Question

i’ve a problem with a SSRS report and query in Sql Server 2008 that, in my opinion, is (easy) solvable in excel … but, not in Sql !
Follow what i need:

My table:

Start amount X: 1.000.000

      Month    Value               AmountX
      1        1 000         (AmountX - Value)       = 999 000
      2          500         (Prev. AmountX - Value) = 998 500
      3          800         (Prev. AmountX - Value) = 997 700 
      .....
      .....

Check out RunningValue(), you would use this as a function in your SSRS report

=RunningValue(Fields!Value.Value, Sum, Nothing)
