While creating a new Customer a new related record is created in CommunicationEvent table
Answered by Pritam Kute <firstname.lastname@example.org>:
In OOTB flow, after creating a customer, the system calls sendCreatePartyEmailNotification service asynchronously. This service is called to send an email notification to the customer about account creation. This causes the creation of a record in CommunicationEvent table.
I feel that sending email should be configurable but an initial cursory look at the codebase doesn't guarantee about it.
Also, one thing to notice is that the CommunicationEvent created has a record with partyIdFrom as FrenchCustomer which is completely wrong as it should be a company party. The logic in createCommEventFromEmail (line no. 776) to find out "fromCm" is what causing this problem.
Answered by myself:
I think found the reason. In demo data 13 parties use <<infoString="email@example.com">> as in
<ContactMech contactMechId="FRA01" contactMechTypeId="EMAIL_ADDRESS" infoString="firstname.lastname@example.org"/>
I guess this one is loaded last. Rather
<ContactMech contactMechId="Company" contactMechTypeId="EMAIL_ADDRESS" infoString="email@example.com"/>
which is the 1st one, should be loaded last.
