Sales Order Quantities are not confirmed

Hi All,

When I create a sales order the quantities are not confirmed despite the availability of stocks.

Below are the CO09 Overview:

Avail Chk:02    Check.Rule:BO(Back order processing)

Totals display

Receipts:201380

Issues:80             Confirmed Issues:0

ATP Situation

Date               MRP element          MRP element data         Rec/reqd qty          Confirmed            ***.ATP qty

29.10.2014        stock                                                             201380                                              201380

Below are the settings in Availability check control(OVZ9)

Stocks: Safety stocks,stock in transfer and quality inspection stocks are selected

In/outward movements: All the check boxes are selected

Option A(check firmed planned orders only) selected for Incl.Planned order

Option X(take all production orders into account) selected for Incl.production order

Check without RLT is selected

In OVZ2 against 02, 'A' is assigned in both 'total sales' and 'total dlvreqs' columns and 'Block Qty Req' box is selected.

Please suggest which stops the confirmation.

Thanks in Advance
