Pivot Table - ungroup similar items

[AbrahamGluck]

I would like to ungroup similar items in the pivot table that is grouped by default, for example, I have in an invoice column on a worksheet 2 x the same invoice number (12345) the pivot table row will recognize it once, how can I change that and pivot table should list that twice?

Thanks In advanced
