Sales Order to Work Order not working

For some items I have multiple uom.
I have created a UOM called Batch which means 1 Batch = 1000 Nos
In sales order i have used the another UOM named Batch created along with that item.

After that i try to create a work order in which the total quantity is shown correctly.

After creating a work order to an item it is showing only the quantity to manufacture of 30 .

If I go back to sales order and again I try to create a work order again only a quantity of 30 is reduced against that item in the popup.


How can I solve this?
