=head1 NAME

SL::DB::Order - Order Datenbank Objekt.

=head1 FUNCTIONS

=head2 C<type>

Returns one of the following string types:

=over 4

=item sales_order

=item purchase_order

=item sales_quotation

=item request_quotation

=back

=head2 C<is_type TYPE>

Returns true if the order is of the given type.

=head2 C<convert_to_delivery_order %params>

Creates a new delivery order with C<$self> as the basis by calling
L<SL::DB::DeliveryOrder::new_from>. That delivery order is saved, and
C<$self> is linked to the new invoice via
L<SL::DB::RecordLink>. C<$self>'s C<delivered> attribute is set to
C<true>, and C<$self> is saved.

The arguments in C<%params> are passed to
L<SL::DB::DeliveryOrder::new_from>.

Returns C<undef> on failure. Otherwise the return value depends on the
context. In list context the new delivery order and a shipto instance
will be returned. In scalar instance only the delivery order instance
is returned.

Custom shipto addresses (the ones specific to the sales/purchase
record and not to the customer/vendor) are only linked from C<shipto>
to C<delivery_orders>. Meaning C<delivery_orders.shipto_id> will not
be filled in that case. That's why a separate shipto object is created
and returned.

=head2 C<convert_to_invoice %params>

Creates a new invoice with C<$self> as the basis by calling
L<SL::DB::Invoice::new_from>. That invoice is posted, and C<$self> is
linked to the new invoice via L<SL::DB::RecordLink>. C<$self>'s
C<closed> attribute is set to C<true>, and C<$self> is saved.

The arguments in C<%params> are passed to L<SL::DB::Invoice::post>.

Returns the new invoice instance on success and C<undef> on
failure. The whole process is run inside a transaction. On failure
nothing is created or changed in the database.

At the moment only sales quotations and sales orders can be converted.

=head2 C<create_sales_process>

Creates and saves a new sales process. Can only be called for sales
orders.

The newly created process will be linked bidirectionally to both
C<$self> and to all sales quotations that are linked to C<$self>.

Returns the newly created process instance.
