• What is the cause and solution for SAP error message SDDL_PARSER_MSG484 - Data source with parameters cannot be used in projection view ?

  The SAP error message SDDL_PARSER_MSG484 indicates that there is an issue with using a data source that has parameters in a projection view. This typically occurs in the context of SAP HANA or SAP BW when you are trying to create or use a projection view that references a data source (like a table or a calculation view) that has parameters defined.
  Cause:
  The primary cause of this error is that projection views in SAP HANA do not support data sources that have parameters. When you attempt to use such a data source in a projection view, the system raises this error because it cannot resolve the parameters at the time of view execution.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Remove Parameters: If possible, modify the data source to remove the parameters. This may involve creating a new version of the data source that does not require parameters.
  
  
  Use a Different View Type: Instead of using a projection view, consider using a different type of view that supports parameters, such as a calculation view. Calculation views can handle parameters and allow for more complex logic.
  
  
  Refactor the Logic: If the logic of your data source is dependent on parameters, you may need to refactor your design to accommodate the limitations of projection views. This could involve creating intermediate views or tables that do not require parameters.
  
  
  Check Documentation: Review the SAP documentation for the specific version of SAP HANA or SAP BW you are using. There may be additional guidelines or best practices for working with views and data sources.
  
  
  Related Information:
