Add or Delete Function Arguments
Some MapForce built-in functions are extendable, in the sense that you can add as many parameters to them as required by the context. A good example of such a function is concat, where you can add as parameters all the strings that you need concatenated.
To add or delete function arguments (for functions that support such behaviour):
•Click Add parameter ( ) or Delete parameter ( ) next to the parameter you want to add or delete, respectively.
Dropping a connection on the symbol automatically adds the parameter and connects it.
