SAP Datasphere

ABAP Source system is missing prerequisites for Data Flows and Replication Flows features.

1. Make sure to add the required resources in the Cloud Connector as per Datasphere Help page Configure Cloud Connector #3 Section d.
   Ensure there are no typos when maintaining the resources.
2. Make sure the source system fullfills the system and version requirement in SAP Note 2890171, either
   • S/4HANA On-Premise 1909 or higher
     Or
   • ABAP-based System with DMIS addon (For example, ECC or BW/4HANA or NetWeaver, such systems must have DMIS addon)
3. Upgrade SAP Cloud Connector (SCC) to the latest version, according to KBA 2539713 - Upgrade to a new version of the Cloud Connector.
