Inventory journal and blocked items

Hi everyone,
When using the Phys.Inventory journal and trying Functions->Calculate Inventory, I get the following error message:

Blocked must be No in Item No.='DR00145'.

This item is indeed blocked, same thing for another 8 items.
What shall I do to be able to calculate the inventory?
Thanks in advance :)

You should Unblock them or set filter on Blocked No. while running the Calculate Inventory
