938 SL::Controller::BankTransaction - Posting payments to invoices from
939 bank transactions imported earlier
940
941 =head1 FUNCTIONS
942
943 =over 4
944
945 =item C<save_single_bank_transaction %params>
946
947 Takes a bank transaction ID (as parameter C<bank_transaction_id> and
948 tries to post its amount to a certain number of invoices (parameter
949 C<invoice_ids>, an array ref of database IDs to purchase or sales
950 invoice objects).
951
952 The whole function is wrapped in a database transaction. If an
953 exception occurs the bank transaction is not posted at all. The same
954 is true if the code detects an error during the execution, e.g. a bank
955 transaction that's already been posted earlier. In both cases the
956 database transaction will be rolled back.
957
958 If warnings but not errors occur the database transaction is still
959 committed.
960
961 The return value is an error object or C<undef> if the function
962 succeeded. The calling function will collect all warnings and errors
963 and display them in a nicely formatted table if any occurred.
964
965 An error object is a hash reference containing the following members:
966
967 =over 2
968
969 =item * C<result> — can be either C<warning> or C<error>. Warnings are
970 displayed slightly different than errors.
971
972 =item * C<message> — a human-readable message included in the list of
973 errors meant as the description of why the problem happened
974
975 =item * C<bank_transaction_id>, C<invoice_ids> — the same parameters
976 that the function was called with
977
978 =item * C<bank_transaction> — the database object
979 (C<SL::DB::BankTransaction>) corresponding to C<bank_transaction_id>
980
981 =item * C<invoices> — an array ref of the database objects (either
982 C<SL::DB::Invoice> or C<SL::DB::PurchaseInvoice>) corresponding to
983 C<invoice_ids>
