  The SAP error message FKKBIX2018, which states "Duplicate entry cannot be adjusted," typically occurs in the context of financial accounting, particularly when dealing with document postings or adjustments in the SAP system. This error indicates that there is an attempt to adjust a financial entry that has already been recorded, and the system has identified it as a duplicate.
  Causes:
  
  Duplicate Document Entries: The most common cause is that there are multiple entries in the system that are identical or have the same reference number, leading to a conflict when trying to adjust one of them.
  Incorrect Posting Logic: The logic used to post or adjust entries may inadvertently create duplicates, especially if the same transaction is processed multiple times.
  Data Integrity Issues: There may be issues with data integrity, such as inconsistencies in the database or problems with the way transactions are recorded.
  Configuration Issues: Incorrect configuration settings in the financial module can lead to duplicate entries being allowed or not being properly managed.
  
  Solutions:
  
  Identify Duplicate Entries: Use transaction codes like FB03 (Display Document) or FBL1N (Vendor Line Item Display) to review the entries and identify duplicates. Check for entries with the same document number, date, and amount.
  Delete or Reverse Duplicates: If duplicates are found, you may need to delete or reverse the duplicate entries. This can be done using transaction codes like FB08 (Reverse Document) or FBRA (Reset Cleared Items).
  Adjust Posting Logic: Review the posting logic and ensure that transactions are not being processed multiple times. Implement checks to prevent duplicate postings.
  Check Configuration Settings: Review the configuration settings in the financial module to ensure that they are set up correctly to handle document postings and adjustments.
