• What is the cause and solution for SAP error message RSOS140 - Scheduling delta indexing every 5 minutes is recommended ?

  The SAP error message RSOS140 indicates that the delta indexing for a DataSource is being scheduled every 5 minutes, which is not optimal for performance. This message is a warning rather than a critical error, but it suggests that the current configuration may lead to performance issues or inefficiencies in the system.
  Cause:
  The cause of this message is typically related to the configuration of the delta indexing process in SAP BW (Business Warehouse). Delta indexing is used to update the data in the InfoCube or DataStore Object (DSO) with new or changed records from the source system. Scheduling delta indexing too frequently (like every 5 minutes) can lead to:
  
  Performance Issues: Frequent delta indexing can consume significant system resources, leading to performance degradation.
  Increased Load on Source System: It can put unnecessary load on the source system, especially if the data volume is high.
  Data Latency: While it may seem beneficial to have more frequent updates, it can lead to data latency issues if the system cannot keep up with the indexing frequency.
  
  Solution:
  To resolve this issue, consider the following solutions:
  
  
  Adjust the Delta Indexing Frequency:
  
  Review the business requirements for data freshness. If real-time data is not critical, consider increasing the interval for delta indexing (e.g., every 15 minutes, hourly, or daily).
  You can change the scheduling of the delta indexing job in the SAP BW system by accessing the process chain or the job scheduling settings.
  
  
  
  Monitor and Optimize Performance:
  
  Monitor the performance of the delta indexing process and the overall system. Use transaction codes like ST03N (Workload Analysis) and ST22 (Dump Analysis) to identify any bottlenecks.
  Optimize the data flow and ensure that the source system can handle the load.
  
  
  
  Review Data Volume:
  
  Analyze the volume of data being transferred during each delta indexing. If the volume is low, a less frequent schedule may be sufficient.
  If the volume is high, consider partitioning the data or using other optimization techniques.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to delta indexing and performance tuning for specific recommendations based on your version of SAP BW.
  
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to manage and monitor data flows and process chains.
  SAP Notes: Check for relevant SAP Notes that may provide additional insights or updates regarding delta indexing and performance tuning.
  Performance Monitoring Tools: Utilize SAP BW performance monitoring tools to analyze the impact of delta indexing on system performance.
  
  By addressing the frequency of delta indexing and optimizing the overall data flow, you can mitigate the issues associated with the RSOS140 message and improve the performance of your SAP BW system.
