One Storage Loc and One Warehouse

Hello Experts,

We have mapped one storage location to one warehouse.

So in this case how the system will restrict open stock from being picked ,Whose WT is not yet Confirmed.

Suppose i receive 10 pcs of mat A and WT is not yet confirmed,meanwhile request of 5pcs comes from production so how the system will restrict it ?

Here how we map availability group and Stock Types where we have one storage location and one warehouse number ?

Regards,
