SQL查询的SUM子集

我有一个关于在SQL Server 2008 R2中的现有查询上创建运行总数的问题。SQL查询的SUM子集

基本上，我有从3个独立的表和组将它们组合的数据以产生用于的ACCOUNT，PROFITCENTRE，TIMEID和DIVISION

每个组合中的单个条目。然而的查询时，我需要改变在SIGNEDDATA值，每个条目都是前几个月的总和。

例如

TIMEID 20120300（2012年3月）将包含-35143.0000000000
TIMEID 20120400（2012年4月），则应当包含-36000.0000000000（三月加上-857四月）
TIMEID 20120500（2012年5月）应-36857.0000000000等，

而不是我目前得到的，这是SIGNEDDATA每个月的总和，通过ACCOUNT, PROFITCENTRE, DIVISION分组等，但不添加到先前的蒙HS。

我该如何做，因为我试图从GROUP BY子句中删除TIMEID，但我只是得到了不能检索列的常见错误，因为它不包含在聚合或Group by中。 ....？

我的选择如下：

Insert INTO Data_Services.dbo.[NEW_TABLE] 
Select 
[Account], 
[Category], 
[DataSrc], 
[ProfitCentre], 
'MY_FLOW' as [Flow],

sum(round([SignedData],2,0)) as SignedData, 
[Division], 
@CurrentTime as CTimeID
