Reporting Methods

Framework EDI (FREDI) reports errors in ASC/X12 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.
Functional Acknowledgment. ASC/X12 standard mechanism by which a receiver of an EDI document can report back syntactical errors discovered in functional groups back to the sender. The receiver prepares an EDI document implementing the Functional Acknowledgment Transaction Set (997), reports those errors in the EDI document and sends that document back to the sender.
Interchange Acknowledgment. ASC/X12 standard mechanism by which a receiver of an EDI document can report back syntactical errors discovered in the interchange control structure back to the sender. The EDI document sent back to the sender records the errors in the Interchange Acknowledgment Data Segment (TA1).
Implementation Acknowledgment. ASC/X12 standard mechanism by which a receiver of an EDI document can report back syntactical and situational errors discovered in functional groups back to the sender. The EDI document sent back to the sender implements the Implementation Acknowledgment Transaction Set (999).

Auto-Create Control Headers

Each acknowledgment has its own defined structure containing data segments only applicable to them, but, being EDI documents they conform to a standard structure, that is, they all must have the following control headers, which are automatically created by FREDI:

Interchange Control Header (ISA)
Interchange Control Trailer (IEA)
Functional Group Header (GS)
Functional Group Trailer (GE)

Auto-Create of Interchange Control Header (ISA)

For documents, the acknowledgment is always wrapped in an interchange envelope consisting of the Interchange Header (ISA) and the Interchange Trailer (IEA) control segments. The Interchange Header (ISA) is constructed as follows:

POSITION	ELEMENT ID	DESCRIPTION	CONSTRUCT INFO
01	I01	Authorization Information Qualifier	Assigned default value of "00" (for No Authorization Information Present)
02	I02	Authorization Information	No default value is assigned, but because the presence of this data element is mandatory a string of space characters as long as the minimum length requirement will be used as value to this data element if no other value is assigned.
03	I03	Security Information Qualifier	Assigned default value of "00" (for No Security Information Present)
04	I04	Security Information	No default value is assigned, but because the presence of this data element is mandatory a string of space characters as long as the minimum length requirement will be used as value to this data element if no other value is assigned.
05	I05	Interchange ID Qualifier	The receiver interchange ID qualifier from the subject interchange is assigned to this data element.
06	I06	Interchange Sender	The interchange receiver of the subject interchange is assigned to this data element.
07	I05	Interchange ID Qualifier	The sender interchange ID qualifier from the subject interchange is assigned to this data element.
08	I07	Interchange Receiver	The interchange sender of the subject interchange is assigned to this data element.
09	I08	Interchange Date	Defaults to current date in GMT when this header is created. The date is in GMT.
10	I09	Interchange Time	Default to current time in GMT when this header is created. The time is in GMT.
11	I10	Interchange Control Standards	Assigned default value of "U" (for ASC X12, TDCC, UCS)
	I65	Repetition Separator	The repetition separator in the subject interchange is used as the repetition separator of the acknowledgment's repetition separator. The value is assigned to this data element.
12	I11	Interchange Control Version Number	The version is taken from the version information specified in the schema. The combined string length of the version and the release is truncated so that it does not exceed the maximum length requirement of the data element.
13	I12	Interchange Control Number	The control number is the incremental count of interchanges within the document, padded to the left with zeros to satisfy the minimum length requirement. The first interchange has a control number of 1. The value here is saved to be later stored in the Interchange Trailer's (IEA) data element I12 when the interchange is closed.
14	I13	Acknowledgment Requested	Assigned default value of "0" (for No Acknowledgment Requested).
15	I14	Interchange Usage Indicator	Assigned default value of "T" (for Test).
16	I15	Component Element Separator	The component element separator from the subject interchange is also used for the acknowledgment's component element separator. The value is assigned to this data element.

Auto-Create of Interchange Control Trailer (IEA)

The Interchange Trailer (IEA) is constructed as follows:

POSITION	ELEMENT ID	DESCRIPTION	CONSTRUCT INFO
01	I16	Number of Included Functional Groups	The total count of functional groups created since the creation of the interchange header is assigned to this data element.
02	I12	Interchange Control Number	The control number that was assigned to the Interchange Control Header (ISA) is also assigned here.

Auto-Create of Functional Group Header (GS)

After the interchange header, the functional group envelope is the next layer created consisting of the Functional Group Header (GS) and Trailer (GE) control segments. The Functional Group Header (GS) is constructed as follows:

POSITION	ELEMENT ID	DESCRIPTION	CONSTRUCT INFO
01	479	Functional Identifier Code	Defaults to "FA".
02	142	Application Sender's Code	Assigned to the sender's Application Receiver's Code from the subject document.
03	124	Application Receiver's Code	Assigned to the sender's Application Sender's Code from the subject document.
04	373	Date	Defaults to current date in GMT when this header is created.
05	337	Time	Default to current time in GMT when this header is created.
06	28	Group Control Number	The control number is the incremental count of functional group within the interchange, padded to the left with zeros to satisfy the minimum length requirement. The first functional group has a control number of 1. The value here is saved to be later stored in the Functional Group Trailer (GE) data element 28 when the functional group is closed.
07	455	Responsible Agency Code	The controlling agency code "X" is assigned for ASC/X12.
08	480	Version / Release / Industry Identifier Code	The version, release, sub-release and industry from the schema (that has been selected to use as guideline for creating objects in the functional group) is stored in this data element.

Auto-Create of Functional Group Trailer (GE)

The Functional Group Trailer (GE) is constructed as follows:

POSITION	ELEMENT ID	DESCRIPTION	CONSTRUCT INFO
01	97	Number of Transaction Sets Included	The total count of transaction sets since the creation of the functional group header is assigned to this data element.
02	28	Group Control Number	The control number that was assigned to the Functional Group Header (GS) is also assigned here.
