This answer applies to PDWare Portfolio versions 188.8.131.52 and later. Earlier versions provide only highlighting on out of bounds requests. The Status field has gray fill if a request has data outside the current Get Data period range. For example, if a request was submitted with demand in June this year and you get data starting in September this year, the request has out of bounds data.
If there are any out of bounds requests on a Request sheet, a right click menu, Show Out of Bounds Dates, is visible.
The command displays the early demand date in column 1, the late date in column 2 for each such request and displays the earliest early date and the latest late date in a dialog.
