Reporting Syntactical Errors for UN/EDIFACT

Framework EDI (FREDI) reports errors in UN/EDIFACT documents using the following methods:

Event Notification. When EDI documents are loaded or created, errors discovered in these processes are passed back to the client application in real-time through events. The errors reported here are all errors encountered by FREDI operation errors, system errors, syntax errors, situational errors, etc.
Syntax and Service Report Message for Batch EDI. EDIFACT reports errors for EDI documents using the CONTRL implementation guideline, which reports acknowledgment in at most 2 CONTROL messages per subject interchange.
1. Interchange Receipt. Acknowledgment for receipt of interchange.
2. Interchange Response. Acknowledgment of action taken as a result of syntactical check.
Note: A CONTRL message reports for one subject interchange only.
Below is an actual document showing 2 CONTRL messages created for a single subject interchange. The first message is the interchange receipt, and the second message is the interchange response.

Auto-Create of Interchange envelope for CONTRL message

The CONTRL message generated for batch EDI is wrapped in the interchange envelope before it is sent back to the sender of the subject interchange. The interchange header (UNB) service segment is constructed by FREDI as follows:

POSITION ELEMENT ID DESCRIPTION CONSTRUCT INFO

010 S001 SYNTAX IDENTIFIER The component elements in this composite is set to the same value as the data elements in the subject interchange.

020 S002 INTERCHANGE SENDER The component elements in this composite is set to the same value as the interchange recipient S003 composite of the subject interchange.

030 S003 INTERCHANGE RECIPIENT The component elements in this composite is set to the same value as the interchange sender S002 composite of the subject interchange.

040 S004 DATE AND TIME OF PREPARATION The date and time values in this composite element is set to the current date and time. By default, the date and time is in GMT.

050 0020 INTERCHANGE CONTROL REFERENCE The default value of this control number is the incremental count of interchange envelopes in the entire EDI document. The number is padded with zeros to satisfy minimum length requirement.

110 0035 TEST INDICATOR The test indicator value is the same as that of the subject interchange.

All other data elements not specified in the table above are not assigned a value, and are regarded as empty. The client should programmatically assign the appropriate value where applicable. See Procedure for Changing a Value in a UN/EDIFACT Document.

The interchange trailer (UNZ) service segment is constructed as follows:

POSITION	ELEMENT ID	DESCRIPTION	CONSTRUCT INFO
010	0036	INTERCHANGE CONTROL COUNT	A numeric value is assigned to this data element for the number of CONTRL messages created and enveloped by the interchange. The value '1' is assigned if an interchange receipt, or an interchange response, only is created. The value '2' is assigned if an interchange receipt and a interchange response are both created.
020	0020	INTERCHANGE CONTROL REFERENCE	The value of this data element is the same as the interchange control reference set in the interchange header.

Auto-Create of Message envelope of the CONTRL message

The Message Header (UNH) for the CONTRL message is constructed as follows:

POSITION	ELEMENT ID	DESCRIPTION	CONSTRUCT INFO
010	0062	Message Reference Number	The value set here is the incremental count of messages created in the interchange. The value is padded with zeros to satisfy minimum length requirement.
020	S009/0065	Message Type	The message type identifier "CONTRL" is assigned to this component element.
	S009/0052	Message Version Number	Version number from Schema. Example, "S" or "D".
	S009/0054	Message Release Number	Version release from Schema. Example, "93A".
	S009/0051	Controlling Agency	Controlling agency is "UN".
	S009/0057	Association Assigned Code	Industry from Schema.

The Message Trailer (UNT) for the CONTRL message is constructed as follows:

POSITION	ELEMENT ID	DESCRIPTION	CONSTRUCT INFO
010	0074	NUMBER OF SEGMENTS IN A MESSAGE	The number of data segments created in the message is assigned to this data element.
020	0062	MESSAGE REFERENCE NUMBER	The value set here is identical to the same data element type in the message header.
