BF#C F# Cash Position Upate
Introuction
The BFXC, FX Cash Position Update batch task is used to update the
foreign exchange trader currency pair position using all debit/credit
amounts for the foreign exchange cash general ledger account created
from journal entries or accounting tasks that do not directly update
trader position.
The BFXC, FX Cash Position Update task is run in the nightly batch
Moifications
BFXC will be modified to include a new text box that will allow the
user to specify a currency with which BFXC will disaggregate the cash
position.
When a currency is entered, BFXC will do the following
Use existing logic to calculate the foreign currency against
base currency position.
Retrieve the Spot Revaluation Rates from the REVP table
Calculate the rate for each currency against that specified on
the BFXC disaggregate currency field using the spot
revaluation rates.
Calculate the disaggregate amounts and create the position
updates for each disaggregate currency pair using thecorresponding Cash Position trader, portfolio and cost center
on the CCYP table.

Normally, when the checkbox Use Implied Spot Rate from ACUPs
is checked then BFXC calculates the conversion rate to use from the
currency amount against the base equivalent. In this example, BFXC
would produce the following CPPR update

AUD GBP TRAD

PORT1 1000 3 Jul 2001 347,367.11 -125,000 2.77893688
However, the user has specified a disaggregate currency of USD.
Instead of posting just the AUD/GBP position as above BFXC will
now calculate and post a AUD/USD, CPPR.CCY1 against
disaggregation currency, and a GBP/USD position, CPPR.CCY2
against disaggregation
The AUD/USD (CCY1 against Disaggregation currency) rate is
calculated using the spot revaluation rates from the REVP table.
AUD/USD rate = 0.5080
The GBP/USD (CCY2 against Disaggregation currency) rate is
calculated using the AUD/USD and AUD/GBP rates, so
GBP/USD rate = GBP/AUD x AUD/USD
= 2.77893688 x 0.5080 = 1.41169993504
BFXC will always use the REVP rate to calculate the base currency
against the disaggregation currency whether the base is CCY1 orCCY2. BFXC will then use that rate in conjunction with the rate used
for the foreign currency against base currency to calculate the foreign
currency against disaggregation currency rate.

The trader, portfolio and cost center that BFXC posts to are those from
the CCYP of the disaggregate currency pair not the currency against
base pair.
When the checkbox Use Implied Spot Rate from ACUPs is not
checked then BFXC uses the REVP spot rate for the currency against
base, this will not change. However, BFXC will now use that rate to
calculate the rate for the base against disaggregate currency.
