As a power user or admin, I would like the ability to create child events (EFs) or sub events within AF Analytics SO THAT I can migrate EFGen configurations to something that can be applied to a template and not configured by tags and SO THAT my users can analyze finer time periods of events.

Most common trigger behaviors for a child event are:
* Pulse: values are 0/1 or ON/OFF
* Step: values change and upon each transition, current in-progress event is closed and a new one is created
* Step Continuous: An event is also captured in the OFF/0 state.
* A trigger expression.

The Name of the child event can come from:
* Active (trigger) tag value
* A Static name
* Another tag value at the time of creation (or delayed)

mprove PI AF Analysis Handling in PI System Explorer when working with hundreds of analysis with following features:

- Possibility to sort Analysis/Analysis Templates in alphabetic order by Status, Element, Name, Template

- Possibility to filter Analysis by Status, Element, Name, Template, Backfilling

- Select all filters Analysis to Start/Stop and Start Backfilling
Problem is when a certain set of a analyses are selected so they will be handled in one go. It is not possible to group the required ones in a contiguous section of lines in the PSE Management Add-In, manual selection is taking very much time.

- Stop Backfilling for all selected Analysis !!!
This is needed when a backfill is started and takes a long time, but during that period it is encountered that an expression correction is needed.

We have come across a number of occasions where we want to bring in the last good value of an attribute as an input to an analytics.  But there is no way to do this without additional attributes and analytics.  It would be convenient if a function existed that brought in the last good value of the attribute.  This is particularly useful when your data source is known to send NULL value frequent which translate into No Data or Bad Input.  One specific example:

We have a number of analytics that only run if one of our engine is on.  But the SCADA system we get run status from flakes out often and PI records it as No Data.  When SCADA flakes out, we assume Last Good Value.  Meaning if the engine was on before the outage, we consider it on until SCADA returns and tells us otherwise.  But if we bring the run status into an analytic, it uses the value No Data and breaks everything.  Instead of No Data, we should be able to wrap that attribute in a LGV function that will report On instead of No Data.

If an Analysis is triggered on "Any Input", and the inputs have the same timestamp but come in after each other, the Analysis is only triggered at the first input.

For example: We have a simple Analysis which summarizes 2 tag.
The first tag comes in a 14:00, with timestamp 14:00. This triggers the calculation. The second tag comes in at 14:02 also with timestamp 14:00. Now the calculation in not triggered anymore.

We've also discussed this with Techsupport, and they came with the following statement: "With Event Triggered, the first value to come into the PI DA is used by the Analysis Service. Other events with the same timestamp are ignored."
We would expect that the Analysis would be triggered again if the timestamp is greater or equal to the last incoming event.

From a varying number of child elements (all sharing the same template), I want to find the most recent timestamp of a same template-based attribute, and output the value with timestamp to an attribute in the parent element.
In addition, constantly (event-triggered/periodic) comparing the timestamps of these child element attributes and always output the "newest" value to the parent element attribute.

Example:

From 3 child elements, all sharing the same template with attribute "ALARM", I want to have the most recent value comparing the 3 "ALARM"s, and have this timestamp and value in an attribute in the parent element.

Suggestions for enhancement:

- Function in Rollup Analysis which compares timestamps of template based attributes and outputs the most recent timestamp (with value!).

As a PI user, I want to be able to visualize and analyze the SQC violations that are generated by the SQC rules. 

The ability to save SQC outputs such as  Mean, median, mode, stdev, Cpk, max, min, 1-5 sigma zones, ucl, lcl in the following ways

1) the EF associated with the SQC rule - essentially the alarm event
2) an EF associated with a process event.  I want SQC summaries added as EF attributes bound by process event frames
3) AF clients.  I want to be able to add Cpk, sigma etc for any applicable AF attribute to a PI vision screen and have the results reflect the timerange on the screen.
