SAP S/4HANA Migration with Mendix

SAP S/4HANA is the next generation Enterprise Resource Planning (ERP) system from one of the largest independent software vendors in the world: SAP. Thousands of leading companies around the world have chosen to upgrade to SAP S/4HANA which includes all the latest capabilities and best-practices for a wide range of industries. Many other organizations will make the transitions in the next few years.

In 2017, SAP decided to offer Mendix as one of their own products named SAP Cloud Platform Rapid Application Development by Mendix. Mendix is a low-code platform which allows its users to develop custom applications using Model Driven Development instead of via traditional coding. It provides a development environment in which developers can create applications via configuration and drag and drop. According to SAP, Mendix is the preferred way to create custom functionality. 

With Mendix, you can develop purpose-built applications with deep integrations into SAP. Mendix provides out of the box connectors to create these integrations, leveraging standardized APIs thus eliminating the need for custom work on the side of SAP. These applications can be deployed to the SAP Cloud Platform with one-click deployments for the business to test the functionality. Developing custom functionality on top of SAP has never been this fast and easy.

The transition to SAP S/4HANA can provide an opportunity for a ‘Keep the core clean’ strategy.  This is important, because customizing standard systems of record will make updates and upgrades very cumbersome. Testing customized SAP systems becomes a manual task which you can’t easily automate. On top of that, customizing in core systems often takes longer than the business wants, as it is complex. ABAP-programming is a high demanding task and only a select group of developers is able to do this fast. 

Mendix on the other hand is easy to learn for a lot of people, even without an IT background. With Mendix you can develop intuitive and modern custom applications that easily integrate with SAP. At TimeSeries, we have developed dozens of applications on top of SAP for many different customers. These Mendix applications replaced for instance custom development in SAP, Excel-files or paper processes. 

Maintenance Order Management

At Mammoet, for instance, we developed a tablet application with Mendix to manage the process of maintenance orders. Mechanics walk around the yard, select a maintenance order, indicate that work is finished, add notes exactly according to the processes at Mammoet and everything is instantly updated in SAP. This application contains 25+ SAP integrations and is developed in 8 weeks. SAP has been leading to determine the process, validation and architecture used in the application. 

Customizable quotations 

TimeSeries developed a task management application to create quotations at one of the largest aluminium production companies in the world. This business is characterized by custom requirements of customers which require custom quotations. In the new application, all the required tasks and fields per department can be configured. The quotations are validated in SAP and if approved, created in SAP via an integration with Mendix.

Materials Reservation

At one of the biggest energy network operators in The Netherlands, we have developed a Materials Reservation application with SAP fully in the lead. All materials that can be reserved are retrieved from SAP and first need an availability check in SAP. If available, a material can be reserved and/or a reservation can be updated in SAP via Mendix.

Credit portal

One of the biggest conglomerates in the world, specialized in Nutrition and Materials, asked us to develop an internal Credit Portal. All customer information in this Portal is retrieved from SAP and financial information is retrieved from another system. Based on this information, credit limits can be set and/or updated which are instantly updated in SAP.   

These are just a couple of examples of customers we have helped with flexible applications on top of SAP to keep the core of SAP clean. TimeSeries has over 250 years of accumulated Mendix experience and worked with many customers to extend SAP using low-code. We are uniquely qualified to help organizations with the challenge of migrating all the custom development in order to migrate smoothly to SAP S4/HANA.
