✍️ Sample EDI Questions & Answers
1. In EDI testing, what does 'UAT' stand for and why is it important?
UAT involves business stakeholders validating that the EDI-produced data (orders, invoices, shipments) correctly reflects real-world business scenarios and requirements.
2. Which type of EDI testing verifies that the business data in a transaction (prices, quantities, dates) is correct?
Semantic or content validation checks whether the values within a valid EDI document make business sense, such as valid item numbers, acceptable quantity ranges, and correct date formats.
3. Which EDI component is responsible for converting internal data formats into EDI formats and vice versa?
The EDI Translator is a key component responsible for converting data between a company's internal application format and the standardized EDI format. For outbound documents, it translates data from an ERP system into an EDI message; for inbound documents, it converts the EDI message back into a format the internal system can understand. This ensures seamless data exchange between disparate systems.
4. Which segment in an X12 EDI transaction set indicates the end of the transaction and contains a count of included segments?
The SE (Transaction Set Trailer) segment marks the end of an individual transaction set and contains the segment count, which validators use to check document completeness.
5. In X12 EDI, what is a 'segment'?
A segment is a named, ordered collection of related data elements that form a logical unit, like the N1 name segment.
6. In X12 EDI, what does the qualifier 'ZZ' in ISA07 typically indicate?
ZZ is the 'Mutually Defined' qualifier, meaning the trading partners have agreed on the format and value of the accompanying identifier without using a standard code.
