SAP Inventory Management Guide

Get to know SAP inventory management for the Materials Management (MM) module and its mobile apps included in the RFgen MobileEdge™ for SAP solution. RFgen®’s IM mobile apps suite optimizes inventory management for raw materials, work-in-progress goods, and finished goods (FG).

What is SAP Inventory Management?

SAP Inventory Management is a comprehensive tool within the SAP ERP system, designed to optimize and streamline inventory operations across various industries. It enhances the movement of inbound inventory (goods receipt), outbound inventory (goods issue), material movements, reservations of quantities to be posted, and demand planning.

How It Works

SAP Inventory Management in the MM Module works by tracking all movements of goods and maintaining updated inventory records. When goods are received, issued, or transferred within the organization, these transactions are recorded in real-time in the system.

This allows for accurate monitoring of stock levels, facilitates the planning of future procurement, and ensures efficient management of warehouse operations.

Understanding SAP Inventory Management

Mobile Inventory Applications for SAP Inventory Management (IM)

RFgen® for SAP includes mobile applications for many transactions in its SAP Inventory Management Suite, providing mobile automation for locating, issuing, and transferring materials.

Cycle Count

This functionality allows users to count materials and validate those counts directly in SAP. The process is paper-free and allows for batch- or serial-controlled inventory counts.

Delivery Signatures

Users can capture signatures directly on a mobile device during a delivery or pickup.

Issue Materials

Materials can be issued to a project with automatic deduction from quantities of source items.

Material Inquiries

Using this functionality, users can find materials, locations of materials, and material status based on the material master.


This functionality enables users to transfer material locations, assign bin numbers to existing materials, or change the material type. Materials may be transferred to other departments or sites, or labeled “in transit.”

Best Practices for SAP Inventory Management (IM)

Implementing best practices is essential to get the most out of SAP inventory management processes. Best practices include:

  • Accurate data entry. Ensure precise and timely data entry for all inventory transactions to maintain data integrity. RFgen® mobile barcoding eliminates the need for data entry by automating the data capture process with perfect accuracy.
  • Regular inventory audits. Conduct periodic physical counts and reconcile them with SAP records to identify and correct discrepancies. RFgen® can help automate cycle counts to ensure efficient, accurate inventory levels.
  • Use SAP batch tracking methods. Utilize SAP’s advanced functionalities like batch management, serial number tracking, and real-time analytics for detailed inventory tracking and reporting. RFgen® can further improve these tracking methods.
  • Optimize inventory levels. Inventory optimization techniques such as Just-In-Time (JIT) and Economic Order Quantity (EOQ) can help balance stock availability with cost control. Leverage RFgen® automation to prevent stock-outs and automate replenishment.
  • Conduct regular training and knowledge sharing. Regularly train staff on SAP inventory management processes and encourage knowledge sharing to improve system utilization and efficiency. RFgen® can reduce training requirements by as much as 80%.
  • Continuous Process improvement. Regularly review and refine inventory processes, incorporating feedback and leveraging new SAP updates and features, as well as data collected with RFgen®.
  • Leverage data insights. Use collected data to analyze trends and chokepoints. Predictive analytics tools can be helpful in forecasting demand by proactively planning for necessary inventory levels. RFgen® includes a configurable live visual dashboard for key metrics.

Future Development of SAP IM

While the basics of inventory management are expected to remain consistent for years to come, the most significant changes will come from the integration of additional technologies. SAP Inventory Management is expected to be increasingly driven by advancements in IoT (Internet of Things), AI (Artificial Intelligence), and machine learning.

Developments in these technologies will enable more automated, predictive, and real-time inventory tracking and management, enhancing accuracy and efficiency. Integration with cloud-based platforms and mobile solutions will also provide greater flexibility and accessibility, allowing for more dynamic inventory control and decision-making.
