Transformer’s interface offers an integrated set of useful functions, which are used to perform a variety of operations, such as calculation and manipulation of input data, or retrieving data from a database. You may use functions to modify the output node value to match your requirements. You can build complex expressions for output values using the combinations of functions via the Output Node Mapping Builder.

In addition, Transformer enables you to implement your own algorithms for producing output values by adding custom functions according to the specific format. For more information, see Custom Functions.
