Insights

These five show up in Harbor Engine’s error queue more than almost anything else in Penford training traffic. None of them need heroics — they need the right fix in the right layer.

1. Empty MSH-10 (ACK AR)

Symptom: MSA-1 = AR; ERR often Table 0357 101 or a clear “control ID” reject.

Fix: Give the message a unique control ID; make the sender generate one forever. One-off repair: Edit & resend with an audit reason.

Refs: ACK AR, MSH, error 101.

2. DOB in human formats

Symptom: AE on PID-7; “not a valid TS/DTM.”

Fix: Transformer date → YYYYMMDD. Never invent a DOB.

Refs: PID-7 insights in the viewer, PID reference.

3. Missing MRN (PID-3)

Symptom: Lab NAKs; bed board may still AA.

Fix: Ask registration. Do not copy the account (AN) into an MR-typed field.

Refs: error 101, PID.

4. Wrong processing ID (MSH-11)

Symptom: AR / Table 0357 202.

Fix: Point PROD at PROD. Do not rewrite MSH-11 to sneak traffic into TEST.

Refs: error 202, ACK AR.

5. Code not in the receiving table (PID-8, OBX-3, …)

Symptom: AE / Table 0357 103.

Fix: Code-table lookup with a * default; or add the code with governance — do not silently coerce clinical meaning.

Refs: error 103, OBX.
