• What is the cause and solution for SAP error message RSDRO559 - Difference in rows: &1 ?

  The SAP error message RSDRO559, which states "Difference in rows: &1," typically occurs in the context of SAP BW (Business Warehouse) when there is a discrepancy in the number of rows between the data source and the target data object (like an InfoProvider or a DataStore Object). This error can arise during data loading or data extraction processes.
  Cause:
  The error can be caused by several factors, including:
  
  Data Source Issues: The data source may have changed, leading to a mismatch in the expected number of rows.
  Transformation Errors: If there are transformations applied to the data during the loading process, they may inadvertently filter out or modify rows.
  Data Quality Issues: Inconsistent or corrupt data in the source system can lead to discrepancies.
  Delta Load Issues: If you are performing a delta load, there may be issues with the delta mechanism that cause rows to be missed or duplicated.
  Data Model Changes: Changes in the data model (like changes in InfoObjects or InfoProviders) can lead to mismatches in row counts.
  
  Solution:
  To resolve the RSDRO559 error, you can take the following steps:
  
  
  Check Data Source: Verify that the data source is correct and that it contains the expected number of rows. You can do this by running a query or report directly against the source system.
  
  
  Review Transformations: Examine any transformations applied during the data load process. Ensure that they are correctly configured and not filtering out necessary rows.
  
  
  Data Quality Checks: Perform data quality checks on the source data to identify any inconsistencies or corrupt records that may be causing the issue.
  
  
  Re-run the Load: If the issue was temporary, re-running the data load might resolve the discrepancy.
  
  
  Check Delta Mechanism: If you are using delta loads, ensure that the delta mechanism is functioning correctly. You may need to reset the delta pointer or perform a full load if necessary.
  
  
  Monitor Load Process: Use the SAP BW monitoring tools to track the load process and identify where the discrepancy occurs.
  
  
  Consult Logs: Check the application logs (transaction SLG1) for any additional error messages or warnings that could provide more context about the issue.
  
  
  Data Model Review: If there have been recent changes to the data model, review those changes to ensure they are not causing the discrepancy.
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to monitor and manage data loads.
  SAP Notes: Check SAP Notes for any known issues related to RSDRO559 or similar errors. SAP frequently updates its knowledge base with solutions and workarounds.
  Documentation: Refer to SAP BW documentation for best practices on data loading and transformation processes.
