sigma//Store, DEWAS III and SiSu (Store Integration of Subsystems) for organisations with ERP-systems.

In the following scenarios have been realised in a great variety of projects. The range of application and the environment in the store are defined by the organisation of the enterprise.

Szenario A

  • ERP-system as the central merchandise management system
  • sigma//Store resp. DEWAS III as store merchandise system or local merchandise system of an independent retailer.

Szenario B

  • ERP-system as a central merchandise system, that also covers the store merchandise management
  • SiSu for the control of store processes and the peripheral equipment in the store.
  • sigma//Store resp. DEWAS III as the store merchandise system or local merchandise system of an independent retailer.

Scenario A – sigma//Store resp. DEWAS III as a merchandise management system

With sigma//Store resp. DEWAS III as a store merchandise management system gives flexibility to organise the local processes independently from the central merchandise system. The control of the peripheral equipment is integrated and transparent to the central system.
All merchandise management processes in the store including stock keeping will be handled completely. A clear division of labour is set between store and central system. The supply of data is secured by the ERP-system, This comprises master data of the products, including suppliers, linkage of product codes and price changes. Also electronic delivery notes originating from the central MMS resp. from the supplier are processed. The store MMS keeps the stock on hand and can evaluate all movements of merchandise by buying and selling prices.

Local system like PDT's, scales, cash registers, label printers etc. are controlled by DEWAS III via sigma//Store or DEWAS III The ordering functions create orders, either by automatic re-ordering or with order proposals, that are sent to the central system or directly to the supplier. DEWAS III collects all movements and transfers this information as single transaction with product and EAN details or if configured differently, as a summary at the level of departments and sub-departments to the central system. All stock on hand figures including product movements are stored by transaction.

sigma//Store as a central store MMS capable to handle concessionaires, is a further advantage of linkage to a central system using current technologies like e.g. direct database synchronisation.

Scenario B – SiSu for supporting the central MMS

The merchandise processes are mainly run by the central MMS and ERP-system.

SiSu - (Store integration of Subsystems) serves as a local front end in order to optimise store processes and the control of the peripheral equipment.
SiSu takes care of the peripherals and secures the data exchange with these devices. This means for retail enterprises that local data transfers are standardised and can be bundled.

SiSu also handles scheduled price changes and activations, printing of shelf labels, poster printing. It also provides important reports on price changes, new or terminated products, etc.

In case communication lines are down SiSu can execute local price changes. In this way 'emergency price changes' can be made. Also special prices for e.g. perishable products where the 'best before' dates are almost reached are possible in offline situations.

Operative functions like support for ordering, registration of other movements and stock taking with the use of PDT's are possible with SiSu. Since SiSu has its own local database, important pre-checks of the data prepared to be sent to the central system can be made. Also validity checking of manually entered data can be done. The resulting data is sent to the ERP-system, merchandise data as well as financial information for further processing. Also in this configuration, sigma//Store resp. DEWAS III installed at an independent retailer who gets supplied from the same central can be attached.

Connection to an ERP-system

sigma//Store, DEWAS III and SiSu communicate where possible directly with the central MMS. i.e. via interfaces provided by the central system. Since we have an open interface concept, we can integrate easily external interfaces.

As far as e.g. SAP is concerned converters resp. data mapping is no longer necessary. SAP IDOCS from can be processed directly. Also SP-Retail can be connected via IDOCS. Data loss in either direction is therefore no problem. Efforts for adaptation are reduced to a minimum. SAP architecture PDM Pos Data Management is completely supported. Data models are matched with SAP-Retail so all special cases in the retail business from different selling units, empties, display stands, set products, calibrated merchandise, service departments etc. are covered.
