• What is the cause and solution for SAP error message RS_B4HANA_RC055 - Myself-DataSources must be remodelled via ODP-CDS in BW/4HANA ?

  The SAP error message RS_B4HANA_RC055 indicates that the DataSources in your BW/4HANA system need to be remodeled using ODP (Operational Data Provisioning) with CDS (Core Data Services). This error typically arises when you are trying to use legacy DataSources that are not compatible with the BW/4HANA architecture.
  Cause:
  
  Legacy DataSources: The error occurs because the DataSources you are trying to use are based on older technologies that are not supported in BW/4HANA.
  Transition to ODP/CDS: BW/4HANA relies on ODP and CDS for data extraction and modeling, which means that all DataSources must be redefined to align with these modern frameworks.
  Incompatibility: The existing DataSources may not be optimized for the new data model and architecture of BW/4HANA, leading to this error.
  
  Solution:
  To resolve the RS_B4HANA_RC055 error, you need to remodel your DataSources using ODP and CDS. Here are the steps to do this:
  
  
  Identify Legacy DataSources: Determine which DataSources are causing the error. This can usually be found in the error message details or logs.
  
  
  Use ODP for Data Extraction:
  
  Go to the SAP BW/4HANA system and access the Data Warehousing Workbench (transaction RSA1).
  Create new DataSources using the ODP framework. This can be done by selecting the appropriate source system and defining the DataSource based on the ODP capabilities.
  
  
  
  Define CDS Views:
  
  Create CDS views that represent the data you want to extract. This involves defining the necessary fields, joins, and filters in the CDS view.
  Ensure that the CDS views are optimized for performance and meet the requirements of your reporting needs.
  
  
  
  Activate and Test:
  
  After creating the new DataSources and CDS views, activate them in the system.
  Test the DataSources to ensure they are functioning correctly and that data can be extracted as expected.
  
  
  
  Update Data Models: If you have existing InfoObjects, InfoProviders, or queries that rely on the old DataSources, you will need to update them to use the new ODP/CDS-based DataSources.
  
  
  Documentation and Training: Ensure that your team is aware of the changes and provide documentation or training on how to work with ODP and CDS in BW/4HANA.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error.
  SAP Help Portal: Refer to the SAP Help Portal for detailed documentation on ODP and CDS in BW/4HANA.
