Retrieve outgoing payment details for last 24 hours

Hi Everyone,

I made below query to get a list of outgoing payments over 100k for management monitoring purpose.  At the moment this retrieves data for the current date or for any date range.

However, I would like to modify this query to retrieve data for last 24 hours.

ex - from previous day 12 noon to current date 12 noon.

below is the query;

SELECT T0.DocNum AS 'DOC N0', T0.DocDate AS 'POST DATE', T0.DocTime AS 'TIME', T0.TransId AS 'TRANSACTION ID', T0.CardName AS 'VENDOR/CUSTOMER NAME',

T0.TrsfrSum AS 'AMOUNT', T0.TrsfrAcct AS 'TRANSFER A/C', T0.TrsfrRef AS 'REFERENCE', T0.Comments AS 'REMARKS', T1.U_NAME AS 'USER NAME' FROM dbo.OVPM T0

INNER JOIN dbo.OUSR T1 ON T1.USERID = T0.UserSign

WHERE DATEDIFF(DD, T0.DocDate , SYSDATETIME ()) > 0

AND DATEDIFF (DD, T0.DocDate, SYSDATETIME ()) < 2

AND T0.TrsfrSum > '100000'

GROUP BY T0.DocNum, T0.DocDate, T0.TransId, T0.CardName, T0.TrsfrAcct, T0.TrsfrRef, T0.Comments, T0.DocTime, T1.U_NAME, T0.TrsfrSum

ORDER BY T0.TrsfrSum desc, T0.DocDate desc, T0.DocTime desc

DocDate (DateTime)

DocTime (SmallInt)

Appreciate if you could explain to me how to modify the query to retrieve data for last 24 hours.

Thanks
