Calculating Life to date values

Question

Hi there,
the users are looking to get life to data values for service order. We can do this in the query (on the front end) but the performance takes a big hit due to the volume of records that are retrieved. So we are looking to build this calculation on the backend. Has anyone here done something similar and could share their experience on this?  To repeat, the users would like to see the life-to-date value and this will contain any amounts that have been posted to this object. I was thinking about using a standard dso for this solution and use the amounts related cubes as source for this dso. The key figures (or data fields) in the dso would be incremented from the delta loads from the underlying cubes.
Thanks for sharing your thoughts or experience handling this issue.

Answer 1

If I am getting you correctly, you are getting the following output(sample) where you are getting few additional orders for which cost$ is zero but we have &cost(life to date value) like 10002563 .
Order#          Fiscal period               $costs         $costs (life-to-date)
10001111           001.2012                 5,000             50,000
10001111           002.2012                 5,000             50,000
10001112           001.2012                 6,000             30,000
10001112           002.2012                 7,000             30,000
10001112           003.2012                 7,000             30,000
10001113           003.2012                 5,000             10,000
10002563           001.2012                  0                   5000
If this is the issue then you can put a condition on cost& Key figure to be not equal to zero.It would solve the issue.
I would request you to provide us the sample output with both the correct and incorrect orders so that we can further understand the issue.
