SAP Datasphere

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

1. Make sure to have following Function Modules in your ABAP Source system:
   
   • 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.
   Function LTAPE_GRAPH_VERSION is part of DMIS addon.

   For ABAP Connection in Datasphere the DMIS addon is a must.
   As mentioned in central SAP Note 2890171 - SAP Data Intelligence / SAP Datasphere - ABAP Integration
   "In general, corrections for the ABAP Integration are delivered via SAP Notes. To check whether all available SAP Notes are installed, you can use the Note Analyzer tool - for more details, see SAP Note 3016862. 
   Once DMIS Addon is installed, the connectivity problem will get resolved.

     
2. Make sure to add the required resources in the Cloud Connector as per Datasphere Help page Configure Cloud Connector #3 Section d.
