• What is the cause and solution for SAP error message OQ_E102 - Transaction record already exists in system ?

  The SAP error message OQ_E102, which states "Transaction record already exists in system," typically occurs when you are trying to create a new transaction record (such as a sales order, purchase order, or any other transactional data) that duplicates an existing record in the system. This can happen for various reasons, including:
  Causes:
  
  Duplicate Entry: The most common cause is that the transaction you are trying to create already exists in the system with the same key fields (like document number, customer ID, etc.).
  Data Migration Issues: If data has been migrated from another system, there may be duplicate records that were not cleaned up.
  Concurrency Issues: If multiple users are trying to create the same record simultaneously, one of the transactions may be blocked due to the existing record.
  Custom Logic: Custom validations or enhancements in the SAP system may be enforcing unique constraints that are causing this error.
  
  Solutions:
  
  Check for Existing Records: Before creating a new transaction, check if a record with the same key fields already exists in the system. You can use transaction codes like SE16 or SE16N to query the relevant database tables.
  Modify the Input Data: If you find that a record already exists, you may need to modify your input data to create a new unique record.
  Data Cleanup: If the error is due to duplicate records from data migration, consider cleaning up the data to remove duplicates.
  Review Custom Code: If there are custom validations or enhancements, review the code to ensure that it is functioning as intended and not incorrectly flagging legitimate entries as duplicates.
  Consult Documentation: Check SAP documentation or notes related to the specific transaction you are working with for any known issues or additional guidance.
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or SAP support for further assistance.
