Storage
Sheet stock, remnants and picking: the material side of every order.
Stock that explains itself.
Every sheet that comes in or goes out leaves a line in the history.
Sheet stock is kept per material. The combined run draws the sheets it cuts by itself and books them with the reason Sammellauf; staff book goods receipts and count corrections by hand. Both paths run through the same booking, so no stock appears or disappears without a line saying who, why and for which internal order.
Stock can go below zero. That is deliberate: a negative figure is the honest message that the count no longer matches what was cut, not an error smoothed over in silence.
Remnants go back on the shelf.
A part-used sheet is not scrap.
What is left of a sheet after nesting goes back into stock as a remnant and is used again. In Alef Portal the same thing shows up in the price as a leftover-plate credit: the large rest goes back to stock and is not charged.
Picking lists.
Nobody creates a picking task. It arises from what is already there.
An internal order whose material is not staged yet is a picking task at the storage station. Gimel reconciles the tasks against the orders, so a task disappears when the sheets are staged and no list goes stale. The transport way from storage to the machine is part of what the plan weighs when it picks a station.
