  Solution:
  
  Check Document Status: Verify the status of the original invoice. If it has already been processed in CO-PA, you may need to handle the reversal differently.
  Manual Adjustment: Instead of reversing the invoice, consider making a manual adjustment entry in CO-PA to correct the profitability analysis.

  Use Alternative Transactions: If the reversal cannot be processed, consider using alternative transactions or methods to adjust the financial records without directly reversing the invoice.
