• What is the cause and solution for SAP error message 64428 - Error in exch.rate translation from &1 to &2 at rate type &3 (overflow) ?

  The SAP error message 64428 indicates an issue with exchange rate translation, specifically an overflow error when converting currency from one type to another. This typically occurs when the system attempts to perform a currency conversion that results in a value exceeding the maximum limit that can be handled by the data type used in the calculation.
  Cause:
  
  
  Overflow in Calculation: The error usually arises when the result of the currency conversion exceeds the maximum value that can be stored in the relevant data field. This can happen if:
  
  The exchange rate is set too high.
  The amount being converted is excessively large.
  There is a misconfiguration in the exchange rate type or the currency settings.
  
  
  
  Incorrect Exchange Rate Type: The exchange rate type specified may not be appropriate for the transaction, leading to incorrect calculations.
  
  
  Data Type Limitations: The data type used for storing currency values may have limitations that are being exceeded during the conversion process.
  
  
  Solution:
  
  
  Check Exchange Rates: Review the exchange rates defined in the system for the specified rate type (&3). Ensure that they are set correctly and are within reasonable limits.
  
  
  Review Transaction Amounts: Check the amounts being converted. If they are excessively large, consider whether they are correct or if they need to be adjusted.
  
  
  Adjust Data Types: If the issue is related to data type limitations, consider reviewing the data types used in the relevant calculations. This may involve working with your SAP technical team to ensure that the data types can handle the expected range of values.
  
  
  Use Different Rate Type: If the current exchange rate type is causing issues, try using a different rate type that may not lead to overflow.
  
  
  SAP Notes and Support: Check for any relevant SAP Notes that may address this specific error. Sometimes, SAP releases patches or updates that resolve known issues.
  
  
  Testing: After making adjustments, perform tests to ensure that the error no longer occurs and that currency conversions are processed correctly.
