    I want to get the sum and I want to get the sum of only last month for VenNum by FiYr and DocDte.  I am having trouble adding the sum of only the previous month.

    Select count(*) as cnt, T1.FiYr, T1.DocDte, T1.VenNum,  
    Sum(T1.DocCurrAmt) as DocCurrAmt
    From PH.[dbo].[PHTbl] T1
    Where DocTypeDesc Like '%Scan Base%' and T1.VenNum = '1234'  ANd T1.FiYr = '2023' and T1.DocDte = '2023-02-20'
    Group by T1.FiYr, T1.DocDte, T1.VenNum 
    Order by FiYr, T1.DocDte

    Without sample data and DDL it's not easy to provide working code.

    But in pseudo-code, something like this

    select sum(iif(date in last month), value, 0)

    The absence of evidence is not evidence of absence

    The absence of consumable DDL, sample data and desired results is, however, evidence of the absence of my response

    Maybe?:

    Select count(*) as cnt, T1.FiYr, T1.DocDte, T1.VenNum,  
    Sum(T1.DocCurrAmt) as DocCurrAmt, Max(T2.DocMonthlySum) AS MonthlySum
    From dbo.table_name T1
    cross apply (
        Select sum(T2.DocCurrAmt) as DocMonthlySum
        From dbo.table_name T2
        Where T2.FiYr = T1.FiYr AND T2.VenNum  = T1.VenNum AND 
            T2.DocDte >= DATEADD(MONTH, DATEDIFF(MONTH, 0, '2023-02-20'), 0) AND T2.DocDte < DATEADD(MONTH, DATEDIFF(MONTH, 0, '2023-02-20') + 1, 0)
    ) as T2
    Where DocTypeDesc Like '%Scan Base%' And T1.VenNum = 1234 And T1.FiYr = '2023' And T1.DocDte = '2023-02-20'
    Group by T1.FiYr, T1.DocDte, T1.VenNum 
    Order by FiYr, T1.DocDte
