0.    INTRODUCTION

       This specification provides the definition of the Request for
       document message (REQDOC) to be used in Electronic Data
       Interchange (EDI) between trading partners involved in
       administration, commerce and transport.

1.    SCOPE

1.1   Functional Definition

       A message to enable a party request the sending, or re-sending,
       of data, either as a document or message, or in some other
       agreed form.

1.2   Field of Application

       The Request for document 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

       The message is used to request a document to be sent, either
       electronically or otherwise. Its use should be limited to
       requesting documents, for which there is no other more specific
       message already provided (e.g. Request for Quotation).
       
       Parties can request documents on their own behalf, or on behalf
       of third parties.
       
       The message can be used to request individual documents by
       identity, or by specifying product and/or other related data to
       retrieve all relevant documents.
       
       Typical uses of the Request for Document Message are to request
       information from a data base (e.g. requesting a copy of a test
       certificate), requesting catalogue data, and requesting
       statements of account.

                     0054 97B
                     0051 UN

       process this segment manually.

       their dates, relating to the whole message.

          specified e.g. the sender and receiver of the report are
          known to each other, thus only the coded ID is required, but
          when a new address might have to be clearly specified, e.g.
