The save output history checkboxes are currently greyed out when trying to map a variable to an output attribute when creating an analysis template. I have several analyses where I don't want to create Pi Points.
It is now working and I don't believe I have changed anything. The mystery continues.
Can you tell us more about which methods are involved in your calculation?
There are several methods used in analysis whose output much be a PI Point. In particular, methods that are expensive or expect previous values.
A list of analysis that require your output to be saved:
It is possible to also use data reference "None", but this will have an adverse performance impact on your AF server and is not recommended.
The analysis I tested before was a simple If-then statement
It may be version issue. You can have newer PI System Explorer, but your AF Server and Analysis Services are older and not supporting Analysis Data Reference.
I tried recreating what you showed in the screen grab, but it is never grayed out, not even when i provide a wrong syntax
Can you post a screenshot of your configuration? It may also be good to understand why you do not want to create PI points. For example, if this is part of a rollup, you may run into some other issues.
If you are actually seeing it not grayed out, is this the same server? What is the difference between the configuration that works and that doesn't work?
I think both Wojciech and Jerome have the right idea. There are, indeed, certain restricted methods. If you are not using any of them, it could be a versions issue. It sounds like your PI Analysis Service version could be pre-2.7.0 as could your AF server version. If your PSE is post-2.7.0, you will see the options to be able to configure an Analysis data reference, but it won't work with a pre-2.7.0 PI AF Server and PI Analysis Service.
Guess that might have been some temporary issue. Happy that its resolved
