With the new JO, we no longer have the mean to map fields.
One of the field that previously required mapping was to add the Person ID in the AO Email log object.

It seems that functionality is now automatic taking care of and dependent on the Person Email address.
- Even if the Email address is not the unique identifier in the instance.
- Even if we provide the Person ID we hope the program will use.
In my example, I had two person record sharing the same email address.
When the program sent the email, the program would record the email being sent, but associate that email to the wrong person record in the AO Email log object.
The solution was to invalidate the duplicative email address.
We need to bring back the field mapping functionality so we can tell he program which field is for what based on the query design.
