SAP Product



At its factories in Mainz and Hallein (Austria), Werner & Mertz GmbH manufactures quality products for selected international markets. The production of high-quality branded cleaning products involves the use of the open software suite from SAP AG – a fact that points to the farsightedness of this traditional Mainz company. The key to this long-term sustainability in the company's IT is SAP MII: SAP Manufacturing Integration and Intelligence. With SAP MII (SAP Manufacturing Integration and Intelligence), IGZ eradicates non-SAP interfaces and subsystems from the highly-automated production processes, helping Werner & Mertz achieve maximum process transparency.

In collaboration with IGZ, all filling lines at the Mainz and Hallein (Austria) sites have been interfaced with SAP MII (SAP Manufacturing Integration and Intelligence), so as to significantly reduce the subsystem architecture. The result: an optimum boost to efficiency, maximum plant availability and outstanding quality.

Werner & Mertz GmbH is a German household chemicals company based in Mainz, Germany. The core competencies of the Mainz-based chemicals company focus on cleaning, upkeep and preservation. Members of the company's comprehensive product portfolio for cleaning and upkeep include  the familiar brands of Erdal, Frosch, Emsal, ratzfatz and tana.

Cleaners and detergents are manufactured at Werner & Mertz's Mainz facility, while small-batch and specialist products are produced in Hallein, near Salzburg. Strong brands, highly-qualified and motivated employees and the all-encompassing focus on environmental friendliness are the key aspects of corporate policy. Every year, the company manufactures a total of 171 million items.

For a European market and innovation leader in specialist detergents, a long look behind the scenes at the production processes is essential to bring to light hidden productivity and quality potential and manage it in a targeted manner. As part of comprehensive IT consolidation at Werner & Mertz, the strategic approach was to map the vast majority of production processes in SAP MII (SAP Manufacturing Integration and Intelligence).

Overall, 16 automated manufacturing lines – each comprising up to 12 pieces of machinery – as well as four autonomous manufacturing lines and a further seven manual lines at the two production sites in Mainz and Hallein (Austria) came under the control of SAP MII (SAP Manufacturing Integration and Intelligence). The overall package now consists of further automated palletisers connected to SAP MII (SAP Manufacturing Integration and Intelligence), automated labelling systems for receptacles, cartons and pallets, and the interface linking the conveyor system to the automated high-bay warehouse area and manual warehouse areas, via SAP MII (SAP Manufacturing Integration and Intelligence) identification points. Accordingly, the SAP MII (SAP Manufacturing Integration and Intelligence) Content functionality thus covers all of the areas from process control through to shop-floor controlling and machine interfacing.
