Tracking split lumber lots and their source records

Dividing material creates a record event

When part of a lot goes to one project and the rest stays in stock, the original record should remain intact. Create child records for the portions and connect each to the parent. Record the quantity, unit, date and destination of the split. This keeps one source lot from appearing to remain fully available after part of it has left.

A split can happen without a sale: machining, sampling, damage segregation or moving stock into a different production stage may create separately managed portions. The important question is whether someone will need to identify that portion independently later.

Reconcile the quantities at the split

In a fictional example, a parent lot contains 120 pieces of one documented size and length. Seventy pieces move to Project A, 45 remain available and five are set aside for investigation. The record reconciles to 120 pieces. The five set aside should not disappear into a vague adjustment or remain counted as available stock.

That example works because the units and pieces are comparable. If material is cut into different lengths, piece count alone no longer preserves the quantity relationship. Retain dimensions or another appropriate quantity basis and document the processing event.

Carry evidence forward with its limits

A child lot can point to the parent's documents, but the record must show why those documents apply. If a parent record contains unresolved species or origin information, splitting it does not resolve the uncertainty. Likewise, one document covering only part of a shipment should not be attached indiscriminately to every child lot.

Keep operational traceability separate from certification accounting. A certification scheme may impose its own rules for claims, transfers and inventory controls. An internal parent-child table is not a substitute for those rules and does not authorize use of a certification claim.

If two lots are later combined, record that as a separate merge with both inputs identified. Do not rename the combined material as though it came from a single original lot. The quantity reconciliation guide helps preserve the arithmetic; the evidence record preserves what can legitimately be said about each portion.
