Error: Cannot reserve 1,00 of item [item] because of stock shortage. Clear the Reservation required setting to allow further processing of the shipment.

Hi all,

I create an open sales order with one line (with one item number, quantity 1). Automatic reservation = yes. → system reserves a random serial number of the item number (10 pieces are physical available in the warehouse, so there is enough stock!)

I click on ‘Picking list’

I go to inventory & warehouse module and create a new shipment. I want to activate the picking so i could register the right serial number of the item number. But system gives the error: Cannot reserve 1,00 of item [item] because of stock shortage. Clear the Reservation required setting to allow further processing of the shipment.

Then i clear the Reservation required setting, but then system gives warning: Not all shipment lines could be reserved.

So it isn’t possible to register the right serial number in the picking route (because no picking route)

Very strange because few weeks ago it works with same settings (even without clearing the Reservation required setting…)

Have someone an idea why the system throws the error: Cannot reserve 1,00 of item [item] because of stock shortage. Clear the Reservation required setting to allow further processing of the shipment.

Thx!

Frederik
