SAP HANA query to show PO's with the same total amount

Experts,

What syntax do I need to use to show PO's with the same total amounts.

SELECT T0."DocNum", T0."DocDate", T0."DocDueDate", T0."CardName", T0."DocTotal" FROM OPOR T0 WHERE T0."DocTotal" =  T0."DocTotal"

This one brings back all the PO's.

Thanks,

Marli
