We're intermittently seeing errorcode "A47: Insert has non-unique tag." when posting to a NIP

We're seeing errorcode "A47: Insert has non-unique tag." when posting multiple SYMBOL_LIST refresh messages in quick succession. When posting f.ex. 100 sequences of market price refresh, symbol list refresh 3 times and market price update in quick succession, we get the above message intermittently and only some of the elements in the symbol list are added/updated.

We see the same symptom when publishing.

When introducing a small delay between refreshes, it works.

Either way we do receive 100 acks.

Any idea what A47 means and why we might see this?

And, can anyone point me to a document with Error message details and meaning?

Any hints greatly appreciated.

Thank you for reaching out to us.

The error was identified in the ADS binary file, indicating that it likely originated from the infrastructure components. For further clarification, please contact the ADH or ADS support team directly via LSEG Support.

Where did this error occur—was it in the ACK message or in the status message during subscription?

Hi Jirapongse, Thank you for your reply. The A47 message is in the ACK message.

I will make a LSEG support ticket as the A47 message is not mentioned in any of the ADS/ADH sysadmin guides.

Kind regards,

I found it in the ADS binary file.

This might not be documented.
