Warehouse pick lot validation

Specification compliance is enforced during warehouse pick operations at four points: pick creation, auto-allocation, manual lot entry, and pick registration.

Pick creation

Pick creation is never blocked. If pre-assigned lots are non-compliant, a warning is displayed and the pick is created for the supervisor to resolve during picking.

Auto-allocation

The auto-allocation engine (FEFO) skips non-compliant lots. If all available lots are non-compliant, the pick line is created with a blank lot number for manual assignment.

Manual lot entry

Compliance Action	User Type	Behavior
Show Error	Standard user	Error shown. Lot cleared. You must choose a compliant lot.
Show Error	Authorized user	Confirmation dialog. Override reason required. Override logged with the Stage field value updated as Picking.
Show Warning	Any user	Warning shown. Lot accepted.

Previously overridden lots pass silently on re-entry if the profile has not changed.

Pick registration

All lots are re-validated at registration to detect profile or attribute changes since pick creation.

Scenario	Behavior
Lot passes all criteria	Proceeds silently. The lot is registered on the warehouse pick without any user prompts or validation messages.
Lot fails — Show Error, standard user	Registration blocked. Error shown.
Lot fails — Show Error, authorized user	Confirmation dialog. Override reason required. Override logged.
Lot fails — Show Warning	Warning shown. Registration allowed.
Previously overridden, profile unchanged	Passes silently.
Previously overridden, profile changed	Re-validation triggered. New override required.
