Rules formulas Sum

The settings

The setting pattern for a sum

The settings that must be used to make formulas are the settings that end with "-s"

Scenario 1

Settings ending with "-s" should be used only for sum formulas.  So settings with "-s" are only used to add values to carry the sum over to the parents.

Scenario 2

The formula of a child that uses a parent, must NOT use a variable with an "-s" .

Scenario 3

This means that if the compilation is only for children, the compilation variable will not have "-s".

Behaviour of disconnected settings

The disconnected settings become the Manual options except for the settings of the root item.  For these settings, mandatory tasks are created.

Optional settings

When we make a formula on an optional setting, we change the option state only when the parent is of type assembly or dimension and it is in modification.
