When an element is copied as reference (parent-child) elsewhere in the tree it then has multiple parents. One of it is the primary parent. This information needs to be added to the hierarchy tables.

PI AF SDK - Search Query Syntax - Filters

Allow results to be ORed. Currently Results can only be ANDed.

Both AFImport.exe and ImportXml (AFSDK) have options to continue on error (like is something is checked out or if there is a duplicate element name). For some reason the PowerShell version doesn't. This should be added.

Add support for AFElement versions to PI Web API.
1. Create a new Element Version by defining the effective date and an optional version comment. 2. Add Get and Find methods which support querying AFElements by setting a QueryDate.

Currently when searching for event frames, a 400 error is returned if not all elements in the search exist.

piwebapi/eventFrames/search?databaseWebId=WebId&Element:IN("\\server\AssetSwap\Site2\Asset1";"\\server\AssetSwap\Site2\Asset2"

This is cumbersome especially in the case of asset swapping in PI Vision when parent elements could contain variable child elements. For any parent element that contains less than the max child elements, a 400 error will occur when searching for event frames for related parent elements.

Enable functionality for PI OLEDB Enterprise that will allow the client to specify which member of a PI Data Archive collective they wish to connect to. This functionality has already been enabled for PSE and would like something similar for PI OLEDB Ent.

As a Web API developer, I would like to be able to use time PE functions in the Web API using the streams/streamsets controller to allow for complex time queries.

As a PI Web API developer, I would like to retrieve values by specifying a count like you can do in PI SMT and other PI clients. This functionality is exposed by the RecordedValuesByCount in the AF SDK.

Allow PI OLEDB Enterprise access to AF Tables.  The current workaround is to have the table live on a SQL database and then link to them from AF.

'Time Zone = Server' is available in PI OLEDB Provider, but has not been added to 'PI OLEDB Enterprise'.
We have PI Data Archives in multiple time zones and require the ability to select the data in the server time zone.

The UpdateValues method does not implement by itself the exception mechanism. Exception is applied on the client side, for instance by UniInt interfaces.

As a developer,  I would like this fact to be mentioned in the documentation to avoid confusion:

As a user, I would like to restrict connections from the PI OPC Server to only some members of the KST by either implementing a whitelist or a blacklist.

In the PI OPC DA/HDA Server 2010 product, there was a “Create Timestamps” functionality (found in the OPCServerConfig Tool). This option had the PI OPC Server create timestamps for OPC clients. I rely on this functionality heavily for an OPC client I use every day. Thus, currently I have to stay on PI OPC DA/HDA Server 2010 since this functionality was removed from the newer version. I would like to have this functionality back.

The channel/websocket feature of PI Web API would be more useful if it was possible to subscribe/unsubscribe to attributes on an existing channel connection. Currently you have to open the connection with all the WebIds you want in the resource URL. If you want to change which values you are receiving, you would have to close the connection and open a new one. Adding this new feature would also solve issues with maximum URL length limitations.

As a PI user, I want the OPC DA and HDA Servers to honor the Windows identity of any connected OPC client.

Provide ability to specify ID (Guid) when creating elements or attributes in AF via the AF SDK.

When replicating data from an external system to AF, we need to be able to use the same GUID that has already been established.  This will allow us to easily query data from PI Web API because the GUIDs can be directly translated into WebIDs without having to perform lookup queries first.

Posted on behalf of a customer:
Currently, we should go into method/object details page in order to check if the method/object is obsolete. Documenting this as a list should help any application developers to know the changes clearly.

We are building java client to access PI server via PI web API . we can not see nay sample on git on java to access it. Can you please help us.

I would like to be able to have conditionals in my requests to the batch controllers.
Consider this use case : I want to create an element and its parent, but the parent may already exists.

At the moment, I have to make 2 seperate calls: One to check if the parent exists. Then a use the appropriate batch requests to create only the child or create both the parent and child
