• What is the cause and solution for SAP error message RSAN_RT804 - Intermediate result for node &1 has been deleted ?

  The SAP error message RSAN_RT804 indicates that an intermediate result for a specific node in a data processing operation has been deleted. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when executing queries or data processing tasks that involve multiple steps or nodes.
  Cause:
  
  Data Processing Interruption: The intermediate result may have been deleted due to an interruption in the data processing, such as a timeout or a manual cancellation of the process.
  Memory Management: SAP BW uses memory management techniques to handle large datasets. If the system runs out of memory or if the intermediate results are not needed anymore, they may be deleted.
  Query Execution: If a query is executed that requires intermediate results from a previous step, and those results have been deleted, this error can occur.
  Configuration Issues: There may be configuration issues in the data flow or in the settings of the InfoProvider or query that lead to the deletion of intermediate results.
  
  Solution:
  
  Re-run the Query: Often, simply re-running the query or data processing task can resolve the issue, as it will regenerate the necessary intermediate results.
  Check for Interruptions: Investigate if there were any interruptions during the data processing. Look into system logs or transaction logs to identify any issues that may have caused the deletion.
  Increase Memory Allocation: If memory issues are suspected, consider increasing the memory allocation for the SAP BW system or optimizing the data processing to reduce memory consumption.
  Review Data Flow Configuration: Check the configuration of the data flow and ensure that all nodes are correctly set up and that there are no missing links or dependencies.
  Update SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide patches that could resolve underlying issues.
  Consult SAP Support: If the issue persists, consider reaching out to SAP Support for further assistance, especially if this is affecting production systems.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like RSA1 (Data Warehousing Workbench) to analyze the data flow and check the status of InfoProviders.
  Monitoring Tools: Utilize monitoring tools within SAP BW to track the execution of queries and data loads, which can help identify where the issue is occurring.
  Performance Tuning: Regularly perform performance tuning on your BW system to ensure optimal operation and to prevent issues related to memory and processing.
  
  By following these steps, you should be able to diagnose and resolve the RSAN_RT804 error effectively.
