Subprojects in Spreadsheet Views
In a spreadsheet view (or in the spreadsheet pane of a barchart view), you can convert an activity into an internal subproject by adding an activity with an ID that indicates that it is a child of the subproject.
For example, if the project contains an activity ACT01, adding the activity ACT01.1 to the project automatically converts ACT01 into an internal subproject.
To control the display of subprojects and their children, you can use the outlining feature of spreadsheet views to display project information hierarchically.
In a spreadsheet view using outlining, subprojects display with a plus (+) sign or a minus (-) sign on the outlining button to the left of the row. If the outlining button displays a plus sign, you can expand the subproject to see more detailed information. If the outlining button displays a minus sign, the subproject is already completely expanded; clicking the outlining button collapses the subproject in this case.
Indented and Outdented Hierarchical IDs
The indent feature enables you to quickly renumber hierarchical IDs while in a spreadsheet view. When you use this feature, Open Plan renumbers the relevant ID according to the rules for automatic numbering.
The outdent feature enables you to promote an ID in a hierarchy to the level of its parent. In assigning an ID to an outdented element, Open Plan follows the rules for automatic numbering.
