Order not allow to cancel after Warehouse Picking Confirmation.

I have one Sales order , I have used Warehouse Picking confirmation process .

And order stock has transferred from Storage location to Staging Location. Currently order stock is available at Staging Location and status is 550 .

But we need to implement process , where we need to cancel the order at this stage and respective stock need to transfer from Staging Location to TEMP location by Manual Inventory Replenishment.

But currently

>i am not able to cancel the order as Cancel order option is disable in Order Detail screen and >hence Stock also shows committed at Staging location Qty and

>hence not able to perform stock transfer as no available Qty
