Begin Date
This field identifies a begin date for a particular expense plan entry. This field is required.
Each unique expense type cannot be included in more than one expense plan entry (having an overlapping date range) on the same project or task.
Note that if the Link Expense Plan Dates to Project / Task Dates option is checked, the Expense Plan dates are derived from the project (or task) dates (depending on whether the assignments are managed at the project or task level for this project) and cannot be directly entered on an Expense Plan entry.
