Dear Mr. Rao,
We have meticulously gone through your query and found that this transaction can't be treated as Stock Transfer since goods are being transfer to buyer who has raised the PO to your branch and in turn branch had raised the POs to your factory.
It would be treated as pre conceived sales. It would be termed a CST sale as the buyers are pre determined.
Following is the relevant judgment for your kind information.
