I'm having trouble adding the running total to my query. See attached for data. Here's where I'm at now but, it isn't working. Department represents a physician, FSC is primary insurance. Units represents the MTD total for the CPT for that provider/FSC/location.
selectt.YearMonth,
t.Department,
t.CPT,
t.FSC,
t.Location,
t.Units,
YTDUnits
from #T t
inner join (selectDepartment,
CPT,
FSC,
Location,
sum(Units) over(partition by Department, CPT, FSC, Location order by CPT) as YTDUnits
from #T
) t1
on t.Department=t1.Department
and t.CPT=t1.CPT
andt.FSC=t1.FSC
andt.Location=t1.Location
order by YearMonth,
FSC,
Location

Look at the windowing functions. I don't have anything readily available.

That's what I'm using in the sub query. Just noticed that I should be using the YTD stuff as the main query and left joining to the MTD stuff. Some months may not have a particular CPT code in the mix.

select t.YearMonth, t.Department, t.CPT, t.FSC, t.Location, t.Units, SUM (Units) OVER (ORDER BY CPT, yearMonth, Department, FSC) AS RunningTotal from #T t

Here's an example I shamelessly copied out of Itzik Ben-Gan's T-SQL Querying book:
SELECT custID, orderID, orderDate, val, SUM(val) OVER (PARTITION BY custid, YEAR(orderDate) ORDER BY orderDate RANGE UNBOUNDED PRECEDING) AS YTD_val FROM dbo.OrderValues;
and here's my attempt at an answer...
SELECT Yr , YearMonth , Units , SUM(Units) OVER (PARTITION BY Yr ORDER BY FOM ROWS UNBOUNDED PRECEDING) AS YTD_Total , SUM(Units) OVER (PARTITION BY YearMonth ORDER BY FOM ROWS UNBOUNDED PRECEDING) AS MTD_Total FROM ( SELECT CAST(LEFT(YearMonth,4) AS INT) AS Yr , DATEFROMPARTS (CAST(LEFT(YearMonth,4) AS INTEGER), CAST(RIGHT(YearMonth,2) AS INTEGER), 1) AS FOM , YearMonth , Department , CPT , FSC , [Location] , Units , Charges FROM #T ) x;

For a running total - you need to set the row boundaries in the windowing function so that row only calculates for the data from the beginning to the current row.
