• What is the cause and solution for SAP error message RSODP_ABAP_CDS335 - Definition of view is too complex for automatic CDC ?

  The SAP error message RSODP_ABAP_CDS335 indicates that the definition of a Core Data Services (CDS) view is too complex for the automatic Change Data Capture (CDC) mechanism to handle. This typically occurs when the CDS view includes complex logic, such as multiple joins, subqueries, or other advanced SQL features that exceed the capabilities of the CDC framework.
  Causes:
  
  Complex Joins: The CDS view may involve multiple tables with complex join conditions.
  Subqueries: The use of subqueries can complicate the view definition.
  Aggregations: If the view includes aggregations or groupings, it may be too complex for CDC.
  Functions and Calculated Fields: The presence of complex calculations or custom functions can also lead to this error.
  Large Data Volume: If the view is expected to handle a large volume of data, it may exceed the limits set for CDC.
  
  Solutions:
  
  
  Simplify the CDS View: Review the view definition and try to simplify it by:
  
  Reducing the number of joins.
  Avoiding subqueries where possible.
  Breaking down complex calculations into simpler components.
  Creating multiple simpler views instead of one complex view.
  
  
  
  Use a Different Approach for CDC: If the complexity cannot be reduced, consider using a different method for capturing changes, such as:
  
  Implementing manual change tracking mechanisms.
  Using triggers or other database-level change tracking features.
  
  
  
  Check for Updates: Ensure that your SAP system is up to date, as newer versions may have improved capabilities for handling complex views in CDC.
  
  
  Consult Documentation: Refer to the official SAP documentation for guidelines on creating CDS views and best practices for CDC.
  
  
  Performance Tuning: If the view is necessary as is, consider performance tuning to ensure it runs efficiently, which may help with CDC processing.
