Our inspection report adds a coupon when it sees the PLC completion state high after reconnect. The state belongs to the previous attempt. I have retained the trace and left the coupon under review. What should identify a result across reconnect without clearing the evidence or resending the job?
Give the job attempt an identity that survives that interruption, with an agreed meaning for receipt and completion. The receiving application can then recognise a result it already processed. For the existing coupon, can your retained evidence connect that high state to one identified attempt?
