Formatting a Date if already using MIN function

[skifast]

I have a query where I am using the MIN function to filter out duplicate Call Numbers (Call_No). The query works well and returns 34 records -- perfect. Here it is:

SELECT RV_CALL_HISTORY.Call_No as "Call Number",
MIN(RV_CALL_HISTORY.Call_Log_Date) as "Call Log Date",
MIN(RV_CALL_HISTORY.Call_Hist_Date) as "Call Hist Date"
FROM RV_CALL_HISTORY
WHERE
RV_CALL_HISTORY.Call_Log_Date > '2012-04-01 00:00'
AND
RV_CALL_HISTORY.Call_Hist_Action_Officer='Joe Blow'
AND
RV_CALL_HISTORY.Call_Log_Date < GETDATE()
GROUP BY RV_CALL_HISTORY.Call_No

---------------------------
Now I would like to convert the Call_Hist_Date to:
YYYY.MM.DD

I have tried using the following, but then I lose the filter. I get 114 records:

SELECT RV_CALL_HISTORY.Call_No as "Call Number",
MIN(RV_CALL_HISTORY.Call_Log_Date) as "Call Log Date",
CONVERT(VARCHAR(10),RV_CALL_HISTORY.Call_Hist_Date,102) as [YYYY.MM.DD]
FROM RV_CALL_HISTORY
WHERE
RV_CALL_HISTORY.Call_Log_Date > '2012-04-01 00:00'
AND
RV_CALL_HISTORY.Call_Hist_Action_Officer='Joe Blow'
AND
RV_CALL_HISTORY.Call_Log_Date < GETDATE()
GROUP BY RV_CALL_HISTORY.Call_No,RV_CALL_HISTORY.Call_Hist_Date

-------------------------
Any idea how I can combine the MIN and CONVERT functions?
I am using Microsoft SQL Management Studio (Microsoft SQL Server 2008 R2)

Thanks,

Please use code tags when posting code.

Do the conversion around the min.
