  The SAP error message RSRTS_CDS027 typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with Composite Data Sources (CDS) views. The error indicates that there is an unsupported path entry type in the CDS view being accessed or used in a query.
  Cause:
  The error can be caused by several factors, including:
  
  Unsupported Data Types: The CDS view may contain data types or structures that are not supported in the context of the query or reporting tool being used.
  Incorrect Path Definition: The path defined in the CDS view may reference fields or structures that are not valid or do not exist.
  Changes in Data Model: If there have been recent changes to the underlying data model or the CDS view itself, it may lead to inconsistencies that trigger this error.
  Version Compatibility: The version of the SAP BW or HANA system may not support certain features or data types used in the CDS view.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the CDS View Definition:

  This can help isolate whether the issue is with the view itself or with how it is being used in a report.
  
  
  
  Check for Recent Changes:
  
  If there have been recent changes to the data model or the CDS view, consider reverting those changes or adjusting the view to accommodate them.
