Dear all,
I have one customized table "THK_DataExch_PurchLineReturn".
When one field "Import Status"on this table change, I have set an alert rule to send email for notification.
However, for the content, it does not have any value for field "For".
I guess the main reason is due to customized table.

Normally, for standard table, it is ok to display.

Then i trace:
This field "For" comes from table "EventInbox" > "AlertedFor".
However, for customized table, it is empty value.

I would like to know why this "AlertedFor" in "EventInbox" is empty?
Also, any suggestion on my situation?
