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 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 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

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 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.

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.

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 an engineer, I want to execute analyses when I get a new future data value, so that any forecasts (either via Analysis or via a 3rd party system or via a PI Point update) can trigger analyses.

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.

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

Cp, Cpu, Cpl, Pp, Ppk

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.

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.

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.

When editing an Analysis Expression, only 4.5 lines appear. It would helpful if more lines appeared (greater than 20 lines).

The arrays in Expression and Event Frame Generation analyses are useful, but use cases are emerging where more functions are needed to reduce/calculate the arrays in more streamlined fashion. For example, Concat function should support array of characters to construct a string.

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 AF Administrator, I want to configure an Analysis Template for Event Frames with a True For parameter that would have it's value stored in an AF Attribute (configuration item). The use case is that elements built from the template will have Event Frames that will require a different True For value. I would like to have the analysis both base off a template and with the possibility of having different True For values. It would also be nice to have a True For parameter for the End Time. This is already a request:
