• What is the cause and solution for SAP error message RSDSO_UPDATE064 - Duplicates are allowed and will be overwritten ?

  The SAP error message RSDSO_UPDATE064 indicates that there is an issue with data duplication in the context of data updates in SAP BW (Business Warehouse) or SAP HANA. This message typically arises when you are trying to load data into a DataStore Object (DSO) or InfoProvider, and the system detects that the incoming data contains duplicates that will overwrite existing records.
  Cause:
  
  Duplicate Records: The incoming data contains records that have the same key as existing records in the DSO. In SAP BW, DSOs are designed to store data at a detailed level, and each record is identified by a unique key.
  Data Load Process: The data load process is set to allow duplicates, which means that the system will overwrite existing records with the new incoming data.
  Data Source Configuration: The configuration of the data source or transformation might be set to allow duplicates, leading to this message.
  
  Solution:
  
  Check Data Source: Review the data source and ensure that it is configured correctly. If duplicates are not intended, you may need to adjust the data extraction or transformation logic to eliminate duplicates before loading.
  Adjust DSO Settings: If you want to prevent overwriting, you can change the settings of the DSO to disallow duplicates. This can be done in the DSO settings in the SAP BW system.
  Data Cleansing: Implement data cleansing processes to ensure that the data being loaded does not contain duplicates. This can involve using queries or transformations to filter out duplicate records before they reach the DSO.
  Review Transformation Logic: Check the transformation logic in the data load process. Ensure that it is correctly handling duplicates according to your business requirements.
  Monitoring and Logging: Enable detailed logging for the data load process to identify where duplicates are being introduced. This can help in troubleshooting and resolving the issue.
  
  Related Information:
  
  DataStore Object (DSO): A DSO is a type of InfoProvider in SAP BW that stores detailed transactional data. It allows for data updates and can be configured to handle duplicates in various ways.
  Data Load Process: Understanding the data load process in SAP BW, including the extraction, transformation, and loading (ETL) phases, is crucial for managing data integrity.
  SAP Notes and Documentation: Check SAP Notes and official documentation for any specific guidance or updates related to the RSDSO_UPDATE064 error message. SAP frequently updates its knowledge base with solutions to common issues.
  
  By addressing the root cause of the duplicates and adjusting the configuration or data handling processes, you can resolve the RSDSO_UPDATE064 error and ensure smooth data loading into your SAP BW environment.
