Hi Team,

One of my client faced this issue "A46: Item was reopened under new stream." recently.

As you mentioned in link

“A46: Item was reopened under new stream.” — LSEG Developer Community

, the client may have duplicate subscription in the batch request message(s) and closed the first stream. Why there is no data update for client's application after this error happen ? ADS how to handle the second stream?

what should client do if face A46 error ?

thanks

    Thank you for reaching out to us.

    Each opened item will have a unique stream ID. For example, the following item request assigns the stream ID#5 to JPY=.

    {
    
    "ID": 5,
    
    "Key": {
    
        "Service": "ELEKTRON_DD",
    
        "Name": "JPY="
    
    }
    
}

    The application will retrieve updates of JPY= with the stream ID#5.

    While this stream (#5) is opened and the application sends a new JPY= request with a new stream ID#6. 

    {
    
    "ID": 6,
    
    "Key": {
    
        "Service": "ELEKTRON_DD",
    
        "Name": "JPY="
    
    }
    
}

    The server will send the closed stream message on the stream ID#5.

    [
    
    {
    
        "ID": 5,
    
        "Type": "Status",
    
        "Key": {
    
            "Service": "ELEKTRON_DD",
    
            "Name": "JPY="
    
        },
    
        "State": {
    
            "Stream": "Closed",
    
            "Data": "Suspect",
    
            "Code": "AlreadyOpen",
    
            "Text": "A46: Item was reopened under new stream."
    
        }
    
    }
    
]

    This means that this stream ID#5 has been closed and the application will not receive any messages on this stream. The update messages of JPY= will be received through the stream ID#6 instead.
