EDI EDI Testing and Validation 2 — Questions and Answers
Question 1: What is the purpose of a control number in EDI transactions?
- To uniquely identify each transaction and enable matching of acknowledgments and detecting duplicates (Correct answer)
- To specify the EDI version number
- To encrypt the transaction payload
- To identify the VAN routing path
Correct answer: To uniquely identify each transaction and enable matching of acknowledgments and detecting duplicates
Control numbers at the ISA, GS, and ST levels uniquely identify each interchange, functional group, and transaction set, enabling acknowledgment matching and duplicate detection.
Question 2: In EDI validation, what is a 'mandatory element' error?
- A required data element designated as 'M' in the EDI standard is missing or empty (Correct answer)
- An optional field contains an unexpected value
- A numeric field contains alphabetic characters
- The document exceeds maximum allowed file size
Correct answer: A required data element designated as 'M' in the EDI standard is missing or empty
When an element marked as mandatory (M) in the X12 standard or implementation guide is absent, it generates a mandatory element error that will typically cause the 997 to report an error.
Question 3: What is an EDI implementation guide (IG)?
- A trading partner-specific document that specifies which elements, codes, and rules apply to their EDI transaction sets (Correct answer)
- The official ANSI X12 standard publication
- A software installation manual for EDI translators
- A VAN provider's network topology diagram
Correct answer: A trading partner-specific document that specifies which elements, codes, and rules apply to their EDI transaction sets
An implementation guide customizes the base EDI standard for a specific trading partner, defining which elements are required, optional, or not used, along with valid code values.
Question 4: During EDI testing, a supplier receives a 997 with AK5*R. What does this indicate?
- The transaction set was rejected due to errors (Correct answer)
- The transaction set was accepted without issues
- The functional group was accepted with errors
- The interchange was received but not yet processed
Correct answer: The transaction set was rejected due to errors
AK5*R in a 997 Functional Acknowledgment means the transaction set was Rejected, and the preceding AK3/AK4 segments will describe the specific errors found.
Question 5: What is parallel testing in an EDI go-live strategy?
- Running EDI transactions alongside manual processes simultaneously to verify EDI output matches expected results (Correct answer)
- Testing two EDI maps in parallel to choose the best one
- Sending duplicate EDI transmissions to two VANs simultaneously
- Running EDI tests on a staging server while production is live
Correct answer: Running EDI transactions alongside manual processes simultaneously to verify EDI output matches expected results
Parallel testing runs the new EDI process side-by-side with the existing manual or legacy process, comparing outputs to validate accuracy before cutting over fully to EDI.
Question 6: What is a common cause of EDI 'trading partner not found' errors in production?
- Mismatch between the ISA sender/receiver IDs in the document and the configured trading partner profile (Correct answer)
- Network latency on the VAN connection
- Incorrect date format in the ISA08 field
- Using the wrong EDI version number
Correct answer: Mismatch between the ISA sender/receiver IDs in the document and the configured trading partner profile
When the ISA02/ISA04 qualifier-ID pairs in a received document don't match any configured trading partner profile, the EDI system cannot identify the sender or intended recipient.
