A Modular (Cloud) ERP brings the necessary core functions across your lines of business in a comprehensive suite with the qualities in a modular way. There will be a Cloud ERP with flexible scope to streamline operations across organizational units in the future.
The business challenges and loosly coupled processes require a modular, composable and flexible ERP solution in the future with a smaller but clean core (e.g. for Finance) and an intelligent combination of (micro)services for other processes (e.g. Lead-to-Cash). This approach has some challenges, like a consistent document flow or an End2End monitoring of processes, but it seems to be the best option for organisations in a more complex and highly changing world. With a modular ERP there are still End2End processes for your end user. They should have the best possible UX (user experience) e.g. with a Central Fiori Launchpad (CFLP), but the processes will be supported by a set of different services.
With this solution, the way of doing integration is different from previous ones (e.g. SAP XI, PI, PO etc.):
- Instead of point to point interfaces from system A to system B, we provide a generic API that can be used by several systems
- Data, that is generated in SAP processes will by pushed in realtime by events so that it can be used by other systems instead of hiding the data in a SAP monolith
- Open industry standards (e.g. OpenAPI) are used instead or proprietary SAP formats
- Integration is an enabler of new processes and process improvements and not only a data pusher of files
