HL7 v2 acknowledgement utility
HL7 ACK Generator & Analyzer
Generate practical HL7 acknowledgement messages or inspect an existing ACK for MSA result, ERR details, message-control-ID matching, routing reversal, and acknowledgement-mode fields.

Create or inspect an acknowledgement
This is a practical integration debugging aid, not a certified HL7 conformance validator. It reads field and encoding delimiters from MSH where possible.
The generated MSA-2 value comes from the original MSH-10 control ID.

Supported in this version
Practical HL7 acknowledgement workflows
Generation
AA, AE, AR, CA, CE, and CR results; sender/receiver reversal; MSH-10 to MSA-2 correlation; optional MSA text; and ERR location, severity, diagnostic, and user-message fields.
Analysis
MSA result interpretation, original control-ID comparison, MSH-15/MSH-16 request interpretation, sender/receiver checks, version and trigger checks, and multiple ERR segments.
ERR locations
Reads modern ERR-2 locations and falls back to legacy ERR-1 location data, displaying segment, occurrence, field, repetition, component, and subcomponent positions.
Deliberate limits
It does not apply a site-specific HL7 profile, validate every version-dependent field rule, send messages, or prove that an application processed a message correctly.
FAQ
HL7 ACK questions
What do AA, AE, and AR mean?
AA indicates application acceptance, AE indicates an application error, and AR indicates application rejection. The analyzer also recognises the commit acknowledgement codes CA, CE, and CR.
Why compare MSA-2 with MSH-10?
MSA-2 identifies the message control ID being acknowledged. Supplying the original message lets the tool show whether it matches the original MSH-10 value.
What are MSH-15 and MSH-16?
They indicate when accept and application acknowledgements are requested. The analyzer translates common AL, NE, ER, and SU values when the original message is supplied.
Does the generator create the exact ACK required by every interface?
No. Local profiles can impose additional segments, fields, message structures, code systems, or acknowledgement rules. Treat the output as a practical starting point for development and testing.
Can I paste production messages?
No. Use synthetic or properly de-identified test messages only.
