• What is the cause and solution for SAP error message MDC_LOAD094 - No insertion for "&1" (table &2), probably duplicate in line &3 ?

  The SAP error message MDC_LOAD094 indicates that there was an attempt to insert a record into a specified table, but the operation failed because the record being inserted is likely a duplicate of an existing record. This error typically occurs during data loading processes, such as when using the SAP Data Services or during the execution of a data load job.
  Cause:
  
  Duplicate Records: The most common cause of this error is that the record you are trying to insert already exists in the target table. This can happen if the data being loaded contains duplicates or if the data already present in the table was not properly accounted for.
  Primary Key Violation: If the target table has a primary key or unique constraint, attempting to insert a record with a key that already exists will trigger this error.
  Data Quality Issues: Poor data quality, such as missing or incorrect identifiers, can lead to unintended duplicates.
  
  Solution:
  
  Check for Duplicates: Before loading the data, check the source data for duplicates. You can use SQL queries or data profiling tools to identify duplicate records.
  Modify Load Logic: Adjust the data load logic to handle duplicates appropriately. This could involve:
  
  Updating Existing Records: Instead of inserting, update existing records if they already exist.
  Ignoring Duplicates: Skip records that are duplicates during the load process.
  Using Merge Logic: Implement a merge strategy that combines new and existing records based on certain criteria.
  
  
  Data Cleansing: Cleanse the data before loading it into the target table. This may involve removing duplicates, standardizing formats, and ensuring that all required fields are populated.
  Review Constraints: Review the constraints on the target table to ensure they are set up correctly and that they align with the data being loaded.
  
  Related Information:
  
  Transaction Logs: Check transaction logs or error logs for more details on the specific records that caused the error.
  SAP Notes: Look for relevant SAP Notes that may provide additional context or solutions for this error message.
  Data Load Tools: If you are using specific data load tools (like SAP Data Services), refer to their documentation for best practices on handling duplicates.
  Testing: Always test your data load processes in a development or test environment before executing them in production to catch issues like this early.
  
  By addressing the root cause of the duplicate records and implementing appropriate handling strategies, you can resolve the MDC_LOAD094 error and ensure successful data loading.
