Nesting computed fields

Computed fields can sometimes act as building blocks for other computed fields.

These are referred to as intermediate computations. Currently the IBM OpenPages® with Watson™ application does not support intermediate calculation definitions. If you want to reference another computed field, you must replicate the equation used in that computed field inside the equation for the current field.

For example, if we have a computed field A and define it as A = B × C and we also know C = D + E, we would only create one computed field A in the application where the equation would be B × (D + E).

While this approach can be verbose, it is sometimes the simplest.
