Introduction to SAP eWM

SAP eWM is a logistics software that’s designed to manage and optimize warehouse operations. It’s part of the SAP Supply Chain Management (SCM) suite and provides a comprehensive set of tools for managing inventory, processing orders, and tracking shipments. SAP eWM is used by companies of all sizes, from small businesses to large enterprises, to streamline their warehouse processes and reduce costs.

What are SAP eWM Tables?

SAP eWM tables are database tables that store information related to warehouse operations. They’re used to store data such as product information, stock levels, orders, and shipments. These tables can be accessed and manipulated through the SAP eWM user interface or through custom programs and reports.

SAP eWM Table Categories

There are four categories of SAP eWM tables: basic tables, process-specific tables, cross-process tables, and customizing tables.

Basic Tables

Basic tables are the most fundamental tables in SAP eWM. They store information that’s used across multiple warehouse processes, such as product master data, storage bin data, and unit of measure data.

Process-Specific Tables

Process-specific tables store data that’s specific to a particular warehouse process. For example, the /SCWM/PRDI table stores product data for inbound and outbound deliveries, while the /SCWM/GR table stores data for goods receipts.

Cross-Process Tables

Cross-process tables store data that’s used across multiple warehouse processes but isn’t included in the basic tables. These tables are often used to store temporary data or to bridge information between different processes.

Customizing Tables

Customizing tables are used to store configuration settings for SAP eWM. These tables are often used by system administrators to customize the behavior of the system.

SAP eWM Table Examples

Let’s take a closer look at some examples of SAP eWM tables and how they’re used in the system.

/SCWM/PRDI – Product Master Data

The /SCWM/PRDI table stores product master data, such as product descriptions, weight, and volume. This table is used by various warehouse processes, such as inbound and outbound deliveries, to retrieve product information.

/SCWM/STO – Stock Overview

The /SCWM/STO table stores information about stock levels in the warehouse. It includes data such as the quantity of stock in a particular storage bin and the date and time of the last stock count.

/SCWM/RFUI – Radio Frequency User Interface

The /SCWM/RFUI table stores data related to the radio frequency (RF) user interface.

The /SCWM/RFUI table is used to store information such as the RF device used, the user ID, and the date and time of the transaction. This table is especially useful for companies that use handheld scanners or other mobile devices to manage their warehouse operations.

/SCWM/TOR – Transfer Order

The /SCWM/TOR table stores data related to transfer orders, which are used to move goods between storage bins or between warehouses. This table includes information such as the source and destination storage bins, the quantity of goods being transferred, and the date and time of the transfer.

How to Access SAP eWM Tables

SAP eWM tables can be accessed through the SAP eWM user interface or through custom programs and reports. To access the tables through the user interface, users can navigate to the relevant transaction codes or menus. Custom programs and reports can be developed using programming languages such as ABAP or Java.
