SWIFT MT Message SEME Uniqueness

Question

As far as I understand, the SEME (sender's message reference) attribute of a SWIFT MT message has to be unique per sender (it is the sender's responsibility to ensure uniqueness). So, let's say there are two sending entities A and B and I am the receiver. Then it would be a valid scenario to have both of them send out a SWIFT MT message with the same SEME, right? How could I differentiate messages coming from sender A and B? What is common practice in such a case?

In the documentation (MT 558 in that case) it says:

Reference assigned by the triparty agent to unambiguously identify the message.

You use a combination of SEME, TCTR and TRCI iirc. – Burhan Khalid Jul 11 '18 at 06:00 — Burhan Khalid, Jul 11 '18 at 06:00

The MIR in the {2: Application Header Block} seems to be the one according to me. MIR: message input reference, unique identifiers containing the date, logical terminal (including branch code), session and sequence numbers. Info source: https://www.prowidesoftware.com/about-SWIFT.jsp
