• What is the cause and solution for SAP error message /SCMUI/UIAPOMD108 - INSERT error: Key &1 already exists on database ?

  The SAP error message /SCMUI/UIAPOMD108 INSERT error: Key &1 already exists on database typically indicates that there is an attempt to insert a record into a database table where a unique key constraint is violated. This means that the key (in this case, represented by &1) you are trying to insert already exists in the database, and the system is preventing the insertion to maintain data integrity.
  Causes:
  
  
  Duplicate Key: The most common cause is that the key you are trying to insert already exists in the database. This could be due to:
  
  Manual data entry errors.
  Data being imported or uploaded that contains duplicates.
  A previous transaction that was not properly completed, leaving the key in the database.
  
  
  
  Concurrency Issues: If multiple users or processes are trying to insert the same key at the same time, one of them will succeed while the other will fail.
  
  
  Incorrect Logic in Custom Code: If there is custom code (like ABAP programs or enhancements) that handles data insertion, it may not be checking for existing keys before attempting to insert.
  
  
  Solutions:
  
  
  Check for Existing Records: Before attempting to insert a new record, check the database to see if a record with the same key already exists. You can do this by querying the relevant table.
  
  
  Modify the Insert Logic: If you are using custom code, ensure that it includes logic to handle existing records. For example, you might want to update the existing record instead of inserting a new one if it already exists.
  
  
  Data Cleanup: If the error is due to duplicate data being imported, you may need to clean up the data source to remove duplicates before attempting the import again.
  
  
  Error Handling: Implement error handling in your application to gracefully manage situations where a duplicate key is encountered, possibly by notifying the user or logging the error for further investigation.
  
  
  Database Constraints: Review the database constraints to ensure they are set up correctly. If the unique constraint is too strict for your business logic, you may need to reconsider the design.
  
  
  Related Information:
  
  Transaction Logs: Check transaction logs to identify when the duplicate key was created and by which process.
  SAP Notes: Look for relevant SAP Notes that might address this specific error or provide guidance on best practices for handling unique keys.
  Documentation: Review the documentation for the specific module or application you are working with to understand how it handles data insertion and key management.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or development team for further investigation.
