Trace a lot in a recall

Click Trace back on a batch or Trace forward on a purchase. FourFoxes walks the chain and tells you if any records are missing.

A trace answers two questions in a recall: what went into this batch, and where did this lot end up.

Trace back from a batch

  1. Open the batch.
  2. Click Trace back.
  3. FourFoxes walks the chain: the batch, each ingredient lot in it, the purchase it came from, and the supplier.

Trace forward from a purchase

  1. Open the ingredient purchase (a supplier just called about a lot).
  2. Click Trace forward.
  3. FourFoxes shows every batch that used the lot, and for advanced inventory accounts, the packaged lots and shipments downstream, including the customer shipped to.

[facsimile candidate: recall trace page with completeness banner]

Read the banner first. A banner pinned to the top says whether the trace is complete or how many data gaps it found. Gaps are named in place: a batch with no linked ingredient purchases, a missing supplier lot number, an unrecorded customer, or a quantity that was not captured. A gap does not stop the trace; it tells you what you cannot prove.

You can export the exact trace you are looking at with Export PDF or Export CSV. The file is generated in the background and the download link lasts 24 hours.

Traces require the Member role or higher.

Practice before you need it

Run a trace on a recent batch this week. Every gap it reports is something you can fix now, while it is a chore instead of an emergency.
