• What is the cause and solution for SAP error message RSAU338 - Update terminated because InfoPackage contains duplicate data records ?

  The SAP error message RSAU338 indicates that an InfoPackage has encountered duplicate data records during the data loading process, which has caused the update to terminate. This error typically occurs in the context of SAP BW (Business Warehouse) when loading data from a source system into the data warehouse.
  Cause:
  The primary cause of this error is the presence of duplicate records in the data being loaded. This can happen for several reasons, including:
  
  Source Data Issues: The source system may have duplicate entries that are being extracted.
  Data Transformation: During the ETL (Extract, Transform, Load) process, transformations may inadvertently create duplicates.
  Data Model Design: The design of the data model may not adequately handle unique constraints, leading to duplicates being allowed.
  
  Solution:
  To resolve the RSAU338 error, you can take the following steps:
  
  
  Identify Duplicates:
  
  Check the source data for duplicates. You can run queries or reports in the source system to identify records that are duplicated.
  Use transaction codes like SE16 or SE11 to analyze the data in the relevant tables.
  
  
  
  Modify the InfoPackage:
  
  If the duplicates are acceptable in the context of your data model, you can adjust the InfoPackage settings to allow duplicates. However, this is generally not recommended unless you have a specific reason to do so.
  
  
  
  Data Cleansing:
  
  Clean the source data to remove duplicates before loading it into SAP BW. This may involve modifying the extraction logic or applying filters to the data.
  
  
  
  Adjust Data Transformation Logic:
  
  Review any transformation rules applied during the data load process. Ensure that they are not inadvertently creating duplicates.
  
  
  
  Check Data Model Constraints:
  
  Ensure that the data model in SAP BW is designed to handle unique records appropriately. This may involve setting up unique keys or constraints in the data model.
  
  
  
  Re-run the Load:
  
  After addressing the duplicates, re-run the InfoPackage to load the data again.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  Data Quality Tools: Consider using data quality tools or features within SAP BW to monitor and manage data quality, which can help prevent such issues in the future.
  Documentation: Review SAP documentation related to InfoPackages and data loading processes for best practices and troubleshooting tips.
  
  By following these steps, you should be able to resolve the RSAU338 error and successfully load your data into SAP BW.
