• What is the cause and solution for SAP error message RSM1644 - Real-time data acquisition does not support 3.x DataSources ?

  The SAP error message RSM1644 indicates that there is an issue with using Real-Time Data Acquisition (RDA) with a 3.x DataSource. This error typically arises when you attempt to use a 3.x DataSource in a context that only supports 2.x DataSources, particularly in the context of SAP BW (Business Warehouse) or SAP BW/4HANA.
  Cause:
  
  DataSource Version: The primary cause of this error is that the DataSource you are trying to use is a 3.x version, which is not compatible with Real-Time Data Acquisition. RDA is designed to work with 2.x DataSources.
  Configuration Issues: There may be a misconfiguration in the settings of the DataSource or the data flow that is leading to this error.
  Incompatibility with RDA: The specific features or functionalities of the 3.x DataSource may not be supported in the RDA framework.
  
  Solution:
  
  Use 2.x DataSources: If you need to use Real-Time Data Acquisition, you should switch to a 2.x DataSource. You can create a new 2.x DataSource that replicates the data structure and logic of your existing 3.x DataSource.
  Modify Data Flow: If you are using a 3.x DataSource for a specific data flow, consider modifying the data flow to accommodate a 2.x DataSource instead.
  Check Configuration: Review the configuration settings of your DataSource and ensure that it is set up correctly for the intended use case. Make sure that you are not inadvertently trying to use RDA with a 3.x DataSource.
  Consult Documentation: Refer to SAP documentation for guidance on DataSource compatibility and best practices for Real-Time Data Acquisition.
  
  Related Information:
  
  DataSource Types: Understand the differences between 2.x and 3.x DataSources. 2.x DataSources are generally simpler and designed for use with BW, while 3.x DataSources offer more complex data extraction capabilities.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error message.
  SAP Community: Engage with the SAP Community forums for discussions and solutions shared by other users who may have encountered similar issues.
  Upgrade Considerations: If you are working with an older version of SAP BW, consider upgrading to a newer version that may provide better support for real-time data acquisition and compatibility with various DataSource types.
  
  By addressing the compatibility issue and ensuring that you are using the correct DataSource type, you should be able to resolve the RSM1644 error.
