This is a library to parse MT940 and MT942 account statements. It was ported from Ruby and is based on Thies C. Arntzen's mt940 library. The MT94x category of SWIFT messages are meant for customer statements and cash management:
- MT940 is the standard structured Customer Statement Message format (end-of-day statement file which details all entries booked to a bank account). Usually you receive a customer statement message the next morning of the day of business.
- MT942 is the standard structured Interim Transaction Report format. MT942 gives a report of the debits/credits any given time of the day.
Include a dependency in your mix.exs
:
deps: [{:mt940, "~> 1.1.2"}, …]
use MT940
and parse!
the raw input:
defmodule BankAccount do
use MT940
def balance(raw) when is_binary(raw) do
%{amount: amount, currency: currency} = raw
|> parse!
|> Enum.at(-1)
|> MT940.CustomerStatementMessage.closing_balance
"#{amount} #{currency}"
end
def transactions(raw) when is_binary(raw) do
raw
|> parse!
|> Enum.flat_map(&MT940.CustomerStatementMessage.statement_lines/1)
end
end
If you want to have a more detailed, low-level list of MT940 commands, use the
MT940.Parser.parse!
command.
Find the specification in the MT940 Format Overview or in the SWIFT MT 940 Customer Statement Message Report.
