I need your help to figure out what kind of workaround can be done for the below Known Issue in PI Vision.
IssueSometimes certain elements do not appear when expanding the AF database tree in PI Vision. The issue may occur when the PI Web API Crawler is making an incremental crawl.
For any affected elements, check to see if both of the following are true:
- The element contains an attribute that has a Data Reference type of "None"
- The element has an Analysis that outputs to this attribute
My challenge here Sebastien Raposo
Certain Attributes need not be stored as a PI Point.
Example : Analysis Expression -- TagName(), TagDesc(), and many other simple Expressions.
This expression cannot be done in String Builder.So we chose to go with Analysis Output which is not stored as a PI Point.
What can be done to these kind of simple calculations which really does not need a PI Point ?
