Cause

ABAP Source system is missing prerequisites for Data Flows and Replication Flows features.https://launchpad.support.sap.com/#/notes/2890171https://launchpad.support.sap.com/#/notes/2890171

    • RFC_FUNCTION_SEARCH
    • RFC_GET_FUNCTION_INTERFACE
    • LTAPE_GRAPH_VERSION
    • DHAPE_GRAPH_VERSION

    In case you find a missing function module, apply the latest DMIS 2018 support package.
