ASCP planned order demand is not calculated

I have run the plan 'Plan1' for item 'A' 100 qty, which is already having a pending batch 'batch1' of 100 qty.
batch is having ingredient ING1 of 50 qty
So In planning workbench I got

Item Order_type qty Order_no
A forecast 100 none
A Work order 100 Batch1
Ing1 Work order demand 50 Batch1
Ing1 Planned Order 50 PO1

Now I have cancelled batch 'Batch1'
and run same plan
It will generate Planned order of 100, But no ingredient demand is calculated

Item Order_type qty Order_no
A forecast 100 none
A Planned Order 100 XXX

Can you tell me why this is happening ? is any setup missing ?

Thanks
