Rotarex Cuts Material Creation Lead Time by Up to 20 Days with SAP MDG

First Alluvion focused on the critical areas that were blocking delivery. A rapid assessment and technical audit kicked off this project and the goal was simple: create clarity on the current MDG setup, identify the most urgent risks and bottlenecks, understand where custom developments were causing friction. A close collaboration with the Rotarex team was established through workshops, desk research, and on-site handover sessions. During that phase, critical production issues were already resolved and once the most critical problems were stabilized, the focus shifted. Rotarex did not just want to fix what was broken. They also wanted to improve the way their MDG processes worked, especially when it came to automation. 

One of the biggest operational pain points for Rotarex was the time it took to fully create a material. After the initial request from R&D, the process still had to pass through several follow-up change requests for planning, purchasing, sales, quality, storage and warehouse, and accounting. For each plant, additional work could be triggered often across different countries, and each team had its own priorities. This created delays, increased dependency on different departments in different countries, and made the process vulnerable to manual errors. Instead of focusing on approval and data quality, users were spending too much time on repetitive data entry. 

Together with Rotarex, Alluvion tackled this in two connected ways. First, Alluvion’s return-to-standard and keep-the-core-clean mindset was used to reduce dependency on custom logic and create a more maintainable foundation. The Rotarex audit material showed that custom code and Z-tables were deeply embedded in the MDG setup, creating a risk for maintenance, testing, and future upgrades.   

Second, a rule-based automation was introduced by translating Rotarex’ business rules into flexible BRF+ decision tables, much of the required data is automatically populated. Just as importantly, several follow-up workflow steps that were previously handled manually could now be completed automatically. This reduced manual input, improved consistency, and added more proactive checks and validations in the process to reduce erroneous data creation. Instead of spending time on repetitive administrative work, the business and MDG team can now focus more on the exceptions and decisions that actually require their  input.  

Additionally, the Rotarex MDG team now has full control of their own system and is able to translate new business requirements into actual derivations themselves. 

The result of this project was not just a cleaner setup, but a much more efficient process. Other benefits of the MDG automation are:
