  The SAP error message RS_B4HANA_RC051 indicates that a DataSource in SAP BW/4HANA needs to be manually remodeled using SAP HANA Smart Data Integration (SDI). This typically occurs when the DataSource is not compatible with the new data modeling capabilities or structures introduced in BW/4HANA.
  Cause:
  
  DataSource Compatibility: The DataSource may have been created in an older version of SAP BW and is not compatible with the BW/4HANA architecture.
  Modeling Changes: BW/4HANA introduces new modeling concepts and optimizations that require certain DataSources to be redefined or remodeled.
  Data Flow Changes: Changes in how data is processed and stored in HANA may necessitate a manual intervention to ensure that the DataSource aligns with the new data flow and storage mechanisms.
  
  Solution:
  To resolve the RS_B4HANA_RC051 error, follow these steps:

  Ensure that the DataSource is set up to leverage the capabilities of HANA, such as using calculation views or other HANA-native objects.
  
  
  
  Test the DataSource: After remodeling, test the DataSource to ensure that it functions correctly and that data is being loaded as expected.
  
  
  Update BW/4HANA: Once the DataSource is remodeled, update any relevant BW/4HANA objects (like InfoProviders, Queries, etc.) to ensure they reference the new DataSource correctly.
