You work for a consulting firm in the infrastructure sector that collects data on the forces that weather phenomena exert on different locations in the architecture of a building. You want to use a dynamic mapping to transform the data that you collect and round the value of the force that is exerted.

In the dynamic mapping, you use an Expression transformation that receives the following generated input ports:

Force_Location_A   Decimal
Force_Location_B   Decimal
Force_Location_C   Decimal

You create a port selector

Port_Selector_Force

that has a selection rule to include ports that have the prefix

Force_

. You also create a dynamic output port

Dynamic_Forces

and use an expression parameter for the dynamic expression. The default value of the expression parameter is the following expression:

CEIL(Port_Selector_Force)

You can also use the expression parameter in multiple parameter sets. For example, the default value of the expression parameter in the one parameter set might be

CEIL(Port_Selector_Force)

. In another parameter set, the default value of the expression parameter might be

FLOOR(Port_Selector_Force)

.
