Which legacy systems can the Enterprise Solution-Supply (ES-S) query and view orders in?

The choice identifies the appropriate legacy systems that the Enterprise Solution-Supply (ES-S) can interact with to query and view orders. Recognizing that the ES-S is designed to integrate with multiple systems for enhanced supply chain management is key to understanding this.

The correct answer highlights three specific legacy systems: the Materiel Management System, D035A, and D035K. The Materiel Management System is crucial as it provides overarching management of all supply chain processes, making it essential for order tracking and management. Meanwhile, D035A and D035K refer to specific Defense Logistics Agency systems that contain procurement and supply chain data; these systems are integral to supporting logistics and materiel management operations across services.

Leveraging data from these systems provides the ES-S with the capability to offer a comprehensive view of orders, helping users make informed decisions based on real-time data. This integration underscores the importance of legacy systems in modern supply chain logistics, serving as a backbone for effective operations.

Understanding this connectivity is vital for efficiently managing supply chain requirements, making the selection of these systems relevant and logical for effective query and order viewing capabilities.
