As a crucial supply chain component, warehouses rely on technology to ensure seamless, rapid, and efficient operations. For many, an Extended warehouse management system (EWM) is command central—  the essential machinery to facilitate this objective. 

And when it comes to EWM, making the right choice can significantly impact the efficiency and productivity of your operations. While different types of EAM are available in the market to meet the diverse needs of warehouses, choosing the right one for your business can be challenging if the differences are unclear.  

SAP ITS Mobile and Crave RF-EWM Native App are two prominent options in the market, each offering unique features and capabilities. However, determining which solution best suits your organization’s needs requires careful consideration. It’s easy to become overwhelmed without the proper information. The decision can be simplified with a few fundamental questions!

Decoding EWM Solutions: SAP ITS Mobile vs. Crave InfoTech's RF EWM Mobile App

First, it’s important to understand the difference between ITS Mobile and RF EWM App. To begin with, ITS Mobile is a technology developed by SAP that connects mobile devices to SAP systems. It uses SAP’s proprietary Dynpro language to provide browser-based access to various SAP enterprise applications, such as ERP and SRM. If you’re familiar with editing the Config.xml and HTML files of Enterprise Browser (EB) apps, you can customize ITSmobile to work with these SAP backend applications. 

On the other hand, Crave InfoTech’s RF-EWM App, as the name suggests, is a modern mobile application specifically designed for warehouse management. It seamlessly integrates with SAP ECC and S/4 on-premise and is fully prepared for S/4 cloud integration. Powered by SAP MDK BTP, it offers a cross-platform, low-code development platform that supports multiple devices. This means you can enjoy an enhanced user interface, easy UI customization, and developer-friendly low-code JavaScript development. With a metadata-driven and low-maintenance approach, pushing code is effortless without modifying client packages or dealing with versioning. Leveraging the standard SAP EWM OData API, it brings backend enhancements through BAdIs and UI enhancements with the MDK code editor. Supporting both oData API 2.0 and 4.0, it ensures seamless compatibility. Moreover, it’s lightweight, high-performing, and reduces server load, boosting efficiency in your warehouse operations.

Its outdated interface, reliance on older versions of  HTML, and compatibility limitations create issues like lag and connectivity problems. That’s where Crave RF-EWM comes in.
