All use cases

Trace a material lot through production.

Follow receipts, consumption and intermediate splits to identify recorded downstream batches and traceability gaps.

The recorded 40 kg issue leads to INT-203, which splits into B-203A and B-203B. B-203B's consumption has not been posted. I would retain both branches in the trace and flag the unresolved quantity on B-203B.

Follow the split into both batches
Follow the split into both batches. INT-203 from RM-203, B-203A, B-203B. Example records.INT-203from RM-203B-203AB-203B

You: Can we exclude B-203B because there is no posted consumption?

neil

No. The recorded split makes it a candidate downstream branch even though its transaction is incomplete. I would separate the relationship evidence from quantity reconciliation. Assigning a residual quantity without the actual transaction would make the diagram look complete while hiding the gap.

You: Write this up for review, with the sources and the follow-up work we need.

Here is the draft. I have kept the supported finding separate from the open questions, and prepared the evidence requests for the responsible roles.

RM-203 downstream trace and quantity exceptions

The issue to INT-203 and its split link both downstream batches to RM-203. B-203B's unposted consumption is a missing quantity, not evidence that the batch is unrelated. Carry that batch into the trace while requesting the transaction needed to reconcile consumption. Keep the genealogy question—where material went—separate from whether every quantity is accounted for.

Quality determines product impact and any market action. Recorded consumption identifies candidates; it does not itself establish a defect or authorise a recall.

Fictional source snapshots. No live query, assignment or approval.
