  The SAP error message CNV_PE311 indicates that there is an issue with currency customizing data that has already been loaded into the system using a previous transfer method. This typically occurs during data migration or system conversion processes, particularly when using SAP's Conversion Tools or Migration Cockpit.

  Solution:
  To resolve the CNV_PE311 error, you can follow these steps:
  
  
  Check Previous Transfers: Verify if the currency customizing data has indeed been loaded previously. You can do this by checking the relevant tables (e.g., T001, TCURR) to see if the data exists.
  
  
  Delete Existing Data: If you confirm that the data has been loaded and you need to reload it (for example, due to corrections), you may need to delete the existing entries in the relevant tables. Be cautious with this step, as it may affect other processes.

  Migration Tools: Understand the specific migration tools you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) and their respective documentation.
