  The SAP error message FIN_RE_ABAP_ENG104 with the description "Type of runtime parameter & cannot be applied" typically occurs in the context of ABAP programming, particularly when there is a mismatch in the expected data type of a runtime parameter in a function module or method.
  Cause:
  
  Data Type Mismatch: The error usually arises when the type of a parameter being passed to a function or method does not match the expected type defined in the function or method signature.
  Incorrect Parameter Definition: If the parameter is defined incorrectly in the ABAP code or if the calling program is passing an incorrect type, this error can occur.
  Changes in Data Dictionary: If there have been recent changes to the data dictionary (like changes in data types or structures) that are not reflected in the calling program, it can lead to this error.
  
  Solution:
  
  Check Parameter Types: Review the function module or method definition to ensure that the types of the parameters being passed match the expected types. This includes checking for any discrepancies in data types (e.g., CHAR vs. NUMC).
  Update Calling Program: If the calling program is passing parameters, ensure that the parameters are being passed in the correct format and type.
  Data Dictionary Consistency: If there have been changes in the data dictionary, ensure that all dependent programs and function modules are updated accordingly. You may need to regenerate the function module or method.
  Debugging: Use the ABAP debugger to step through the code and identify where the mismatch is occurring. This can help pinpoint the exact location and cause of the error.
  Consult Documentation: If the function module or method is standard SAP, refer to the SAP documentation or notes for any known issues or updates related to that function.
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the different ABAP data types and their characteristics to avoid mismatches.
