Dave thanks a lot for the reply..You are the best!!

I am doing the calculation using Running sum and the report is slicing and dicing between month,year and daily perfectly. I calculated the begining balance using previous(ending_bal) function. The ending is calculated using using Running sum. So things went right. thanks again..

The problem now is that the report is taking too much time to fetch data due to use of report level variables. As the data volume is around 80K to 100K.

Please suggest me something in this regard. Let me know if I am not clear in explaining my problem.

The challenge with elements like this is that the obvious choice of min() and max() don’t work, because the ending balance could – with the right set of transactions – be less than the starting balance. It’s for this reason that I would suggest calculating these values using a running sum function on the report instead.

Hi Dave
I have a measure object called begining and ending balance which i want to aggregate based on daily,month,quarter, and year. When I want to see monthly data and I remove the date dimension..It rolls up the individual records giving me the wrong result. For Example my daily transaction data is like..
User Date Year month BegBal EndBal
I1 11-May-2011 10PM 2011 5 0 100
I1 11-May-2011 11PM 2011 5 100 200
I1 11-May-2011 12PM 2011 5 200 250

This is correct when I see at lowest daily level data…But if I remove the date column..then i want month begining and ending balance which should be 0 and 250 respectively…however the report shows 300 and 550 that is it sums up..

Please help!!Thanks a lot in advance

Database delegated measures are designed for ratio calculations (either current year to prior year, or averages, or percentages, or…). Whether you use database delegated measures or local variables really depends on how quick your reports refresh.

Hi Dave, I have an object with a division formula and aggregate function sum. With a minimum aggregation level it work, but when replace with other superior level, the aggregate function sum work, as a normal work and the result needs to be a division.

I proposed to my user, use a database delegation, with all refresh that it need, or use a local variable in each report.

Do you know if exist a third option to this behavior?

Best Regards

It can also be used for sums – I had an example with a master-detail table layout, count distinct on master but if an item was included in query from the detail table then it counted all distinct rows ie at detail level even though the detail item was not included in the report. The query includes all rows as I believe this is standard Webi behaviour. As soon as the measure was database delegated the problem was resolved and the query only counted the distinct rows used in the report

Hi Dave
I have a question regarding percentages and averages. We have a view develoepd for all the calculations. when i include these objects in the universe should i just change the projection to database delegated with out having to define the object as
avg(column_name_from_view) in the object definition?
