How to omit a blocked bin from issuing materials to a reservation

Hi All

Is there some standard config that will allow me to 'hide' the stock held in a warehouse bin when I process and MB1A movement type 281.

Problem:

After processing the MB1A I look into LB10 and try to process the pick but the stock is 'unavailable for picking' and I then have to reverse the material document to cancel the pick.

Although the bin is blocked for 'stock removal' can I also hide it from the MB1A process so that SAP omits all blocked bins from picking.

I hope I have explained myself adaquately.

Thanks in advance

Darren
