• What is the cause and solution for SAP error message SDDL_PARSER_MSG384 - Projection views are not supported ?

  The SAP error message SDDL_PARSER_MSG384 indicates that projection views are not supported in the context where you are trying to use them. This error typically arises when working with SAP HANA or when dealing with certain types of data modeling in SAP systems, particularly in the context of CDS (Core Data Services) views or when using the SAP Data Warehouse.
  Cause:
  The error occurs because projection views, which are a specific type of view that only selects certain columns from a base table or view, are not supported in the operation you are attempting. This can happen in scenarios such as:
  
  Incompatible View Types: You may be trying to use a projection view in a context that requires a different type of view (e.g., a calculation view or a different data model).
  Data Model Restrictions: Certain data modeling scenarios or tools may not support projection views due to their limitations or design.
  Incorrect Configuration: There may be a misconfiguration in your data model or the way views are defined.
  
  Solution:
  To resolve the error, consider the following steps:
  
  
  Check View Type: Ensure that you are using the correct type of view for your requirements. If you need to perform operations that require a different view type, consider converting your projection view to a calculation view or another supported type.
  
  
  Review Data Model: Examine your data model to ensure that it aligns with the requirements of the operation you are trying to perform. If necessary, redesign the model to avoid using projection views in unsupported contexts.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the limitations and supported features of views in your environment.
  
  
  Error Context: Look at the context in which the error occurs. If it is during a specific operation (e.g., data extraction, reporting), check if there are alternative methods or configurations that can be used.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with a technical expert who has experience with SAP HANA and data modeling.
  
  
  Related Information:
  
  SAP HANA Documentation: Review the official SAP HANA documentation for details on view types and their capabilities.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  Training and Tutorials: Consider taking training courses or tutorials on SAP HANA and data modeling to better understand the concepts and best practices.
  
  By following these steps, you should be able to identify the cause of the error and implement a suitable solution.
