• What is the cause and solution for SAP error message SZDM_CC_CHKS_RSDDIC021 - ZDO-Clone for pool change: too big or frequently updated ?

  The SAP error message SZDM_CC_CHKS_RSDDIC021 typically occurs in the context of SAP BW (Business Warehouse) when there are issues related to the data model, particularly when dealing with InfoProviders or data targets that are too large or frequently updated. This error is often associated with the ZDO (Zero Data Object) cloning process, which is part of the data loading and transformation processes in SAP BW.
  Cause:
  
  Data Volume: The error indicates that the data pool being processed is too large. This can happen if the InfoProvider or data target has a significant amount of data that needs to be processed in a single operation.
  Frequent Updates: If the data is being updated too frequently, it can lead to contention issues or performance bottlenecks, causing the system to throw this error.
  Configuration Issues: There may be configuration settings in the BW system that are not optimized for handling large datasets or frequent updates.
  Locking Issues: If multiple processes are trying to access or update the same data simultaneously, it can lead to locking issues that trigger this error.
  
  Solution:
  
  
  Optimize Data Volume:
  
  Consider breaking down large data loads into smaller batches. This can help manage the volume of data being processed at one time.
  Review the data model to ensure that it is optimized for performance. This may involve archiving old data or summarizing data where possible.
  
  
  
  Adjust Update Frequency:
  
  If possible, reduce the frequency of updates to the data target. This can help alleviate contention and locking issues.
  Schedule data loads during off-peak hours to minimize the impact on system performance.
  
  
  
  Configuration Review:
  
  Review the configuration settings for the InfoProvider or data target. Ensure that they are set up to handle the expected data volume and update frequency.
