Hi Anna
Sorry, I meant "Throw" a function module in front.
As the BOL Model in use maybe large...and yet you may only want to make use of a small number of the fields, by using the function module you can define the input fields required, any validations required on those fields, etc. Then call the BOL Model to perform the function you require.
Function Module can then also structure the response (return parameters) you require.
