As a process engineer I would like to be able to integrate complex specific calculations, such as from a 3rd party analytics engine, so that I can use the Asset Analytics and its context with all the available data and scheduling to run those without needing to do custom heavy development.

As a PI administrator I would like to be able to create multiple instances of "PI Analysis Service" windows service for these reasons:
- avoid new potentially problematic analysis from affecting the ones that are operational and working correctly by setting one production instance and one test instance for example.
- every instance could have its own log files and we could move some analyses to a new instance to troubleshoot them
- make possible to distribute the resources usage for asset analytics on more than one server

As a a user of Asset Analytics I want to see the calculation dependencies for an analysis so that I can understand which analyses are dependant on an analysis and view potential circular references

As a user configuring a Rollup analysis, I want to be able to apply a filter expression on the inputs so that the Rollup only includes inputs that satisfy a condition.

Note: This was previously Enhancement 114349.

As a user, I would like to have the option to automatic recalculation of event frame for out-of-order input events in AF analysis. The option is available for expression analysis in PI Analysis  2017 R2 but not for event frame generation analysis.

As a user of event frames, I would like the ability to be able to set a time true condition for the end trigger of an event frame analysis, similar to how this functionality is available for the start trigger

Currently in the analysis service configuration there is a parameter called “AutoBackfillingEnabled” which affects the analysis calculations in a global basis. It would be great if it were possible to disable the auto backfilling to individual calculations.

As a quality engineer, I need the ability to calculate Six Sigma SQC statitistics for key quality attirbutes. 

Cp, Cpu, Cpl, Pp, Ppk

I would like to have monthly and yearly periodic trigger for Analysis-Expression and Event Frame Generation. Currently I have to use the daily trigger and check in the analysis if the month or the year changed. In case of “false” there is no output. In the case of “true” there is an output. This works but it is circuitous.

Use case: User wants to trend Analysis Data Reference in client tools (Processbook, Coresight). User doesn’t want to create a PI tag for this output. Currently, the AnalysisDR ignores step, even if it’s input attributes are step.

As a user of analyses, I would like to have a Percentile function so that I can filter out atypical events when doing summary calls. The function would look like this: Percentile('attribute', 'timerange', value). This is related to enhancement request WI 44140.

Currently PI Analysis Service has a built-in Statistics tool in PI System Explorer.

It is able to show statistics regarding Evaluation and Calculation Lag as well as Skipped Evaluations and some other important information.

PI System Explorer could run these statistics periodically and notify the user (in the Management tab or in the Analysis tab itself) whenever a PI Analysis has its parameters out of certain values (could cause a bad performance)

So that the users could avoid performance issues more easily.

We currently have Event Frames generating for machine faults, with child event frames then tracking things such as maintenance team response time etc.
Leveraging this data in excel reports is proving difficult however due to the Child Event Frames having the same template and naming convention as the parent.
If Child Event Frames could have custom naming or different templates it would be extremely valuable

As a user of Asset Analytics I would like to manipulate data quality related flags (such as quastionable, substituted, etc) from my analysis so that I can set the flag when there is a problem with input value statuses.

As an analysis user I would like to define what should happen if multiple triggers occur with the same timestamp.
Currently AF analysis are using "Replace" mode when writing to the archive (meaning if multiple triggers have the same timestamp, the last one will overwrite all previous ones). AF SDK supports using "Insert" mode (which allows for multiple values having the same timestamp). I would like to have an option to select the write mode for each analysis.

Use Case: calculating which Shift is working within a rotating-shift cycle, which must the follow Daylight Savings Time offset.

This function is available in the Performance Equation library, but not in AF. The function itself is simple once one knows it, but is not obvious (kudos to Nicola Gargano):

IsDst = Floor(Float(''-'1-jan') / 3600) Mod 24 <> Hour('')

It should be added to the AF function library.
