Is it possible (supported) to set quality of item in OPC UA server from OPC UA Client application?

In other words our customer need to write Value + Quality code from client to server.

You set a StatusCode in the WriteValue structure:

https://reference.opcfoundatio…..t4/5.10.4/

Not explicitly stated in the description but the Bad_WriteNotSupported description makes it clear:

The requested write operation is not supported.If a Client attempts to write any value, status code, timestamp combination and the Server does not support the requested combination (which could be a single quantity such as just timestamp); than the Server shall not perform any write on this Node and shall return this StatusCode for this Node. It is also used if writing of IndexRanges is not supported for a Node.
