One Delivery Can Create Several Traceability Paths
A delivery can arrive under one source identity and still leave Receiving with several different operational outcomes.
Traceability has to preserve those branches. Otherwise the business may retain the original lot number while losing what happened to different portions of the material.
One source does not guarantee one outcome
Consider 100 kg physically delivered under one Receiving Lot. Inspection and management decisions may determine that 70 kg can be released, 20 kg must be held and 10 kg rejected.
70 kg Released
Permitted to continue into available inventory.
20 kg Held
Preserved separately because a decision or condition remains unresolved.
10 kg Rejected
Recorded as rejected rather than disappearing from the delivery history.
The quantities still have to account for the 100 kg that physically arrived. But after disposition, their traceability paths are no longer identical.
Held material should not quietly become available stock
A shared supplier and lot identity does not erase the decision made about a particular quantity. Released, Held and Rejected are different operational states.
Preserving those states matters because a later investigation may need to establish not only where the material came from, but which part of it was permitted to continue and which part was not.
That is also why an observation and a management decision should remain separate pieces of evidence. The observation explains what was seen. The disposition records what was decided.
A traceability chain can branch without breaking
The objective is not to force one delivery into one neat history. It is to preserve the relationships when reality becomes less neat.
Good traceability keeps every outcome connected to the source.
That makes split outcomes explainable later without rewriting the original delivery as though only the accepted portion ever existed.
