  The SAP error message J2587 with the description "An entry with the same key (&1, &2) already exists" typically indicates that there is an attempt to create or update a record in the system that conflicts with an existing record. The placeholders &1 and &2 usually represent specific key fields that identify the record in question.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that the system is trying to insert or update a record that already exists in the database with the same key values.
  Data Migration Issues: If data is being migrated from another system or uploaded in bulk, it may lead to duplicates if the data is not properly cleaned or validated before the upload.
  Concurrency Issues: If multiple users or processes are trying to create or update the same record simultaneously, it can lead to this error.
  Incorrect Logic in Custom Code: If there is custom ABAP code or enhancements that handle data insertion or updates, there may be logic errors leading to attempts to create duplicate entries.
  
  Solution:
  
  Check Existing Records: Before attempting to create or update a record, check the database to see if an entry with the same key already exists. You can use transaction codes like SE16 or SE11 to view the relevant database table.
  Data Validation: Implement data validation checks in your application or during data migration to ensure that duplicates are not created.
  Modify Logic: If the error is due to custom code, review and modify the logic to handle existing records appropriately (e.g., update instead of insert).
  Error Handling: Implement error handling in your application to gracefully manage situations where a duplicate entry is detected.
  Consult Documentation: Review SAP documentation or notes related to the specific transaction or module you are working with for any additional guidance or known issues.
