If an existing digital state is edited, PI Analysis Service does not recognize the change until it is restarted. A digital state should not be edited too often. However, it would be useful if there is a process to update cache, including each digital state, which PI Analysis Service uses.

I would like the ability to flag an SQC event only if I am in a batch, on a grade run, or in some other process condition. Right now, I am getting an SQC outside control limit when my phase is "inactive." Let there be more configuration of this in the analysis configuration.

When input PI Tags are referenced in PI Vision 2020+ calculations, they do not automatically detect PI Tag name changes. For users with a lot of calculations, this can be extremely problematic in the event of a PI Tag name change. In the event of a name change, the following error is produced: [-12301] Performance Equation parsing error. Possibly updating the PE scheduler to reference the PointID instead would be beneficial.

As a PI server Administrator I would like to have a way to decide the PI DA collective member Analysis server should connect.
This will allow us to manage better the load on PI DA

It'd be nice to dynamically set the Event Frame category within Asset Analytics.

Preferably have this as an option for each 'Start Trigger'.

This would be advantageous since 'category' is on the top level object and thus much more efficient to query than needing to go down into the EF attributes in order to filter further.

Give analyses format function the ability to format timestamp similar to the one in the formula data reference. e.g. Format (datetime, "dd-MMM-yyyy HH: mm: ss");

Please provide a 'GoTo' like Funciton for Analysis Expressions to skip expressions or maybe even go back to a previous Expression.
I realize you don't have line numbers per se, but if the Expressions operate in order, could you use the Variable Name?
This would be extremely useful for skipping a block of code under certain scenarios where it's just too difficult for a mile long nested if/then.
@ Kevin G., don't decline this, vote for it ;)

There are no number base conversion functions available in AF Analysis. There are many situations where I need to convert numbers between different 'number bases'. I frequently work with MODBUS devices and there are many times number base conversions are needed to properly get data.

Example: Convert decimal to hex, hex to binary, etc.

I test many of my functions using Excel before implementing them in Analysis. Excel has functions such as HEX2BIN, DEC2HEX, etc. I'm actually surprised that, after many years of AF/Analysis development, these type functions are not available. These are valuable functions that should be implemented.

There is a considerable amount of downtime in our system (20+ minutes) when a template change is performed. The root cause is a limitation on how the analysis service handles the removal of AF Attributes from the Data Cache. Due to this limitation it takes a considerable amount of time to rebuild the cache.

While it is possible to manually calculate Process Capability Statistics, such as Cpk and Ppk, using AF Asset Analytics, it would be much more convenient to have a built in function to calculate these values, specifically in relation to the SQC Western Electric rules analyses available in AF asset analytics already.

If an analysis with multiple trigger attributes is triggerred, it is difficult to assess which attribute produced the trigger. Hasvaluechanged has it's limitations, and comparing PrevEvent is also cumbersome.

Instead of only receiving a timestamp for the Analysis to evaluate, i would like to receive both the Attribute name/path and value that triggered this event.

As an administrator of my analyses, I would like to be able to get better visibility into my Error details when many of my analyses are in error.

There should be an easy way to change the default value of the shutdown flag for analysis output PI Points. Right now, the default value is True, which means my analysis will show a "Shutdown" value every time I restart my PI Data Archive. The easiest way to modify it right now is in the attribute configuration and we can't easily use PI Builder to modify this parameter.

It should be possible to map variables in event frame analysis to element attributes.

As a user of Asset Analytics I would like the UOMs to be consistent and meaningful throughout the calculations that might involve various complex operations so that the written output values are meaningful and with the correct units.
