The layout concept in SAP Retail allows you to define detailed article placement information for your stores, and it interfaces to shelf optimization systems. There are several options how you can implement your layout concept in SAP Retail.

The layout concept in SAP Retail evolved over various releases. All options are still available in the SAP S/4HANA system. This means you can create a layout which comprises layout modules, and which sorts these layout modules by so-called layout areas. A layout can either be assigned to a store, or to an assortment.
Note
The latest option is to only focus on maintaining layout modules for assortments. In that case, for each general assortment, a layout module can be created.

Before release 6.0 of SAP Retail (SAP ECC), a layout was always created to group layout modules. The layout could then be assigned to a store or to a general assortment. As of release 6.0 of SAP Retail (SAP ECC) and in the SAP S/4HANA system, it is possible to create/assign a layout module instead of a layout to a general assortment. This is determined in the assortment type customizing.
An article can be assigned to one or several layout modules.
The layout modules can be assigned to one or more layouts, or they can be created/assigned directly to general assortments, depending on the customizing settings for the assortment type.
The layout can be used to determine how the assortment list is sorted.
Layout module versions are used for the assignment of articles to layout modules. This means each layout module has at least one layout module version. As each layout module version has a unique validity period (no overlaps), you can for example map seasonal changes in a shelf. Layout module versions can contain articles from different merchandise categories. An article can be assigned to several layout module versions and can also be positioned in different places on a shelf in the same layout module version. The versions allow you to plan in advance. When the planning for a layout module version is finished, you can change the status from planned to released.
When you execute listing from the Layout Workbench, the listing period of the articles corresponds to the validity period of the layout module versions to which the articles are assigned. However, a number of days lead time for listing can be defined in customizing.


Since stores generally carry thousands of articles, it can take a lot of time and effort to assign layout modules and assortments to the stores and to create the corresponding listing conditions in the system. It also takes a lot of time and effort to make changes to individual store layout modules, but this can be avoided in a lot of cases. In particular in the case of stores, the assortments of which are similar (but not identical), you can use layout module variants to greatly simplify these processes.
A layout module variant can be understood as a sort of "exception module". You always create a layout module variant for a layout module version. The variant then contains the "delta" information, that is it contains the article assignments which differ from the layout module version. This can be any number of additional and/or removed articles. The layout module variant is then assigned to the relevant stores. In that, it maps regional or store-specific variances in layout module versions. Normally, layout module variants are created for stores that differ the least from the standard assortment.
The layout module variants have the same validity period as their versions.

Space management optimizes the placement of the articles on a shelf from a business viewpoint and makes sure that the shelf space is optimally used. In this case, key figures are defined, and the position of an article should be optimized according to these key figures. This usually concerns sales data and revenue data, or the gross margin.
It is advisable to interface a space management system with SAP Retail. If there is no suitable interface for space management:
Data is maintained twice
Space management is not integrated into relevant business processes
New articles are not included in the planning process
Optimization results are not used
This interface guarantees regular data interchange and ensures that the space management program is provided with the most up-to-date data, and that space management is included in all relevant business processes.
When activities, for which space management is relevant, are carried out in SAP Retail (for example, a new article is included in the assortment and is assigned to a shelf), the interface is triggered - partly by a workflow, or automatically - which means that you are guaranteed that it is immediately taken into account in the space management program and data inconsistencies are avoided.
The optimized data can then be used again in SAP Retail, for example, in listing.
