perform routine data-quality reviews and reconcile item-planning records across warehouses, reports, and related systems.

• Participate in cross-functional reviews when item setup, sourcing, excess risk, minimum order quantity, or planning parameters require clarification.

Secondary Responsibilities

Supply Planning Support

• Provide planning support for an assigned group of shared SKUs, product lines, or customer portfolio based on team workload and business priorities.

• Assist with purchase-order, work-order, and transfer reviews for assigned items and provide backup coverage for other planners when required.
• Respond to internal inquiries regarding item availability, planning status, and supply constraints, or route the request to the responsible planner.

Continuous Improvement

• Identify opportunities to improve master-data accuracy, request turnaround time, planning stability, and cross-functional handoffs.
• Support development of data-quality measures, service-level targets, and recurring review schedules.
• Participate in system testing, process changes, and implementation activities that affect item planning or master data.
