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 user, I want to be able to search for specific PI Points used by PI AF attributes, so that I can easily find where the PI Points are being used.

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

I would like to use some more advanced string functions such as Split, Len (string length), and even regex filtering to allow more fine grained control of how some input strings (such as attribute values or substitution parameters) are manipulated to create a new string output.

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 TableLookup Data Reference to be able to use substitution parameters to specify the column name(s) and table name for the SELECT and FROM fields respectively. This would allow for the use of attribute values like those from String Builder attributes to be used to identify the desired column(s) or table and facilitate the use of table lookup within Element Templates.

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.

Managing thousands of notifications can be difficult. There should be an option to export all the notifications and its subscribers. In PI Builder, you can find information about notifications via Contacts and Elements. There should be a direct way to list all the notifications.

As an administrator, I need to ability to configure the life span of my PI data, so that data are kept or deleted accordingly. For example, data that should be deleted based on corporate mandates and data that should be kept forever are handled accordingly.

Note: This was previously Enhancement 25774OSI8.

As a user, I want to be able to use substitution parameters in attribute template descriptions, so that when elements are created from template, the attribute template description can be substituted with pertinent information.

Note: This was previously Enhancement 116200.

Looking for a tool that would compare two databases (that originated from the same parent) then gives user option to keep or discard changes from each and eventually merge them to form a working production database.

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.

PI System Explorer should visually highlight attributes of template based elements that have changes to the template.

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