Regular and External Users on all paid accounts can use date roll up. Date roll up is an experimental feature and as a result, it: may have bugs, is subject to change, and may be discontinued at any time. Please feel free to use the feedback links in Wrike Labs to share your thoughts on this beta feature.
By default, start and end dates for all items within Wrike are completely independent. For example, if you have a Task with Subtasks - the Task and its Subtasks can have different dates (they are not automatically aligned). The same holds true for Project dates and the dates of Tasks within it.
From the Gantt Chart you can roll up dates. Rolling up dates means that: a top-level item’s dates are based on the dates of items within it. When you roll up dates
Date roll up is available for Regular and External Users on all paid accounts. Enable it for your individual account.
You can now roll up dates on the Gantt Chart in your Workspace.
To roll up an item's dates:
The parent Task or Project’s dates change and are rolled up from the items within it.
To roll up dates for all items within a branch*:
Wrike starts rolling up dates starting from the bottom up. Dates are progressively rolled up for items higher up in the branch until the dates on the parent Task or Project selected in step 2 are rolled up.
*A branch includes all items nested within one item. For example, a Project could have Tasks, Subtasks, Subprojects, etc.
