MAN Truck & Bus AG

In the MAN project POWER, we are currently changing the management of our European production chain completely to SAP. For this purpose, among other things, the entire current, very heterogeneous systems landscape of our plants is migrated to the SAP Automotive standard.

Until recently, this had required more than 150 programs and migration scripts. Most of them we can now replace with a single program - namely SimDia² - and thus strongly simplify our processes.

Since SimDia² is really easy to learn and use, most of the migration preparations can now be completed by the respective departments in a short amount of time. This saves each plant almost 2 months of project duration. Overall, more than 6 months."

Olcay Yildirim, Head of subproject POWER

Städtisches Klinikum München GmbH
Munich Municipal Hospital Group

„At the Munich Municipal Hospital, we have a very broad spectrum of SAP applications: Clinical System, Purchasing, Technology, Real Estate Management RE-FX, and certainly still more areas in the future.

SimDia² is met with great response both in IT and the responsible departments. Finally, the departments have a tool at hand that enables them to create and edit large amounts of data easily, quickly and securely. The IT department is thus relieved of routine tasks and gains more time for "cutting down trees" - i.e. for the design and optimization of processes.

Support is exemplary as well. ERSAsoft really still takes care of its customers in a personal way.“

Peter Zimmermann, Department Technology Management

BVK - Bayerische Versorgungskammer
Bavarian chamber for social benefits and pensions

"We are currently using SimDia² in property management (SAP RE) as well as in the area of SAP Controlling. Additional areas of application are currently being considered.

A big praise goes to the support. Not only before, but also after purchasing the software, you will find immediate help - here the customer is really still king; something you unfortunately hardly ever find today."

Personal Partner Strixner GmbH

"As a medium sized BPO specialist in HR, we can and will not afford spending time tailoring our software platforms - especially SAP - to our requirements. We are therefore glad to have found a competent and flexible partner in ERSAsoft, who enables us to simplify work with SAP without extensive time and financial investment.

With the help of our SimDia², our employees are now in a position to import any amount of data automatically into SAP. Due to the ease of use, this is profitable even with the smallest amounts of data. For we can not only reduce the time required drastically. Data quality increases as well, since transmission errors can no longer occur.

For us and especially for our customers, the use of SimDia² is only beneficial: Our experts are relieved of routine work and we can offer our customers a much faster and better service. "

"With SimDia², we can import and maintain thousands of entries of master data in our SAP systems in no time and without writing a single line of code. Also the overall design simply fits: From installation to first data import, our employees need no more than five minutes.

We were particularly impressed with the integrated recording assistant. With it, the creation of an import template is really only a matter of seconds. This is how software has to be: Simple and efficient "
