936 Function to transfer money from one fund to another.
938 A transfer is represented as a pair of entries in acq.fund_allocation, with a
939 negative amount for the old (losing) fund and a positive amount for the new
940 (gaining) fund. In some cases there may be more than one such pair of entries
941 in order to pull the money from different funding sources, or more specifically
942 from different funding source credits. For each such pair there is also an
943 entry in acq.fund_transfer.
945 Since funding_source is a non-nullable column in acq.fund_allocation, we must
946 choose a funding source for the transferred money to come from. This choice
947 must meet two constraints, so far as possible:
949 1. The amount transferred from a given funding source must not exceed the
950 amount allocated to the old fund by the funding source. To that end we
951 compare the amount being transferred to the amount allocated.
953 2. We shouldn't transfer money that has already been spent or encumbered, as
954 defined by the funding attribution process. We attribute expenses to the
955 oldest funding source credits first. In order to avoid transferring that
956 attributed money, we reverse the priority, transferring from the newest funding
957 source credits first. There can be no guarantee that this approach will
958 avoid overcommitting a fund, but no other approach can do any better.
960 In this context the age of a funding source credit is defined by the
961 deadline_date for credits with deadline_dates, and by the effective_date for
962 credits without deadline_dates, with the proviso that credits with deadline_dates
963 are all considered "older" than those without.
967 In the signature for this function, there is one last parameter commented out,
968 named "funding_source_in". Correspondingly, the WHERE clause for the query
969 driving the main loop has an OR clause commented out, which references the
970 funding_source_in parameter.
972 If these lines are uncommented, this function will allow the user optionally to
973 restrict a fund transfer to a specified funding source. If the source
974 parameter is left NULL, then there will be no such restriction.
