• What is the cause and solution for SAP error message CFM_TR_BIW020 - **** Messages for OLTP-OLAP reconciliation ***************** ?

  The SAP error message CFM_TR_BIW020 is related to the reconciliation between OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing) systems, specifically in the context of SAP BW (Business Warehouse) and SAP ERP systems. This message typically indicates that there is a discrepancy between the data in the OLTP system and the data that has been extracted and loaded into the OLAP system.
  Cause:
  The causes of this error can vary, but common reasons include:
  
  
  Data Inconsistencies: There may be inconsistencies in the data between the source (OLTP) and the target (OLAP) systems. This can happen due to:
  
  Missing or incomplete data in the OLTP system.
  Data that has been changed or deleted in the OLTP system after it was extracted for the OLAP system.
  
  
  
  Extraction Issues: Problems during the data extraction process can lead to incomplete or incorrect data being loaded into the OLAP system.
  
  
  Transformation Errors: Errors during the transformation of data from the OLTP format to the OLAP format can also cause discrepancies.
  
  
  Load Failures: If the data load process into the OLAP system fails or is interrupted, it can lead to mismatches.
  
  
  Timing Issues: If the OLTP data is updated after the extraction process has started, it can lead to inconsistencies.
  
  
  Solution:
  To resolve the CFM_TR_BIW020 error, you can follow these steps:
  
  
  Check Data Consistency: Verify the data in both the OLTP and OLAP systems. Look for any missing or inconsistent records.
  
  
  Re-run Data Extraction: If you suspect that the extraction process was not completed successfully, re-run the data extraction job to ensure that all relevant data is captured.
  
  
  Review Transformation Rules: Check the transformation rules in your ETL (Extract, Transform, Load) process to ensure that they are correctly defined and applied.
  
  
  Monitor Load Processes: Ensure that the data load processes are running without errors. Check the logs for any issues during the load.
  
  
  Use Reconciliation Reports: Utilize SAP BW reconciliation reports to identify discrepancies between the OLTP and OLAP data. These reports can help pinpoint where the inconsistencies lie.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional guidance or fixes related to this error.
  
  
  Engage Technical Support: If the issue persists, consider reaching out to SAP support for further assistance, especially if it involves complex data issues.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench) and RSMO (Monitor Data Load) to monitor and manage data loads.
  SAP BW Documentation: Review SAP BW documentation for best practices on data extraction and loading processes.
  Data Quality Tools: Consider implementing data quality tools to help maintain consistency between OLTP and OLAP systems.
  
  By following these steps, you should be able to identify and resolve the underlying issues causing the CFM_TR_BIW020 error message.
