I think you are probably right. It does become a bit too complex I think for most use cases.
I will write up a short blurb at some point on how to do this with a database trigger instead for those (probably absolutely no one) other than me care about. Will mark the blueprint as invalid as well. 2011/1/27 Lars Helge Øverland <[email protected]>: > Hi, > currently it works like this: We are not storing zeros for data elements > with aggregation operator sum.
