  The SAP error message FQ479 indicates that there is an issue with the assignment of a customer to a subledger account in the financial accounting module. This error typically arises when there is an attempt to create or modify an assignment that already exists in the system.
  Cause:
  
  Duplicate Assignment: The most common cause of this error is that the customer is already assigned to the specified subledger account. SAP does not allow duplicate assignments for the same customer and subledger account combination.

  Data Consistency Check:
  
  Run data consistency checks to identify any potential issues with the customer or subledger account data. This can be done using transaction codes like SARA for archiving or SE16 for data browsing.
