How to distinguish between different ISO 15022 SWIFT messages received for same security.

Harshwardhan

I want to understand if LSEG provides ISO 15022 SWIFT messages for voluntary corporate events and if for a particular security if multiple SWIFT messages are received then which factor can help to uniquely identify different SWIFT messages for same security.

Also does ISO 15022 SWIFT messages provides details like when SWIFT message was created for particular event.

Hi @Harshwardhan,
Thank you for reaching out!
Yes - LSEG does provide Corporate Actions data in SWIFT ISO 15022 format.
Specifically:

MT564 - for corporate action notifications
MT568 - for narrative and detailed additional information

When multiple SWIFT messages are sent for the same security or event, each SWIFT message includes a Basic Header containing the message type, date, and time. These elements help differentiate one message from another.
Here are the key fields commonly used in ISO 15022 Corporate Action messages:

20C::SEME - Sender’s unique message reference
20C::CORP - Corporate action event reference
23G - Indicates whether the message is New, a Replacement, or a Cancellation

Yes, ISO 15022 Corporate Action messages also contain date and time details. For example:

98A::PREP - Represents the date and time when the message was prepared/generated
