  The SAP error message RW014, which states "FI/CO interface: Line item entered several times," typically occurs in the context of financial accounting (FI) and controlling (CO) when there are duplicate line items being processed in the interface. This can happen during the posting of documents or during the transfer of data between modules.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the same line item has been entered multiple times in the document. This can happen due to user error or system issues.

  Solution:
  
  Check for Duplicates: Review the document being posted to ensure that there are no duplicate line items. This can be done by checking the document in the relevant transaction (e.g., FB01 for document posting).
  Adjust Configuration: If the issue is related to configuration, review the settings in the FI/CO interface to ensure that they are set up correctly to prevent duplicate entries.
  Data Validation: Implement validation checks in the data transfer process to ensure that duplicates are not included before they reach the FI/CO interface.
  Batch Input Review: If using batch input sessions, check the session logs to identify if the same data is being processed multiple times and adjust the input accordingly.
  Consult Documentation: Refer to SAP documentation or notes related to the RW014 error for any specific guidance or patches that may address the issue.
