Call

The Call element provides a graphical representation of the 'call' expression and calls out to a static Java method to perform a complex calculation. The new argument can be added to the Call element. Other palette elements, for example, Date, Period Length or Rule Reference can be added to the argument of the Call element. The Period Length element can be added to other palette elements, for example, Create.

CAUTION:

Since Cúram V6, CER and the Dependency Manager support the automatic recalculation of CER-calculated values if their dependencies change.

If you change the implementation of a static method, CER and the Dependency Manager will not automatically know to recalculate attribute values that were calculated using the old version of your static method.

Once a static method has been used in a production environment for stored attribute values, rather than changing the implementation you should instead create a new static method (with the required new implementation), and change your rule sets to use the new static method. When you publish your rule set changes to point to the new static method, CER and the Dependency Manager will automatically recalculate all instances of the affected attribute values.
