Aggregate Functions for TempTable - tsql

Question

Scenario:
I use tempTable (# temporary table) in SQL Server 2008 R2 in a stored procedure, and I need to use aggregate functions such as MIN(), MAX() and ... to perform a series of calculations on the temp table's columns.
But, temp table doesn't have any aggregate functions. Now what's the best solution for this problem ?
Thanks
Update:
I want to obtain Minimum Remain of customer's Bank Account in today Transactions
CREATE TABLE #TempTableToday
(
DetailAccountId BIGINT,
RemainToday BIGINT,
Profit DECIMAL(18, 6),
LastDate DATETIME
);
CREATE TABLE #TempTableMinRemainToday
(
DetailAccount2Id BIGINT,
MinRemainToday DECIMAL(18, 2)
);

Please try this. I am still a bit unclear on the functionality but my best guess is that you are having the MIN() inside the loop so its only returning one value. I have moved it outside the loop so best case is that it will retrieve the MIN() of a set. You will have to modify this query a bit to merge with your query.
IF OBJECT_ID(N'tempdb..#AccountingDocsDetail') > 0
DROP TABLE #AccountingDocsDetail
IF OBJECT_ID(N'tempdb..#TempTableToday') > 0
DROP TABLE #TempTableToday
IF OBJECT_ID(N'tempdb..#TempTableMinRemainToday') > 0
DROP TABLE #TempTableMinRemainToday
