• What is the cause and solution for SAP error message CDS_UNIT_MESSAGE111 - Testing of a CDS hierarchy is not supported ?

  The error message CDS_UNIT_MESSAGE111 in SAP indicates that testing of a Core Data Services (CDS) hierarchy is not supported. This typically occurs when you are trying to execute or test a CDS view that involves hierarchical data structures, which are not supported in the testing environment.
  Cause:
  
  Hierarchical Structure: The CDS view you are trying to test is defined with a hierarchical structure (e.g., using the HIERARCHY keyword), which is not supported in the testing framework.
  Testing Environment Limitations: The testing environment for CDS views may not support certain features, especially those related to complex data structures like hierarchies.
  
  Solution:
  
  Avoid Testing Hierarchical CDS Views: If you need to test a CDS view that involves a hierarchy, consider executing it in a different environment (e.g., through a report or a transaction) rather than using the CDS testing tool.
  Simplify the CDS View: If possible, create a simplified version of the CDS view that does not include hierarchical structures for testing purposes.
  Use Alternative Tools: Instead of using the CDS testing tool, you can use other tools like ABAP reports or SQL queries to validate the data returned by the CDS view.
  Check Documentation: Review the SAP documentation for any updates or changes regarding the support of hierarchical CDS views in testing scenarios.
  
  Related Information:
