• What is the cause and solution for SAP error message RSQU064 - Synchronization: Delta initialization for system &2 is inconsistent ?

  The SAP error message RSQU064 indicates that there is an inconsistency during the delta initialization process for a specific system. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when dealing with data extraction and loading processes.
  Cause:
  The error can be caused by several factors, including:
  
  Inconsistent Data: The data in the source system may not match the data in the target system, leading to inconsistencies during the delta initialization process.
  Delta Queue Issues: The delta queue in the source system may have been corrupted or not properly processed, causing issues during the initialization.
  Configuration Errors: Incorrect settings in the data source or in the BW system can lead to synchronization issues.
  Data Source Changes: If there have been changes to the data source (like changes in the structure or fields), it can lead to inconsistencies.
  Network Issues: Temporary network issues during data transfer can also cause this error.
  
  Solution:
  To resolve the RSQU064 error, you can follow these steps:
  
  
  Check Delta Queue: 
  
  Go to the source system and check the delta queue for the data source. Ensure that it is not empty and that there are no errors in the delta queue.
  You can use transaction code RSA7 to monitor the delta queue.
  
  
  
  Reinitialize Delta:
  
  If the delta queue is inconsistent, you may need to reinitialize the delta process. This involves:
  
  Deleting the existing delta initialization.
  Performing a full data load from the source system to the BW system.
  After the full load, set up the delta initialization again.
  
  
  
  
  
  Check Data Source Configuration:
  
  Verify the configuration of the data source in the BW system. Ensure that all settings are correct and that there are no discrepancies between the source and target systems.
  
  
  
  Monitor Data Transfer:
  
  Use transaction SM37 to check for any background jobs related to data transfer that may have failed or encountered issues.
  
  
  
  Check for Changes:
  
  If there have been recent changes to the data source (like changes in fields or structure), ensure that these changes are reflected in the BW system.
  
  
  
  Consult Logs:
  
  Check the logs for more detailed error messages. You can use transaction SLG1 to view application logs related to the data transfer.
  
  
  
  SAP Notes:
  
  Search for relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide solutions or workarounds for known issues.
