• What is the cause and solution for SAP error message RSODP_ABAP_CDS336 - Complex WHERE condition may lead to wrong CDC delta ?

  The SAP error message RSODP_ABAP_CDS336 indicates that there is a potential issue with the complex WHERE condition in a Core Data Services (CDS) view that could lead to incorrect Change Data Capture (CDC) delta results. This error typically arises when the WHERE clause in the CDS view is too complex or not properly defined, which can affect the delta extraction process.
  Cause:
  
  Complex WHERE Conditions: The error is often triggered by complex logical conditions in the WHERE clause that may not be properly handled by the CDC mechanism.
  Non-Deterministic Results: If the WHERE condition includes non-deterministic functions or operations, it can lead to inconsistent results during delta extraction.
  Inconsistent Data: If the underlying data changes frequently or is not consistent, it can also lead to issues with delta extraction.
  
  Solution:
  
  Simplify the WHERE Clause: Review the WHERE condition in the CDS view and try to simplify it. Avoid using complex logical expressions that could lead to ambiguity.
  Use Deterministic Functions: Ensure that the functions used in the WHERE clause are deterministic, meaning they always produce the same output for the same input.
  Test the CDS View: Execute the CDS view in the SAP system to check if it returns the expected results without errors. This can help identify any issues with the data or logic.
  Check for Data Consistency: Ensure that the underlying data is consistent and does not change unexpectedly during the delta extraction process.
  Consult Documentation: Refer to SAP documentation or notes related to CDC and CDS views for any specific guidelines or best practices.
