Begin Date

This field identifies the period of performance begin date.

The begin date on the PO Summary page must be on or before any of the detail line begin dates.

For Mods, the begin date is pre-populated with the value from the original PO or latest approved PO Mod. This field must be on or before the earliest Begin Date for any Timesheet, Expense Report, or Vendor Invoice associated with the original PO. 

Note: Valid date format is M/d/yyyy.

Note: If PR lines exist in the PR document, the details grid should contain only the PR Lines where the PR Lines Period of Performance (POP) overlaps with the PO Summary POP. For example, if the POP on my PO Summary is 1/1/2017 to 1/31/2017 and the PR Line POP is 2/1/2017 to 2/28/2017, then that PR Line would not be available for selection. However, if the POP on my PO Summary is 1/1/2017 to 1/31/2017 and the PR Line POP is 1/31/2017 to 1/31/2017, then that PR Line would be available for selection. If there is at least 1 day overlap between the PR Line POP and the PO Summary POP, the PR Line is available for selection.
