• What is the cause and solution for SAP error message RSDU_REPART120 - Maximum number of parallel conversions reached ?

  The SAP error message RSDU_REPART120 indicates that the maximum number of parallel conversions has been reached in the context of data extraction or data loading processes, particularly in SAP BW (Business Warehouse) or SAP HANA environments. This error typically occurs when there are too many concurrent data processing tasks running at the same time, which exceeds the system's configured limits.
  Cause:
  
  High Load: The system is processing too many data requests simultaneously, which can happen during peak times or when multiple data loads are scheduled to run at the same time.
  Configuration Limits: The system has a predefined limit on the number of parallel processes that can be executed, and this limit has been reached.
  Resource Constraints: Insufficient system resources (CPU, memory) can also lead to this error, as the system may not be able to handle additional parallel processes.
  
  Solution:
  
  
  Reduce Parallel Processes:
  
  Review and adjust the scheduling of data loads to avoid overlapping processes. Stagger the execution times of data loads to ensure that they do not run concurrently.
  If possible, limit the number of parallel data loads in the process chain settings.
  
  
  
  Increase Configuration Limits:
  
  If your system resources allow, consider increasing the maximum number of parallel conversions allowed. This can typically be done in the SAP BW settings or through transaction codes like RSCUSTV10 (for BW) or similar configuration transactions.
  Consult with your SAP Basis team to evaluate the current settings and determine if they can be adjusted.
  
  
  
  Monitor System Performance:
  
  Use transaction codes like ST03N or ST06 to monitor system performance and identify any bottlenecks.
  Check for any long-running processes that may be consuming resources and causing delays.
  
  
  
  Optimize Data Loads:
  
  Review the data load processes for optimization opportunities. This may include optimizing the data extraction logic, reducing the volume of data being processed, or improving the performance of the underlying database.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes or updates related to this error message. There may be specific patches or recommendations provided by SAP.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSCUSTV10 (for customizing BW settings), RSPC (Process Chains), and ST22 (Dump Analysis) for troubleshooting.
  SAP Documentation: Refer to SAP Help documentation for detailed information on data loading processes and performance tuning in SAP BW or HANA.
  SAP Community: Engage with the SAP Community forums for insights and solutions shared by other users who may have encountered similar issues.
  
  By following these steps, you should be able to address the RSDU_REPART120 error and improve the performance of your data loading processes in SAP.
