# The checks for $form->{"ordnumber_$i"} and quo and do are for the old
# behaviour, where this data was stored in its own database fields in
# the invoice items, and there were no record links for the items.

# If this information were to be fetched in retrieve_invoice, e.g. for showing
# this information in the second row, then these fields will already have
# been set and won't be calculated again. This shouldn't be done there
# though, as each invocation creates several database calls per item, and would
# make the interface very slow for many items. So currently these
# requests are only made when printing the record.

# When using the workflow an invoice item can only be (recursively) linked to at
# most one sales quotation item and at most one delivery order item. But it may
# be linked back to several order items, if collective orders were involved. If
# that is the case we will always choose the very first order item from the
# original order, i.e. where it first appeared in an order.

# In that case there won't be any links for quo or do items either

# sales order items are fetched and sorted by id, the lowest id is first
# It is assumed that the id always grows, so the item we want (the original) will have the lowest id
# better solution: filter the order_item that doesn't have any links from other order_items
# or maybe fetch linked_records with param save_path and order by _record_length_depth
