0.    INTRODUCTION

       This specification provides the definition of the Purchase
       order change request message (ORDCHG) to be used in Electronic
       Data Interchange (EDI) between trading partners involved in
       administration, commerce and transport.

1.    SCOPE

       the buyer's request to change a purchase order.

1.2   Field of Application

       The Purchase order change request message may be used for both
       national and international applications. It is based on
       universal practice related to administration, commerce and
       transport, and is not dependent on the type of business or
       industry.

1.3   Principles

       A buyer may request to change, or eventually cancel one or more
       goods items or services.
       
       A purchase order change request may refer to goods items or
       services related to one or more delivery schedules, call-offs,
       etc.
       
       A purchase order change request for cross-border transactions
       may contain additional information for customs and/or
       statistical purposes.
       
       A purchase order change request may contain details for
       transport and destination as well as delivery patterns.

3.    TERMS AND DEFINITIONS

3.1   Standard terms and definitions

       See UNTDID, Part 4, Chapter 2.6 UN/ECE UNSM - General Introduction,
       Section 2.

4.    MESSAGE DEFINITION

4.1   Data Segment Clarification

       This section should be read in conjunction with the Segment
       Table which indicate mandatory, conditional and repeating
       requirements.
       
       For guidance, the following principles serve to remove
       ambiguity in the application of an EDI Purchase Order Change.
       
       All specified dates/times should be in the format
       'yymmdd'/'hhmm' unless all parties involved in the transaction
       agree that there is a functional requirement for an alternative
       format. Periods should be specified as whole numbers
       representing the required period as indicated in the format
       qualifier (weeks, months, etc.).
       
       Where a choice of code or text is given only the code element
       should be used wherever possible.
       
       Conditional data that is not required in the message should not
       be included.
       
       Care must be taken that the segment qualifier in dependent
       segments do not conflict with the segment qualifier of the
       trigger segment of a group.
       
       Free text information within the message should be avoided as
       this inhibits automatic processing.

4.1.1  Header section

       Information to be provided in the Header section:

       The heading section of ORDCHG message contains the same
       segments in the same sequence as the ORDERS and ORDRSP
       messages. The actual use of these segments in the ORDCHG
       message is depending upon the value of the MESSAGE FUNCTION
       CODE (D/E 1225) of the BGM segment.

0010   UNH, Message header
       A service segment starting and uniquely identifying a message.
       The message type code for the Purchase order change request
       message is ORDCHG.
       
       Note: Purchase order change request messages conforming to this
       document must contain the following data in segment UNH,
       composite S009:

       Data element  0065 ORDCHG
                     0052 D
                     0054 97B

       Examples of the use of this DTM segment are: Lead times that
       apply to the whole of the order and, if no schedule is to be
       specified, the delivery date.
       
       The Date/time/period segment within other Segment group should

       specified within Segment group 47.
