• What is the cause and solution for SAP error message FMCA_BRF101 - Expression &1 must be result category 'Currency Amount' ?

  The SAP error message FMCA_BRF101 indicates that there is an issue with the expression in a Business Rule Framework (BRF) application where the expected result category is 'Currency Amount', but the expression does not meet this requirement. This error typically arises in scenarios where financial calculations or currency-related logic are being implemented.
  Cause:
  
  Incorrect Expression Type: The expression defined in the BRF does not return a value of the type 'Currency Amount'. This could happen if the expression is returning a different data type, such as a string, integer, or decimal without the currency context.
  Data Type Mismatch: The data type of the variables or constants used in the expression may not be compatible with the expected 'Currency Amount' type.
  Configuration Issues: There may be misconfigurations in the BRF rules or expressions that lead to this mismatch.
  
  Solution:
  
  Check Expression Definition: Review the expression that is causing the error. Ensure that it is defined to return a 'Currency Amount'. You may need to adjust the logic or the data types used in the expression.
  Use Currency Data Types: Ensure that any variables or constants used in the expression are defined as currency types. In SAP, this often involves using specific data types that are recognized as currency.
  Modify Result Category: If the logic does not need to return a currency amount, consider changing the expected result category of the expression to match the actual return type. However, this should be done with caution, as it may affect the overall logic of the application.
  Testing: After making changes, test the expression to ensure that it now returns the correct type and that the error is resolved.
