Koha::EDI
Module exporting subroutines used in EDI processing for Koha
Subroutines called by batch processing to handle Edifact messages of various types and related utilities
These routines should really be methods of some object. get_edifact_ean is a stopgap which should be replaced
process_quote(quote_message); passed a message object for a quote, parses it creating an order basket and orderlines in the database updates the message's status to received in the database and adds the link to basket
    process_invoice(invoice_message)
    passed a message object for an invoice, add the contained invoices
    and update the orderlines referred to in the invoice
    As an Edifact invoice is in effect a despatch note this receipts the
    appropriate quantities in the orders
    no meaningful return value
     process_ordrsp(ordrsp_message)
     passed a message object for a supplier response, process the contents
     If an orderline is cancelled cancel the corresponding orderline in koha
     otherwise record the supplier message against it
     no meaningful return value
    create_edi_order( { parameter_hashref } )
    parameters must include basketno and ean
    branchcode can optionally be passed
    returns 1 on success undef otherwise
    if the parameter noingest is set the formatted order is returned
    and not saved in the database. This functionality is intended for debugging only
    receipt_items( schema_obj, invoice_line, ordernumber)
    receipts the items recorded on this invoice line
    no meaningful return
    transfer_items(schema, invoice_line, originating_order, receiving_order)
    Transfer the items covered by this invoice line from their original
    order to another order recording the partial fulfillment of the original
    order
    no meaningful return
    $ean = get_edifact_ean();
    routine to return the ean.
     quote_item(lineitem, quote_message);
      Called by process_quote to handle an individual lineitem
     Generate the biblios and items if required and orderline linking to them
     Returns 1 on success undef on error
     Most usual cause of error is a line with no or incorrect budget codes
     which woild cause order creation to abort
     If other correct lines exist these are processed and the erroneous line os logged
      classmark = title_level_class(edi_item)
      Trys to return a title level classmark from a quote message line
      Will return a dewey or lcc classmark if one exists according to the
      value in DefaultClassificationSource syspref
      If unable to returns the shelfmark or classification from the GIR segment
      If all else fails returns empty string
       marc_record_obj = _create_bib_from_quote(lineitem, quote)
       Returns a MARC::Record object based on the  info in the quote's lineitem
       item_hashref = _create_item_from_quote( lineitem, quote)
       returns a hashref representing the item fields specified in the quote
      _get_invoiced_price(line_object)
      Returns the net price or an equivalent calculated from line cost / qty
      ecost = _discounted_price(discount, item_price)
