Count a column group by two other column

Hi

I need to create a BIP report using BIP Desktop.

I have following xml

<?xml version="1.0" encoding="UTF-8"?><ListOfBipWorkareawiseTransaction

OrderEntrySales_QueryString="&apos;Order Entry - Orders&apos;.Search=&quot;[FieldName] = &apos;ABC&apos;&quot;"

><OrderEntry-Orders>
