• What is the cause and solution for SAP error message W8436 - Error during currency conversion '&1' -> '&2' ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W8436 - Error during currency conversion '&1' -> '&2'
  
  Meaning / Cause:
  This warning message indicates that an error occurred during the currency conversion process from currency &1 (source currency) to currency &2 (target currency). The system attempted to convert an amount from one currency to another but failed due to one or more of the following reasons:
  
  Missing exchange rate for the currency pair and date in the exchange rate table.
  Incorrect or incomplete exchange rate configuration in the system.
  The exchange rate type used for conversion is not maintained or incorrect.
  The date for the exchange rate is outside the valid range or no exchange rate exists for that date.
  The currency codes provided are invalid or not recognized by the system.
  The conversion logic or function module encountered an unexpected error.
  
  
  Common Causes in Detail:
  
  
  Exchange Rate Not Maintained:
  
  The system cannot find an exchange rate for the currency pair on the specified date. For example, if you try to convert USD to EUR on a date where no exchange rate is maintained, this error occurs.
  
  
  Incorrect Exchange Rate Type:
  
  SAP uses different exchange rate types (e.g., M for average rate, B for buying rate). If the wrong type is used or not maintained, conversion fails.
  
  
  Currency Master Data Issues:
  
  The currency codes might be incorrect or not defined in the system.
  
  
  Date Issues:
  
  The date for which the conversion is requested might be outside the valid range of the exchange rate validity period.
  
  
  Custom Code or User Exit Errors:
  
  If currency conversion is done via custom code or user exits, errors in the logic can cause this message.
  
  
  
  Solution / How to Fix:
  
  
  Check Exchange Rates:
  
  Go to transaction OB08 (Maintain Exchange Rates).
  Verify that the exchange rate between currency &1 and &2 exists for the relevant date.
  If missing, maintain the correct exchange rate.
  
  
  
  Verify Exchange Rate Type:
  
  Confirm that the exchange rate type used in the conversion is correct and maintained.
  The exchange rate type is usually passed as a parameter in the conversion function/module.
  
  
  
  Check Currency Codes:
  
  Use transaction OB22 or TCURC to verify that both currencies are valid and active.
  
  
  
  Check Validity Dates:
  
  Ensure the exchange rate is valid for the date on which conversion is attempted.
  
  
  
  Review Custom Code:
  
  If conversion is done via custom programs or user exits, debug and check for errors in the currency conversion logic.
  
  
  
  Use Standard Function Modules:
  
  SAP standard function modules like CONVERSION_EXIT_ALPHA_INPUT, CONVERSION_EXIT_ALPHA_OUTPUT, or CURRENCY_CONVERT should be used properly.
  
  
  
  Check for Notes / OSS Messages:
  
  Search SAP Notes for any known issues related to currency conversion errors.
  
  
  
  
  Additional Information:
  
  Transaction OB08: Used to maintain exchange rates.
  Function Module: CONVERSION_EXIT_ALPHA_INPUT or CURRENCY_CONVERT are commonly used for currency conversion.
  Currency Table: TCURC (Currency Codes), TCURR (Exchange Rates).
  Exchange Rate Types: M (average), B (buying), G (selling), etc.
  Date Dependency: Exchange rates are date-dependent; always check the date validity.
