Hi Pramod,
In BBP_PD deleted line will be marked red color.
You must check in Adobe form, where you print the PO lines. There will be some kind of table with loop statement. In this loop find 'where' clausule and check if there is <po_item>-DEL_IND ne 'X'. statement.
I've checked standard Adobe form and there is no where condition.
Try to add it and re-test.
Regards,
Marcin
