The Assigning Periods selection criteria is used to specify the number of periods that will be included in the resulting grid layout. You can choose:
Period Type -- specify whether the grid will represent Days, Weeks, Semi-Month, Months, Quarters or Years.
Note that if you have enabled the Allow Creation of and Show Fiscal Calendar Options (unanet.fiscal_calendar.enabled) property, additional 'fiscal' period options will be available in the drop-down.
Fiscal periods must be established via the Admin >> Setup >> Fiscal Year screen in order to be available for use in reporting. Specific Fiscal Periods appearing in drop-down lists will be a concatenation of Fiscal Year Name w/ Accounting Period.
An additional option of "Period of Performance" is also available. When this option is selected, the resulting grid will include only a single editable field that will reflect the date range of the project/task associated with that entry.
Number -- specify the number of periodic columns to include in the resulting grid. This option is not available when using the "Period of Performance" period type.
Start Date -- specify the date of the first period (the grid/matrix will begin with the period containing this start date). This option is not available when using the "Period of Performance" period type.
