Analytics & Calculations

Allow a default value to be specified for rollup analysis. This value would be used when the rollup cannot find any matching attributes, thereby eliminating a lot of rollup analysis errors and Calc Failed values from being written.

As a PI system user, I need the ability to use reason codes to develop reports and dashboards. The current functionality of PI Vision symbols and analytics do not really enable the use of the current data type of EF attribute. The ability to map ...

As an engineer I need the option to not capture values for event frames generation so that if I have out-of-order events, I don't have to recapture the values. Note: This was previously Enhancement 114349.

In order to calculate the current shift operating at a plant, I need to calculate where in the 28-day cycle the current week is. Knowing which week of the year it is allows me to do that. Note that current PI weekday functions always count Sunday ...

The PI Analysis Service has performance counters to track the number of running analyses and the number of suspended analyses, but there is not one that tracks the number of stopped analyses. Currently, the only way to monitor how many AF analyses...

Right now BadVal can only check one variable or Expression.  So if I am evaluating an expression with say 10 inputs, and I want the expression to output NoOutput() if any one of the 10 inputs are BadVal, then I have 2 options right now. ...

For recursive Analyses such as below : PrevVal(tagA,'*') + 'TagB' → output : tagA When the PI Analysis Service is down (or the node needs to be restarted), the current calculation needs to be halted until the Backfilling reaches up to the start u...

As a user configuring Analyses, I would the the Performance Equation (PE) Editor's auto-complete to suggest any child attributes as well as regular attributes.  Note: This was previously Enhancement 109589.

A useful setting for PI Analytics would be the ability to specify a specific pointsource that the Analytic service writes to. This would help tremendously to troubleshoot what tags on the PI DA server are being written to by AF Analytics.

As a user of Asset Analytics I would like to have more flexibility in including elements in my rollup calculation so that I would not need to build large hierarchies just for the purpose of rollup analyses.
