Block stock or quality inspection

Hi,

We usually block the stock through MB1B 321/322 or 343/344 movements types. But we cant indicate warehouse number and storage type:

example: We have two units:

Material A

Batch: 1

Quantity 2

Storage type 010: 1 unit

Storage type 011: 1 unit

We need to block or put in quality control just 1 unit. We go to MIGO and we indicate:

Material: "A"

Bacth: 1

Quantity: 1

Movement type: 343.

But we can not indicate that we want to block just the unit on the 010 storage type or 011.

How can i do it? Through wich tcode?

Thanks in advance for the help.

Regards

Enzo
