185  *
186  * The acq.ordered_funding_source_credit view is a prioritized
187  * ordering of funding source credits.  When ordered by the first
188  * three columns, this view defines the order in which the various
189  * credits are to be tapped for spending, subject to the allocations
190  * in the acq.fund_allocation table.
191  *
192  * The first column reflects the principle that we should spend
193  * money with deadlines before spending money without deadlines.
194  *
195  * The second column reflects the principle that we should spend the
196  * oldest money first.  For money with deadlines, that means that we
197  * spend first from the credit with the earliest deadline.  For
198  * money without deadlines, we spend first from the credit with the
199  * earliest effective date.
200  *
201  * The third column is a tie breaker to ensure a consistent
202  * ordering.

1151 ) RETURNS VOID AS $$
1152 /* -------------------------------------------------------------------------------
1153
1154 Function to transfer money from one fund to another.
1155
1156 A transfer is represented as a pair of entries in acq.fund_allocation, with a
1157 negative amount for the old (losing) fund and a positive amount for the new
1158 (gaining) fund.  In some cases there may be more than one such pair of entries
1159 in order to pull the money from different funding sources, or more specifically
1160 from different funding source credits.  For each such pair there is also an
1161 entry in acq.fund_transfer.
1162
1163 Since funding_source is a non-nullable column in acq.fund_allocation, we must
1164 choose a funding source for the transferred money to come from.  This choice
1165 must meet two constraints, so far as possible:
1166
1167 1. The amount transferred from a given funding source must not exceed the
1168 amount allocated to the old fund by the funding source.  To that end we
1169 compare the amount being transferred to the amount allocated.
1170
1171 2. We shouldn't transfer money that has already been spent or encumbered, as
1172 defined by the funding attribution process.  We attribute expenses to the
1173 oldest funding source credits first.  In order to avoid transferring that
1174 attributed money, we reverse the priority, transferring from the newest funding
1175 source credits first.  There can be no guarantee that this approach will
1176 avoid overcommitting a fund, but no other approach can do any better.
1177
1178 In this context the age of a funding source credit is defined by the
1179 deadline_date for credits with deadline_dates, and by the effective_date for
1180 credits without deadline_dates, with the proviso that credits with deadline_dates
1181 are all considered "older" than those without.
1182
1183 ----------
1184
1185 In the signature for this function, there is one last parameter commented out,
1186 named "funding_source_in".  Correspondingly, the WHERE clause for the query
1187 driving the main loop has an OR clause commented out, which references the
1188 funding_source_in parameter.
1189
1190 If these lines are uncommented, this function will allow the user optionally to
1191 restrict a fund transfer to a specified funding source.  If the source
1192 parameter is left NULL, then there will be no such restriction.
