• What is the cause and solution for SAP error message RSDDG010 - Rows with the same or an existing key were not inserted ?

  The SAP error message RSDDG010, which states "Rows with the same or an existing key were not inserted," typically occurs in the context of data loading into SAP BW (Business Warehouse) or during the data extraction process. This error indicates that there is a conflict with the primary key of the data being loaded, meaning that the system is trying to insert rows that have duplicate keys or keys that already exist in the target data store.
  Causes:
  
  Duplicate Data: The data being loaded contains duplicate records that have the same key values as existing records in the target InfoObject or InfoProvider.
  Data Source Issues: The source data may have inconsistencies or duplicates that were not addressed before the load.
  Incorrect Data Transformation: During the ETL (Extract, Transform, Load) process, transformations may not have been applied correctly, leading to duplicate keys.
  Data Model Design: The design of the data model may not adequately handle the uniqueness of keys, especially if the key structure is not well defined.
  
  Solutions:
  
  Check Source Data: Review the source data for duplicates. You can use tools like Excel or SQL queries to identify and remove duplicate records before loading.
  Adjust Data Transformation Logic: If you are using transformations in your data flow, ensure that they are correctly configured to handle duplicates. You may need to aggregate or filter data to ensure uniqueness.
  Modify Data Load Settings: In some cases, you can adjust the data load settings in the InfoPackage or DTP (Data Transfer Process) to handle duplicates differently, such as by updating existing records instead of inserting new ones.
  Use Data Quality Tools: Implement data quality checks to ensure that the data being loaded meets the required standards and does not contain duplicates.
  Review Key Definitions: Ensure that the key definitions in your InfoObjects and InfoProviders are correctly set up to reflect the uniqueness of the data being loaded.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to monitor and manage data loads.
  Error Logs: Check the error logs in the Data Transfer Process (DTP) or InfoPackage for more detailed information about the records that caused the error.
  SAP Notes: Look for relevant SAP Notes that may address specific issues related to this error message or provide patches and updates.
  Documentation: Refer to SAP BW documentation for best practices on data loading and handling duplicates.
  
  By addressing the root cause of the duplicate keys and ensuring that your data is clean and well-structured, you can resolve the RSDDG010 error and successfully load your data into SAP BW.
