Exceptions to the on-hand Qty deducted MRP suggestions

Hello everyone,
I am preparing for MRP operation. MRP will suggest the quantity minus On-hand Qty.
I have two questions about this.

  1. Even with on-hand Qty, there are a few parts that need to be purchased as much as the demand amount. Of course, if you don’t check Generate PO Suggestions in the part, the PO will not appear, but I want the PO to appear.
    Is it possible to set not to deduct on-hand Qty for each part?

  2. We have Warehouse/Bin which is physically very far away. So the warehouse/bin’s On-Hand should not be deducted from the MRP as it cannot actually be utilized.
    There is also a defective bin. These should not be deducted either. Can some bins be set not to be deducted from the MRP?

Thank you in advance.
