  The SAP error message BP423 ("Values in a different currency have already been entered") typically occurs in the context of Business Partner (BP) data management or when dealing with financial transactions in SAP. This error indicates that there is a mismatch in the currency used for the transaction or data entry compared to what has already been recorded in the system.
  Cause:
  
  Currency Mismatch: The primary cause of this error is that the system has detected that a value has already been entered in a different currency than the one currently being used for the transaction or entry.

  Check Existing Entries: Review the existing entries for the business partner or transaction to identify the currency that has already been used. Ensure that any new entries are made in the same currency.
  Use the Correct Currency: When entering new values, make sure to select the correct currency that matches the existing entries. If you need to enter values in a different currency, you may need to adjust the existing entries first.
  Currency Conversion: If necessary, convert the values to the correct currency before entering them into the system. This may involve using exchange rates to ensure accuracy.
  Review Configuration: If the issue persists, review the configuration settings related to currency handling in the SAP system. This may involve consulting with a system administrator or SAP consultant to ensure that the settings align with your business processes.
