## Some guidance needed....

 Author Message Paul Morris-1011726 Old Hand Group: General Forum Members Points: 327 Visits: 336 I am wondering how I should go about handling weighted by month calculations for a trending report. Currently, I just use (total/ * 12 to get the trending number.Info:I work at a law firm where all the attorneys have a target number for the year. Based on historical numbers by month, each month is weighted (the tendency is that they close more towards the end of the year so it is weighted heavier). As a stop gap (due to time limitations), I am going to use static numbers until I can create something to calculate the weight 'on the fly'.So my questions is, should I do the calculations in the expresion on report or with T-SQL in SELECT statement? How should I handle cumulative weighted total? These are the static percent numbers by month:(0.04, 0.06, 0.09, 0.08, 0.09, 0.08, 0.09, 0.09, 0.08, 0.09, 0.08, 0.13) Sean Lange SSC Guru Group: General Forum Members Points: 63646 Visits: 17967 It seems like maybe this should be in a query instead of the report. Then you don't need any sort of stop gap due to time limitations. Create a table for MonthWeights and do it right. It will probably take less time than some hard coded messy case expression anyway.`create table MonthWeights( MonthNum int primary key, WeightMultiplier numeric(5,2))insert MonthWeightsselect 1, 0.04 union allselect 2, 0.06 union allselect 3, 0.09 union allselect 4, 0.08 union allselect 5, 0.09 union allselect 6, 0.08 union allselect 7, 0.09 union allselect 8, 0.09 union allselect 9, 0.08 union allselect 10, 0.09 union allselect 11, 0.08 union allselect 12, 0.13`Now just join to it and use the value in your calculation. _______________________________________________________________Need help?

I was thinking along those lines too just wasn't sure if that was the best method. When I create the 'on the fly' calculation, I can just use that table....Thanks again, have a good day!
