● The linked steps retain their step ID from the subproject, in which a namespace is added
in the main project for each link, in order to ensure unambiguous identification.
The ID namespace is automatically assigned during configuration. This also prevents an
ID namespace from being assigned twice.
The ID namespace can be changed by the user.
● A defined namespace in a main project only applies for precisely one link step (blue) with
the steps located below it (gray). Thus, the step ID does not have to be changed in the
main project or subproject.
● Identical step IDs in the main project and subproject are also possible and permitted.
● Existing queries of the step ID (Step configuration) do not have to be adapted in the main
project and subproject.
● The linked steps can be recognized in the logbook by a step ID with namespace.
● Steps with namespace before the step ID cannot be linked and cannot contain any linked
steps as substeps.
● The execution of the dialogs (in the project folder) is performed exclusively in the main
project (MP) also for the steps inserted in the "Steps" tab.
Only the step tree is linked or taken over from the subproject(s).
● The system variables used in the linked steps of the subproject (SP) always refer to the
main project (MP).
Note
Exceptions are:
● Up.$Step[ID]
● Up.$Dialog.StepSelection.CurrentID (see also System variables for the "Step
The system variables can be used for the main project and the subproject.
● The Up script variables are globally applicable in the main project and subproject.
● 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 at "Manage in".
● For the main project, not only must the subproject be reachable, but also its components
located at the linked steps.
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
