  The SAP error message DDLS374 indicates that there is a type mismatch for a parameter in a function module or method. This error typically occurs when the data type of the parameter being passed does not match the expected data type defined in the function module or method signature.
  Cause:
  
  Type Mismatch: The parameter being passed to the function has a different data type than what the function expects. For example, if the function expects an integer but receives a string, this error will occur.

  Solution:
  
  Check Parameter Types: Review the function module or method definition to confirm the expected data types for each parameter. Ensure that the data types of the variables you are passing match the expected types.
  Data Type Conversion: If necessary, perform explicit type conversion to ensure that the data being passed matches the expected type. For example, you can use ABAP statements like CONVERT or CAST to change the data type.
  Update Calling Program: If the function module has been changed, update the calling program to ensure that it adheres to the new parameter types.
  Debugging: Use the ABAP debugger to step through the code and inspect the values and types of the parameters being passed to the function. This can help identify where the mismatch is occurring.
