• What is the cause and solution for SAP error message LTR_PRESEL013 - Duplicate records have been deleted during insertion for package &1 ?

  The SAP error message LTR_PRESEL013 indicates that during the insertion of data into a package, duplicate records were detected and subsequently deleted. This typically occurs in the context of data loading processes, such as when using the SAP Landscape Transformation (SLT) Replication Server or during data migration activities.
  Cause:
  
  Duplicate Data: The primary cause of this error is the presence of duplicate records in the source data that are being loaded into the target system. This can happen if the source system has not been properly cleansed or if the data extraction process does not filter out duplicates.
  Primary Key Violations: If the target table has a primary key or unique constraints, any attempt to insert duplicate records will lead to this error as the database enforces uniqueness.
  Data Transformation Issues: If there are issues in the data transformation logic that lead to the generation of duplicate records, this can also trigger the error.
  
  Solution:
  
  Data Cleansing: Review the source data for duplicates and cleanse it before loading. This may involve using SQL queries or data processing tools to identify and remove duplicates.
  Check Data Extraction Logic: Ensure that the data extraction process is correctly configured to avoid pulling in duplicate records. This may involve adjusting filters or conditions in the extraction logic.
  Review Transformation Rules: If you are using transformation rules, ensure that they are correctly set up to prevent the creation of duplicates during the data load process.
  Adjust Load Settings: If applicable, adjust the settings in the data load process to handle duplicates according to your business requirements (e.g., ignore duplicates, update existing records, etc.).
  Monitoring and Logging: Implement monitoring and logging to capture details about the records being processed. This can help identify patterns or specific records that are causing the issue.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to this error.
