1065 =head1 NAME
1066
1067 Koha::EDI
1068
1069 =head1 SYNOPSIS
1070
1071    Module exporting subroutines used in EDI processing for Koha
1072
1073 =head1 DESCRIPTION
1074
1075    Subroutines called by batch processing to handle Edifact
1076    messages of various types and related utilities
1077
1078 =head1 BUGS
1079
1080    These routines should really be methods of some object.
1081    get_edifact_ean is a stopgap which should be replaced
1082
1083 =head1 SUBROUTINES
1084
1085 =head2 process_quote
1086
1087     process_quote(quote_message);
1088
1089    passed a message object for a quote, parses it creating an order basket
1090    and orderlines in the database
1091    updates the message's status to received in the database and adds the
1092    link to basket
1093
1094 =head2 process_invoice
1095
1096     process_invoice(invoice_message)
1097
1098     passed a message object for an invoice, add the contained invoices
1099     and update the orderlines referred to in the invoice
1100     As an Edifact invoice is in effect a despatch note this receipts the
1101     appropriate quantities in the orders
1102
1103     no meaningful return value
1104
1105 =head2 process_ordrsp
1106
1107      process_ordrsp(ordrsp_message)
1108
1109      passed a message object for a supplier response, process the contents
1110      If an orderline is cancelled cancel the corresponding orderline in koha
1111      otherwise record the supplier message against it
1112
1113      no meaningful return value
1114
1115 =head2 create_edi_order
1116
1117     create_edi_order( { parameter_hashref } )
1118
1119     parameters must include basketno and ean
1120
1121     branchcode can optionally be passed
1122
1123     returns 1 on success undef otherwise
1124
1125     if the parameter noingest is set the formatted order is returned
1126     and not saved in the database. This functionality is intended for debugging only
1127
1128 =head2 receipt_items
1129
1130     receipt_items( schema_obj, invoice_line, ordernumber)
1131
1132     receipts the items recorded on this invoice line
1133
1134     no meaningful return
1135
1136 =head2 transfer_items
1137
1138     transfer_items(schema, invoice_line, originating_order, receiving_order)
1139
1140     Transfer the items covered by this invoice line from their original
1141     order to another order recording the partial fulfillment of the original
1142     order
1143
1144     no meaningful return
1145
1146 =head2 get_edifact_ean
1147
1148     $ean = get_edifact_ean();
1149
1150     routine to return the ean.
1151
1152 =head2 quote_item
1153
1154      quote_item(lineitem, quote_message);
1155
1156       Called by process_quote to handle an individual lineitem
1157      Generate the biblios and items if required and orderline linking to them
1158
1159      Returns 1 on success undef on error
1160
1161      Most usual cause of error is a line with no or incorrect budget codes
1162      which woild cause order creation to abort
1163      If other correct lines exist these are processed and the erroneous line os logged
1164
1165 =head2 title_level_class
1166
1167       classmark = title_level_class(edi_item)
1168
1169       Trys to return a title level classmark from a quote message line
1170       Will return a dewey or lcc classmark if one exists according to the
1171       value in DefaultClassificationSource syspref
1172
1173       If unable to returns the shelfmark or classification from the GIR segment
1174
1175       If all else fails returns empty string
1176
1177 =head2 _create_bib_from_quote
1178
1179        marc_record_obj = _create_bib_from_quote(lineitem, quote)
1180
1181        Returns a MARC::Record object based on the  info in the quote's lineitem
1182
1183 =head2 _create_item_from_quote
1184
1185        item_hashref = _create_item_from_quote( lineitem, quote)
1186
1187        returns a hashref representing the item fields specified in the quote
1188
1189 =head2 _get_invoiced_price
1190
1191       _get_invoiced_price(line_object)
1192
1193       Returns the net price or an equivalent calculated from line cost / qty
1194
1195 =head2 _discounted_price
1196
1197       ecost = _discounted_price(discount, item_price)
1198
1199       utility subroutine to return a price calculated from the
1200       vendors discount and quoted price
1201
1202 =head2 _check_for_existing_bib
1203
1204      (biblionumber, biblioitemnumber) = _check_for_existing_bib(isbn_or_ean)
1205
1206      passed an isbn or ean attempts to locate a match bib
1207      On success returns biblionumber and biblioitemnumber
1208      On failure returns undefined/an empty list
1209
1210 =head2 _get_budget
1211
1212      b = _get_budget(schema_obj, budget_code)
