• What is the cause and solution for SAP error message RSCRT121 - &1 &2 does not support real-time data acquisition (RDA) ?

  The SAP error message RSCRT121 indicates that a specific data source does not support Real-Time Data Acquisition (RDA). This error typically arises in the context of SAP BW (Business Warehouse) when trying to set up or use a data source that is not compatible with RDA.
  Cause:
  
  Data Source Compatibility: The data source you are trying to use is not designed to support real-time data acquisition. This can happen if the data source is a non-ODS (Operational Data Store) object or if it is not configured correctly for RDA.
  Configuration Issues: The data source may not be properly configured in the SAP BW system, or it may not have the necessary settings enabled for RDA.
  Version Limitations: Certain versions of SAP BW or specific data sources may not support RDA due to limitations in their design or functionality.
  
  Solution:
  
  Check Data Source Type: Verify that the data source you are using is compatible with RDA. You may need to switch to a different data source that supports RDA.
  Configuration Review: Review the configuration of the data source in the SAP BW system. Ensure that it is set up correctly and that all necessary settings for RDA are enabled.
  Use Delta Load: If RDA is not supported, consider using delta load methods instead of real-time data acquisition. This involves periodic data extraction rather than real-time updates.
  Consult Documentation: Refer to the SAP documentation for your specific version of BW to understand the capabilities and limitations of the data sources you are working with.
  SAP Notes: Check for any relevant SAP Notes that may address this issue. SAP frequently releases updates and patches that may resolve compatibility issues.
