● The same names are permitted for the components in the MP and SP.
● The properties of the step configuration ("Activation", "Activation disabled" and "Collapse")
can be alternatively managed in the main project or subproject.
Various use cases are thus supported. A subproject can thus be managed independently
of the main project if the "subproject" is selected in the main project under "Manage in".
Query steps
The queries in the main project, which concern a linked step in the subproject, are only
expanded by the specification of the namespace.
In the subproject, steps of the main project can be queried by specifying the namespace "."
(period).
If the subproject runs separately, the specification of the namespace "." is for a return value
"Null". This implementation ensures that a step query always refers clearly to one and the
same step, in this case for "." in the main project. This must be taken into account in the
programming.
Example for step query
The following shows how a query can be made whether the steps are active. The status in the
relation of the projects to one another is either a main project (MP, black) or a subproject (SP,
gray).
HP_Step1
If Up.$Step[2].Activated == true
If Up.$Step[OP19.2].Activated == true
HP_Step2
UP_Step1
If Up.$Step[2].Activated == true
If Up.$Step[.2].Activated == true
