External Tasks

Information

• In PLANTA project, external tasks are one of the three options for illustrating dependencies between projects.
  • Two alternative options are: dependencies between projects and external links
• This function allows you to display tasks of another project in the schedule of a project/program.
• Milestones that are decisive for your own project can therefore be displayed and ensure clarity within the project.

Notes

• From a technical point of view, external tasks are links (links with activated External task parameter), but in contrast to the internal or external links, they have no effect on the dates of the own or dependent project. If one of the projects involved is calculated, the other projects are not automatically calculated as well (cf. Calculation of projects with external links).

The procedure for displaying an external task is identical in project and program schedules.

• Right-click on the required task.
• Select Insert External task from the context menu.
• Select the required project/program and the required task from the respective listbox.
  • The selected external task is displayed in the schedule of your own project/program.

	Calculated dates of the external tasks	Uncritical Critical	Calc. start and Calc end of the external tasks are calculated by clicking on the calculation button or by selecting the respective menu item. Uncritical means: Total float > 0 Critical means: Total float 0 Since in PLANTA project the setting of requested dates on tasks leads to Total float = 0, tasks that do not necessarily lie on the critical path can be critical as well.
	Calculated dates of the external summary tasks
/	Milestones/master milestones of the external summary tasks	/ Without delay / With delay	Without delay means: Total float 0 With delay means: Total float < 0
