HI,

I am trying to find a solution to send the GP details which usually in the PD1 segment in the MDM T01 / T02 message.

I really appreciate it if anyone can share their thoughts.

thanks

Looking at [Caristix HL7-Definition V2](https://hl7-definition.caristix.com/v2/HL7v2.4/TriggerEvents/MDM_T01)

PD1 isn’t included. Is it not the purpose of other messages to pass this metadata across.  
V2 is relatively atomic and the trigger events have single purpose.
