Use the Viewer role to answer a stock or traceability question from the recorded facts. Begin with the exact piece reference, material code, batch or job reference supplied by the person asking. Keep the physical question separate from what the register currently says.
Find the right evidence
Find a piece explains the current demand, required guaranteed length, ranking and rejected candidates. Searching holds nothing. You can inspect a result, but reserving needs an Operator or Supervisor role. Check all allowances and accepted conditions before interpreting why one piece appears ahead of another.
Piece history links a piece to its operations, labels and any parent or child. Distinguish a piece waiting for put-away from one confirmed in a bin, and a reservation from a checkout. The state records a particular point in the workflow; it is not a fresh physical inspection by the reader.
Explain the record accurately
A measured length and a guaranteed length answer different questions. Guaranteed length allows for the recorded uncertainty. A job can need extra length for processing allowance, saw kerf, trim and buffer. A measured piece that appears long enough may therefore be ineligible.
Read the reason given for a rejection or hold. Where there was a correction, inspect the later event and the current label generation rather than copying an earlier measurement. A child remaining after a cut has its own identity. Trace back through the lineage when the question concerns where it came from.
Pass on an actionable enquiry
Reports help supervisory review, but your role does not correct a measurement, release a reservation or settle a held cut. Give the supervisor the exact piece reference, relevant event and visible reason. If the issue concerns policy meaning, include the searched demand and the rule explanation for the author and reviewer.
Use Read history and state and Understand exact lengths when describing findings. Report the scope of the evidence you read so that somebody else can reproduce the enquiry.
