Symptom
On SAP Datasphere, Replication Flows of load type: 'INITIAL and DELTA' fail for CDS views from S/4HANA On-premise source systems.
The offending CDS views have been manually annotated for delta extraction per the requirements described in SAP Note 2890171 - SAP Data Intelligence - ABAP Integration.
The views are available for consumption on SAP Datasphere for Replication Flows. However the corresponding Replication Flow run fails with errors:
Cannot replicate data from CDS view I_PROFITCENTERHIERARCHYNODE; WHERE condition is too complex
Definition of view is too complex for automatic CDC
The delta extraction of the same views on the source system via t-code SA38 -> RODPS_REPL_TEST fails with the message:
source <VIEW> does not support deltas.
Environment
SAP Datasphere
Cause
CDS view definition is too complex to support delta extraction.
Resolution
Fix the definition of the offending views as described in SAP KBA 3195275 - Customizing ABAP CDC: does not support deltas.
