+=head1 NAME
+
+SL::Controller::BankTransaction - Posting payments to invoices from
+bank transactions imported earlier
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item C<save_single_bank_transaction %params>
+
+Takes a bank transaction ID (as parameter C<bank_transaction_id> and
+tries to post its amount to a certain number of invoices (parameter
+C<invoice_ids>, an array ref of database IDs to purchase or sales
+invoice objects).
+
+This method handles already partly assigned bank transactions.
+
+This method cannot handle already partly assigned bank transactions, i.e.
+a bank transaction that has a invoice_amount <> 0 but not the fully
+transaction amount (invoice_amount == amount).
+
+If the amount of the bank transaction is higher than the sum of
+the assigned invoices (1 .. n) the bank transaction will only be
+partly assigned.
+
+The whole function is wrapped in a database transaction. If an
+exception occurs the bank transaction is not posted at all. The same
+is true if the code detects an error during the execution, e.g. a bank
+transaction that's already been posted earlier. In both cases the
+database transaction will be rolled back.
+
+If warnings but not errors occur the database transaction is still
+committed.
+
+The return value is an error object or C<undef> if the function
+succeeded. The calling function will collect all warnings and errors
+and display them in a nicely formatted table if any occurred.
+
+An error object is a hash reference containing the following members:
+
+=over 2
+
+=item * C<result> — can be either C<warning> or C<error>. Warnings are
+displayed slightly different than errors.
+
+=item * C<message> — a human-readable message included in the list of
+errors meant as the description of why the problem happened
+
+=item * C<bank_transaction_id>, C<invoice_ids> — the same parameters
+that the function was called with
+
+=item * C<bank_transaction> — the database object
+(C<SL::DB::BankTransaction>) corresponding to C<bank_transaction_id>
+
+=item * C<invoices> — an array ref of the database objects (either
+C<SL::DB::Invoice> or C<SL::DB::PurchaseInvoice>) corresponding to
+C<invoice_ids>
+
+=back
+
+=item C<action_unlink_bank_transaction>
+
+Takes one or more bank transaction ID (as parameter C<form::ids>) and
+tries to revert all payment bookings including already cleared bookings.
+
+This method won't undo payments that are in a closed period and assumes
+that payments are not manually changed, i.e. only imported payments.
+
+GL-records will be deleted completely if a bank transaction was the source.
+
+TODO: we still rely on linked_records for the check boxes
