  The SAP error message FDM_MIRROR012 indicates that there is an issue with the creation or synchronization of contact persons in the FI (Financial Accounting) customer master data. Specifically, it suggests that the contact persons you are trying to create already exist in the system.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the contact person you are trying to add already exists in the customer master data. This could be due to a previous entry that was not properly deleted or a synchronization issue between systems.

  If the existing contact person is no longer needed, you can delete them.
  
  
  
  Data Validation: 
  
  Ensure that the data you are trying to upload or create does not contain duplicates. Implement data validation checks before performing mass uploads or migrations.
