Dynamic element search/view for rollup
As a user of Asset Analytics I would like to have more flexibility in including elements in my rollup calculation so that I would not need to build large hierarchies just for the purpose of rollup analyses.
We would need to make rollup calculations on siblings elements
Similar to request from Alexandru, customer from RWE wants the ability to select inputs from elements a specific number of levels down the hierarchy. They want to expose the rollup at the higher level but want to skip the intermediate elements.
Yes, our hierarchy allows for grouping by the type of material that the instrumentation measures (below equipment level) so this is an issue for us - workaround at the moment is to shape a simpler hierarchy to get around the problem. As I mentioned in 17219897, the ability to concatenate string text as part of the roll-up will also be useful from a data quality exception detection perspective because it simplifies the number of events generated on data point (PI Tag) level.

This dynamic rollup should store a list of Elements that met the rollup criteria for a given execution. This list should be available in PI clients so that users can see which of their Elements contributed to a given roll-up result.
Along the lines of Alexandru's suggestion, there could be a "search full hierarchy" option for the rollup.

One such flexibility option would be to allow rollup analyses to include attributes of grand child elements.
