The work context

The work context is determined by the instance from which you enter a network of relationships between instances. This context is defined by the design build path of the project that this instance belongs to.

This project constitutes the starting point for the resolution of the links between instances. If a link is not resolved in the project, the projects hierarchy declared in the design build path is explored in an upward direction to resolve it.

If you open or generate an instance from its definition project, then its work context is its definition project. However, if you open or generate a calling instance, its work context is the context of the calling instance.

The links (super references or subreferences) resolve differently according to the work context.
Example: A Data Element that is called in the -CE Lines of a Segment is redefined in a lower-level project. If the work context is the project of the Segment, the Data Element that is resolved by the link is the Data Element that can be accessed from the project of the Segment. However, if the work context is a project that is hierarchically lower than the project of the Segment (for example if you access the Data Element through the Screen that calls it in this project), the Data Element that is resolved by the link is the Data Element that is redefined in the hierarchically lower project.
You select the work context when you do the following actions:
  • Open an editor. You see the instance as it is defined in the current work context. This context is displayed in the General Information of the Overview tab of each editor. The project that constitutes the work context and the projects declared higher in the hierarchy can be viewed by clicking Hierarchy.
    The same instance can be opened in two different work contexts. So it can simultaneously be displayed in two editors. However, since it is the same instance, any modification that is made in one work context is immediately available in the other work context.
    Example: Project PROJ.A is declared higher than project PROJ.B in the design build path of the location. A Data Element is defined in PROJ.A and is called by a Segment in PROJ.B.

    You can open the Data Element directly from PROJ.A, or you can access it from the Segment in PROJ.B. In this case, two editors are simultaneously available for the Data Element. These editors display the same information. Only the work context differs. The search for the Data Element super references differs if this Data Element is used by different instances in the two projects.

  • Start generating. The work context of the entry point into the generation process (usually the context of the program to be generated) is passed on to all the instances that are involved in the generation.
