I have this table that should be adding up each column of the months, this is a dynamics pivot, which if the date is changing the months are rotating.
I will have a column that will be the balance of the client (this will change according to the client's debt), if what I want is to add the months until and stop until the months that have already reached the balance of the client.
see example in excel box, for more explanation.
Thanks

DECLARE @cols AS VARCHAR(MAX)
DECLARE @query AS VARCHAR(MAX)

;with mylist as (
  select DATEADD(month,-12, DATEADD(month, DATEDIFF(month,0,GETDATE()), 0) ) as [mnth]
  union all
  select DATEADD(month,1,[mnth])
  from mylist
  where [mnth] < DATEADD(month,-1, DATEADD(month, DATEDIFF(month,0,GETDATE()), 0) )
  )
select [mnth]
into #mylist
from mylist
order by [mnth] desc

SELECT @cols = STUFF((SELECT ',' + QUOTENAME(format([mnth],'MMM yyyy'))
        FROM #mylist
                     order by [mnth] desc
        FOR XML PATH(''), TYPE
        ).value('.', 'NVARCHAR(MAX)')
      ,1,1,'')

SET @query = 'SELECT CUSTNMBR, ' + @cols + ' FROM
      (
       select
         format([mnth],''MMM yyyy'') colname
        , b.CUSTNMBR
        , case a.SOPTYPE
                         when 3 then a.DOCAMNT
                         when 4 then a.DOCAMNT*-1
                         end Sales
       from #mylist
       cross join two..RM00101 b
       left join two..SOP30200 a on #mylist.mnth = DATEADD(month, DATEDIFF(month,0,a.DOCDATE), 0)
           and b.CUSTNMBR = a.CUSTNMBR

     ) sourcedata
      pivot
      (
       SUM([Sales])
       FOR [colname] IN (' + @cols + ')
      ) p '

--select @query -- use select to inspect the generated sql
execute(@query) -- once satisfied that sql is OK, use execute
