When ordered by the first * three columns, this view defines the order in which the various * credits are to be tapped for spending, subject to the allocations * in the acq.fund_allocation table. * * The first column reflects the principle that we should spend * money with deadlines before spending money without deadlines. * * The second column reflects the principle that we should spend the * oldest money first. For money with deadlines, that means that we * spend first from the credit with the earliest deadline. For * money without deadlines, we spend first from the credit with the * earliest effective date. * * The third column is a tie breaker to ensure a consistent * ordering. * * **** * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * as published by the Free Software Foundation; either version 2 * of the License, or (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
