• What is the cause and solution for SAP error message RSB4HANA119 - Subscriber &1 (&2 data sources) must be supplied via CDS, not via SAPI ?

  The SAP error message RSB4HANA119 indicates that a specific data source (in this case, a subscriber) must be supplied using Core Data Services (CDS) rather than the SAP Application Programming Interface (SAPI). This error typically arises in the context of SAP BW/4HANA or SAP BW on HANA when trying to use a data source that is expected to be accessed via CDS views instead of the older SAPI method.
  Cause:
  
  Data Source Type: The data source you are trying to use is designed to be accessed through CDS views, which are optimized for HANA and provide better performance and capabilities compared to SAPI.
  Configuration Issue: The data source may not be properly configured to use CDS, or there may be an attempt to access it using an outdated method (SAPI).
  Version Compatibility: The version of SAP BW/4HANA or the specific data source may not support SAPI, as newer versions are moving towards CDS for data access.
  
  Solution:
  
  Use CDS Views: Ensure that you are using the correct CDS views for the data source. You may need to create or modify existing CDS views to meet your requirements.
  Check Data Source Configuration: Review the configuration of the data source in the SAP BW system. Make sure it is set up to be accessed via CDS.
  Update Queries: If you have queries or reports that are using the data source, update them to reference the appropriate CDS views instead of the SAPI data source.
  Documentation and Guides: Refer to SAP documentation for guidance on how to work with CDS views and how to migrate from SAPI to CDS if necessary.
  Consult SAP Notes: Check for any relevant SAP Notes that may provide additional information or fixes related to this error message.
