This error is often encountered in the context of the SAP Landscape Transformation (SLT) or during data migration projects.
  Cause:
  The primary cause of this error is the presence of duplicate entries in the source data that you are trying to migrate or transform. This can happen due to various reasons, such as:
  
  Data Quality Issues: The source data may have been poorly maintained, leading to duplicate records.
  Incorrect Data Extraction Logic: The logic used to extract data from the source system may not have properly filtered out duplicates.
  Multiple Sources: If data is being pulled from multiple sources, there may be overlaps that result in duplicates.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicates:
  
  Use SQL queries or data analysis tools to identify the duplicate records in the specified table. You can group by the relevant fields and count occurrences to find duplicates.
  
  
  
  Data Cleansing:
  
  Once duplicates are identified, you need to decide how to handle them. Options include:
  
  Removing duplicates if they are not needed.
  Merging records if they contain complementary information.
  Keeping one record and discarding others based on specific criteria (e.g., latest timestamp).
  
  
  
  
  
  Adjust Data Extraction Logic:
  
  If the duplicates are a result of the extraction process, review and modify the extraction logic to ensure that it filters out duplicates before they are loaded into the target system.
  
  
  
  Re-run the Data Selection:
  
  After addressing the duplicates, re-run the data selection process to see if the error persists.
  
  
  
  Consult Documentation:
  
  Check SAP documentation or notes related to the specific migration or transformation process you are using for any additional guidance or best practices.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to analyze the data in the relevant tables.
  SAP Notes: Look for SAP Notes related to the specific migration tool or process you are using, as they may provide additional insights or solutions.
  Data Migration Tools: Familiarize yourself with the tools and methodologies used for data migration in SAP, such as SAP Data Services, SAP S/4HANA Migration Cockpit, or SAP Landscape Transformation.
