698 =item C<new_from $source, %params>
700 Creates a new C<SL::DB::Invoice> instance and copies as much
701 information from C<$source> as possible. At the moment only sales
702 orders and sales quotations are supported as sources.
704 The conversion copies order items into invoice items. Dates are copied
705 as appropriate, e.g. the C<transdate> field from an order will be
706 copied into the invoice's C<orddate> field.
708 C<%params> can include the following options:
714 An optional array reference of RDBO instances for the items to use. If
715 missing then the method C<items_sorted> will be called on
716 C<$source>. This option can be used to override the sorting, to
717 exclude certain positions or to add additional ones.
719 =item C<skip_items_negative_qty>
721 If trueish then items with a negative quantity are skipped. Items with
722 a quantity of 0 are not affected by this option.
724 =item C<skip_items_zero_qty>
726 If trueish then items with a quantity of 0 are skipped.
730 An optional code reference that is called for each item with the item
731 as its sole parameter. Items for which the code reference returns a
732 falsish value will be skipped.
736 An optional hash reference. If it exists then it is passed to C<new>
737 allowing the caller to set certain attributes for the new invoice.
738 For example to set a different transdate (default is the current date),
739 call the method like this:
742 $params{attributes}{transdate} = '28.08.2015';
743 $invoice = SL::DB::Invoice->new_from($self, %params)->post || die;
747 Amounts, prices and taxes are not
748 calculated. L<SL::DB::Helper::PriceTaxCalculator::calculate_prices_and_taxes>
749 can be used for this.
751 The object returned is not saved.
753 =item C<post %params>
755 Posts the invoice. Required parameters are:
761 The ID of the accounts receivable chart the invoice's amounts are
762 posted to. If it is not set then the first chart configured for
763 accounts receivables is used.
767 This function implements several steps:
771 =item 1. It calculates all prices, amounts and taxes by calling
772 L<SL::DB::Helper::PriceTaxCalculator::calculate_prices_and_taxes>.
774 =item 2. A new and unique invoice number is created.
776 =item 3. All amounts for costs of goods sold are recorded in
779 =item 4. All amounts for parts, services and assemblies are recorded
780 in C<acc_trans> with their respective charts. This is determined by
781 the part's buchungsgruppen.
783 =item 5. The total amount is posted to the accounts receivable chart
784 and recorded in C<acc_trans>.
786 =item 6. Items in C<invoice> are updated according to their allocation
787 status (regarding costs of goods sold). Will only be done if
788 kivitendo is not configured to use Einnahmenüberschussrechnungen.
790 =item 7. The invoice and its items are saved.
794 Returns C<$self> on success and C<undef> on failure. The whole process
795 is run inside a transaction. If it fails then nothing is saved to or
796 changed in the database. A new transaction is only started if none are
799 =item C<basic_info $field>
801 See L<SL::DB::Object::basic_info>.
805 Returns 1 or 0, depending on whether the invoice is closed or not. Currently
806 invoices that are overpaid also count as closed and credit notes in general.
808 =item C<recalculate_amounts %params>
810 Calculate and set amount and netamount from acc_trans objects by summing up the
811 values of acc_trans objects with AR_amount and AR_tax link charts.
812 amount and netamount are set to the calculated values.
814 =item C<validate_acc_trans>
816 Checks if the sum of all associated acc_trans objects is 0 and checks whether
817 the amount of the AR acc_transaction matches the AR amount. Only the first AR
818 line is checked, because the sum of all AR lines is 0 for paid invoices.
822 Can be called with a debug parameter which writes debug info to STDOUT, which is
823 useful in console mode or while writing tests.
825 my $ar = SL::DB::Manager::Invoice->get_first();
826 $ar->validate_acc_trans(debug => 1);
828 =item C<create_ar_row %params>
830 Creates a new acc_trans entry for the receivable (AR) entry of an existing AR
831 invoice object, which already has some income and tax acc_trans entries.
833 The acc_trans entry is also returned inside an array ref.
839 =item * chart as an RDBO object, e.g. for bank. Must be a 'paid' chart.
843 Currently the amount of the invoice object is used for the acc_trans amount.
844 Use C<recalculate_amounts> before calling this method if amount isn't known
845 yet or you didn't set it manually.
847 =item C<add_ar_amount_row %params>
849 Add a new entry for an existing AR invoice object. Creates an acc_trans entry,
850 and also adds an acc_trans tax entry, if the tax has an associated tax chart.
851 Also all acc_trans entries that were created are returned inside an array ref.
857 =item * chart as an RDBO object, should be an income chart (link = AR_amount)
865 =item C<mark_as_paid>
867 Marks the invoice as paid by setting its C<paid> member to the value of C<amount>.
873 As explained in the new_from example, it is possible to set transdate to a new value.
874 From a user / programm point of view transdate is more than holy and there should be
875 some validity checker available for controller code. At least the same logic like in
876 Form.pm from ar.pl should be available:
877 # see old stuff ar.pl post
878 #$form->error($locale->text('Cannot post transaction above the maximum future booking date!'))
879 # if ($form->date_max_future($transdate, \%myconfig));
880 #$form->error($locale->text('Cannot post transaction for a closed period!')) if ($form->date_closed($form->{"transdate"}, \%myconfig));
