Interfaces subscribe to point creation/editing/deletion events so they can respond to new or changed or deleted tags. The connection that they have with the PI server must have sufficient privilege to be able to read the tag's metadata (such as point source) to determine if they should be concerned about the tag creation/edit/deletion.
The problem here is probably that the interface does not have any access to the created tag's metadata. This means that the interface received a message "point ID XXX created", went to fetch the details on the tag with point ID XXX, and was denied by the PI server.
The message is harmless, as the interface shouldn't need to access the tag, but it will clutter up your log file.
If you want to make the message go away, you must grant the interface's connection (via trust or mapping) read access in the ptsecurity section of the tag configuration.
HI Mallesh, Did you ever figure out what happened? I wanted to mention that for OSIsoft Techsupport requests, you should add your question to this space: All Things PI - Ask, Discuss, Connect. Let us know if you solved your problem!
