Hi
I am assuming that Dinamica Tabs are Pivot Tables in the UK/US versions of
Excel.
If that is the case, then highlight any Date value on the table>right
click>Group and Show Detail>Group>Months>OK
Note that all items within the Date filed must be true Excel dates and not
text representations of dates, and there must be no blank cells within the
range, otherwise Excel will display a message saying it Cannot Group by that
item.
