EDI Error Handling and Exception Management 1 — Questions and Answers
Question 1: Which EDI transaction set is used to acknowledge the receipt and syntactic validity of an X12 interchange?
- 997 Functional Acknowledgment (Correct answer)
- 850 Purchase Order
- 856 Advance Ship Notice
- 810 Invoice
Correct answer: 997 Functional Acknowledgment
The 997 (or 999 in later versions) Functional Acknowledgment is the standard X12 transaction used to confirm receipt and report syntactic acceptance or rejection of a transmitted interchange.
Question 2: What AK501 value in a 997 Functional Acknowledgment indicates that a functional group was accepted with errors?
- E (Correct answer)
- A
- R
- P
Correct answer: E
AK501 value 'E' means the functional group is Accepted but Errors Were Noted, whereas 'A' means fully accepted and 'R' means rejected.
Question 3: In EDI error handling, what does a 'TA1 Interchange Acknowledgment' report on?
- Structural and envelope-level errors in the ISA/IEA segments (Correct answer)
- Business-logic errors in individual transactions
- Missing trading partner agreements
- Duplicate transaction set control numbers
Correct answer: Structural and envelope-level errors in the ISA/IEA segments
The TA1 segment is used to acknowledge the ISA/IEA interchange envelope and report structural errors at that level, before functional group processing occurs.
Question 4: Which error code in the AK304 element of a 997 indicates a required data element is missing?
- 1 (Correct answer)
- 2
- 3
- 5
Correct answer: 1
AK304 error code '1' signifies 'Mandatory Segment Missing,' while code '2' is 'Segment Not in Defined Transaction Set' and '5' is 'Too Many Segments.'
Question 5: When a trading partner sends a 997 with AK501 = 'R', what is the appropriate corrective action for the sender?
- Correct the identified errors and resend the functional group (Correct answer)
- Resend the identical interchange without changes
- Cancel the transaction and notify the partner by phone
- Wait 24 hours before attempting retransmission
Correct answer: Correct the identified errors and resend the functional group
An 'R' (Rejected) status means the functional group failed validation; the sender must fix the flagged errors in AK3/AK4 segments and transmit a corrected version.
Question 6: What distinguishes a syntactic error from a semantic error in EDI exception handling?
- Syntactic errors violate EDI structure rules; semantic errors involve incorrect business data values (Correct answer)
- Syntactic errors are caught by the receiver; semantic errors are caught by the sender
- Syntactic errors cause interchange rejection; semantic errors cause functional group rejection only
- There is no meaningful distinction between the two in modern EDI systems
Correct answer: Syntactic errors violate EDI structure rules; semantic errors involve incorrect business data values
Syntactic errors relate to malformed EDI structure (wrong segment order, invalid characters, missing envelopes), while semantic errors involve data that is structurally valid but logically incorrect for the business context.
Question 7: Which segment in an X12 999 Implementation Acknowledgment replaces the AK1 segment found in the 997?
- FA1 (Correct answer)
- IK1
- AK5
- CTX
Correct answer: FA1
The 999 Implementation Acknowledgment uses FA1 (Functional Acknowledgment Header) instead of the 997's AK1, and adds CTX segments for richer error context.
