SAP EWM (Extended Warehouse Management) is an automated warehouse management system built by the German company SAP. 

SAP is an IT company specialising in software for medium-sized and large organisations all over the world. It was founded by five former IBM employees back in 1976. The ERP system they created in the 1990s became the most popular one worldwide and brought the company great recognition and profit. Its market capitalisation runs into tens of billions of euros.

Warehouse management systems are one of SAP's business areas. Their key product in this segment is SAP EWM. It came into the world in 2005 as a separate, standalone application, continuing the development of the SAP WM module that was part of SAP ERP. Every year SAP has refined the system to match the current needs of the market. At the moment it is tacitly acknowledged as the most functionally complete WMS system in existence. The core functionality of SAP EWM is shown in the picture:

In Russia SAP EWM has been chosen by such large companies as Eldorado, Lenta, Enter, Ferrero, Utkonos, OMPK, Detsky Mir, Hochland and Bezant.

SAP keeps improving the system to match changing market conditions. A new release with additional functions comes out steadily, roughly every six months.  In late 2014 the SAP EWM Customer Influence project was also launched. Under this project, customers, partners and other interested parties can submit requests for additional features in future releases of the system. It is safe to say that SAP is persistently trying to extend its reach and take first place in the WMS market.  

This article is about the automatic creation of packaging items. The option appeared in release 9.1. The feature is very useful if the warehouse uses packaging materials whose consumption has to be tracked.

This article is about a concept and an object in SAP EWM called the availability group. To be honest, I would have put the availability group in the organizational structure section, but SAP itself assigned it to the goods receipt processes. To understand what an availability group in EWM is, you first need to understand the organizational structure of SAP ERP.

The consolidation group in SAP EWM is used in outbound processes to determine which delivery items may be packed together into one handling unit.

In this note I list the ABAP objects in SAP EWM that are useful when debugging PPF.

This note lists the ABAP objects that come in handy when debugging RF transactions.

In this article I describe what the standard SAP EWM exception codes ADPR, BIDP, BIDF, BIDU, BFRP and BPRP are for.

Continuing the description of what the standard SAP EWM exception codes are for. Today we look at CHBA, CHHU, CRID, CUOM and CUO2.

The exception codes DIFC, DIFD, DIFE, DIFH, DIFP, DIFS and DIFW are used to confirm a warehouse task with a reference to a delivery with a smaller (or, less often, a larger) quantity. What is the difference between them?

In this article I describe a new piece of functionality in wave management, namely the automatic retry of wave release. 

In this article I describe a new option that had been sorely missing. It is about changing the stock type of stock sitting in the Difference Analyzer.

In this article I describe the option of confirming the movement of several handling units to one storage bin collectively.

In transaction /SCWM/MON, the nodes dealing with stock and handling units can now show the higher-level HU and the highest-level HU. This is very convenient, because SAP allows handling units to be built at various levels, but until now there was no way to follow that structure in the monitor.

About a year ago one more SAP product – EWM – was included in the SAP Influence program. The idea behind the program is simple: any user of the system, customer or partner, can submit a request to change functionality, publicly visible on the portal. Registered users of that portal can vote for the requests they like. The requests that collect the most votes are implemented by SAP in one of the following releases. The first package of changes has been implemented and released to the public in the form of SAP Notes. They can also be installed all at once by applying a support package.

В данной статье я расскажу про новую функциональность в управлении волнами, а именно – автоматическое повторное деблокирование волны. 

В транзакции /scwm/mon в ветках, относящихся к запасу и ЕО появилась возможность видеть вышестоящую ЕО и ЕО самого верхнего уровня. Это очень удобно, так как SAP позволяет делать ЕО различного уровня, но в мониторе раньше структуру отследить было невозможно.

В данной статье я расскажу о новой возможности, которой раньше сильно не хватало. Речь пойдет о изменении вида запаса для стока, находящегося в Difference Analyzer.

Примерно год назад в программу SAP Influence был включен еще один продукт SAP - EWM. Суть программы проста – любой пользователь системы (клиент или партнер) может внести запрос на изменение функциональности в общем доступе на портале. Зарегистрированные пользователи данного портала могут голосовать за понравившийся запрос. Те запросы, которые набрали максимальное количество голосов, SAP реализует в одном из последующих релизов. Первый пакет изменений был реализован и представлен общественности в виде нот. Также можно установить их все разом, обновив service pack.

В данной статье я расскажу про возможность сводного подтверждения перемещения некольких ЕО в одно складское место.

Most warehouses are unique and have a structure of their own. That structure has to be reflected in SAP EWM accordingly. For this purpose SAP EWM provides such concepts and objects as Warehouse Number, Storage Type, Storage Section, Storage Bin, Quant and Activity Area. As a hierarchy they can be shown as follows:
