End Lots

End lots are the points along the dependency chain where the chain no longer branches and where the vessels still contain quantities of bulk material. The View End Lots program (P31B61) enables you to track the downstream operations that use a specific consumable or additive item or that contains bulk material that was harvested from a specific block. The ability to track this information is critical, for example, when a supplier informs you that an item that was used in the blend process is flawed or contaminated. In this case, you want to be able to find any operation where the item was used so that you can deal with the affected lot.

You can also view end lots for selected operations from the Operation Trace/Track program. However, using this option, you can review the end lots for only one operation at a time.
