What is Wave Management


EWM can combine warehouse request items and split items into waves based on criteria such as activity area, product or route.

waves can be created automatically or manually with the use of wave templates.W c


Benefit of Outbound Pick Pack Stag with Wave

  • Increase efficiency by grouping requests into waves, in line with the freight plan

  • Release pick tasks in accordance with the planned loading time for each truck

  • Increase customer satisfaction by ensuring that all orders are ready to go, when requested.

Put-away Slotting and Rearrangement

Slotting is a process in the EWM that helps to define the most suitable put-away parameters such as – storage type, section, etc. Slotting places the goods in a warehouse in the manner that provides the most optimal storage and picking of goods

combine warehouse request items and split items into Benefits of Optimizing Product Placement

  • Optimize product placement considering its characteristics as well as demand pattern

  • Increase warehouse productivity by reducing empty travel time.

  • Improve utilization of warehouse space type.

What is Slotting?

During slotting, system determines the following storage parameters and stores them in the product master:

  • Put-away control Indicator

  • Maximum storage in storage type

  • Storage Section Indicator

  • Storage Bin Types

What is Rearrangement?

The system compares the current storage type, storage section, and storage bin type with the optimal parameters from slotting and will propose warehouse moves to improve the position.


You can identify the most urgent stock transfers based on the following data:

  • Slotting index of the current storage bin

  • Difference between the slotting indexes of the proposed storage bin and the current storage bin

What is Replenishment?

  • Replenishment is defined as the movement of goods from the warehouse to the shipment locations. In SAP EWM, you can use predefined techniques for replenishment of storage bins. There are different replenishment control fields defined at the storage type level or storage bin level. The data for control fields can be entered manually in the system or you can use slotting process to define these fields.

  • Following are the common control fields for Replenishment −

  • Minimum stocking quantity

  • Maximum stocking quantity

  • Replenishment quantity

  • After the replenishment control data has been entered or determined, replenishment processing can begin. The replenishment control type is assigned to the storage type in Customizing. Some of the replenishment control types require additional settings in Customizing.

Stock Transfer

Stock transfer is nothing but transferring of materials from one plant to another storage location, from plant to plant, plant of company code to plant of another company code. When the stock transfer happens between plants, then the quantity changes in both plants.


Integration of EWM into Production Planning

  • Production Orders and Process Orders

  • You can use an SAP EWM system to apply the following processes to production orders and process orders:

  • Material staging

  • Confirmation of production orders and process orders

  • Cancellation of confirmation with reference to confirmation document (transactions CO13 and CORS)

  • Post processing of faulty goods issue postings (transaction COGI)

Physical Inventory Process

  • Physical Inventory is a process to count the actual shop floor quantity and compare with book entry quantity.

  • This process may plan for year wise, continuous or product specific with pre-defined time periods.

  • Physical Inventory process can be carried out for Un-restricted stock type, Quality stock, blocked stock.

  • Physical Inventory Process can be carried out using two ways :-

1. PRODUCT SPECIFIC PROCESS:-

This means wherever the product lies, it is applicable for physical count.

2. STORAGE BIN SPECIFIC PROCESS:-

This means whatever the product in the storage bins; it is applicable for physical count.


RF Framework

  • RF stands for Radio Frequency Mobile Data Entry that allows real time communication between the warehouse employees and the EWM system.

  • The RF framework supports both browser based and GUI devices to connect to the SAP system. You can create screen templates and merge them to a so-called display profile. This display profile is assigned to the presentation device.

  • The RF framework in SAP EWM system provides all the warehouse functionalities, which are −

  • Loading

  • Unloading

  • Deconsolidation

  • Put away

  • Picking

  • Packing

  • Replenishment

  • Physical inventory

Post Process Framework Action

  • The PPF is a tool for the generic execution of functions and processes. SAP EWM uses the PPF for the following purposes:

  • • Printing

  • • Communication to other systems like SAP ERP or GTS

  • • Sending XI messages

  • • Asynchronous updates between business objects within SAP EWM

  • • Execution of loosely coupled actions into the business process with the goal of having a separate application log

  • • Generic option to enable customer extensions of SAP EWM processes, especially for asynchronous processes, printing and workflow
