  The SAP error message FINS_CFIN_AC_DOC091 indicates that there is a problem with the uniqueness of a reference for a sender item in the context of Central Finance (CFIN). This error typically arises during the data transfer process from a source system to the Central Finance system, where the system expects a unique reference for a specific combination of company code, fiscal year, and document number.

  Company Code (CC): The company code in question.

  Correct Duplicates:
  
  Once identified, you need to determine which entries are valid and which are duplicates. You may need to delete or adjust the duplicate entries in the source system to ensure that each reference is unique.
  
  
  
  Check Configuration:
  
  Review the configuration settings in the source system to ensure that the uniqueness of document references is enforced. This may involve checking the settings for document types and number ranges.
  
  
  
  Reprocess the Data:
  
  After correcting the duplicates, reprocess the data transfer to the Central Finance system. Ensure that the data is correctly replicated without duplicates.
