Storage Control in SAP Extended Warehouse Management explained

Category: SAP EWM Posted:May 07, 2020 By: Ashley Morrison

The principle of Storage space Control in SAP EWM is very vital and also essential. This is the driving source for a product in a stockroom where complex movements with complex layout structures exist. This article speaks about storage control simply and practically.

A complicated storage warehouse is bound to follow specific processes and steps along with a physical design to get goods to issue items. SAP EWM has arrived with 2 types of storage space control one is process-oriented and another one is layout-oriented storage control.

In most storage facilities the items putaway will not go directly to the last location bin. The HU/items will certainly follow the multi-staging physical movement. Also, things will certainly adhere to some processes with steps. In the Inbound process, the pallets or case HU’s can be organized at factor or stage and if required consolidate or putaway from hosting. In many cases, two hostings are required to put away to the final destination bin. This putaway hosting can be set up with Layout-oriented storage control.

In the Outbound procedure after choosing the items relocated to pack terminal consolidation and finally move to deliver lanes and packed into trailers. The physical motions of HU’s via conveyor can be set up via process-oriented storage control (POSC) along with Layout Oriented Storage Space Control (LOSC).

Process-oriented Storage Control (POSC)

The activity of items in a storehouse is based upon processing requests.

This is readily available for items in HU’s. Non-HU managed items are not supported.

Inbound procedure actions are predefined by SAP and can not be transformed.

Configuration steps in Process-oriented:

Specify Storage procedures like inbound process (default ex: INB1) as well as an Outbound procedure (default-OUT1).

Outbound process action connecting to SAP standard inbound process steps.

Appoint external process STEPS with series to Storage space procedure.

In a Process-oriented storage space control area, you can also regulate the Destination area and WPT resolution.

The resolution storage procedure starts with the resolution Storage facility procedure type. The Whse process type determines with fields Shipment doctype, item type, priority, and process type indication in the master data for item Whse data field.

Settings for storage space procedures are important.

Establish the storage procedure (ex-spouse: INB1) in the Storage facility process type (1011) for the Goods receipt procedure.

Set the Storage procedure (ex: OMDX) in the Storehouse Order production guideline (ex: OMDX) for the Goods Issue process.

Layout-oriented Storage Control (LOSC)

Item does not travel directly from source storage space place to location storage space, yet relocation using intermediate area is called staging locations.


Hu’s are not needed in Layout oriented storage space control if choice and ID factors are made use of. You specify intermediate storage containers. These bins can be utilized as identification points in order.

Making use of both procedure and design-oriented storage space control

EWM constantly implements the procedure-oriented storage space control initially. The Layout-oriented storage control after that checks whether the series of process steps are possible in format view.

An action can be executed in a single level basis or Multi-level basis through intermediate storage space types.

The below two diagrams explains the direct storage control and multi-storage control in SAP EWM.

The outbound scenario for storage procedure control

Let’s take 2 company scenarios:

1) Outbound with packing -pick, pack, stag, and also load.

2) Outbound with Stag– pick, stag, and tons (no packaging here).

So we need to develop two custom storage processes called OUTS as well as OUTP as below.

and creating external actions as well as connect them to suitable basic internal actions as below.


Now appoint external storage procedure steps in series to customized storage refines OUTP and also OUTS as below.

If you desire an intermediate phase for the process-oriented after that we can set up layout oriented as below.

Finally, the triggering point of outbound storage space process is from WO (WOCR) setup as below

Inbound scenarios for storage space process control

Let’s consider 2 companies

1) Inbound with a pack as well as put away.

2) Inbound with Dcon as well as put away.

We need to develop two customized storage processes for inbound as listed below.

We need to create an external storage process step connecting to the inner process action as below.

We need to appoint external steps in sequence as revealed listed below.

If needed for DECON and PACK we appoint storehouse process types as below.

Currently, the triggering factor for Incoming storage space procedure is from warehouse procedure type WPT as shown below.
