Allow Max Rollup to provide AF Element-attribute

Using the Max Rollup function - I would like to know which element provided the maximum value and output this as well so I can historize the information.

    If you were to historize the attribute name that had the max value, you would need to store that in a separate PI Point in addition to the values. That means you have to have a way to know that these 2 PI Points are related. Is that OK?

    In response to Stephen Kwan, "If you were to historize the attribute n..." That makes sense, 2 points would be fine/appropriate.

    I think it would also be useful on Minimum Rollup.

    Hello i have the same use case. for example i have N elements. each element contains 2 attributes A and B. I would like to get B value for the A max. So with rollup i can get A max but it is not possible to get which element provides that. If so i could get my B value. But for now, it is not possible. So getting either name of element or index, or something we can use later to obtain other informations could be interesting.

    Hello I have a similar request to this enhancement below. I'm setting up a condition based maintenance program and need to compare large number of similar elements (fans, pumps, motors, etc.) I have setup the rollup analyses which can identify Min and Max performance data but I have to manually sort through all the data to find which piece of equipment have the high or low values. Has there been any update to this request?

    Unfortunately we have not yet made the decision to implement this request.
