I’m sure this has been addressed before but I can’t seem to find the answer. In a trigger on a record, aside from the actual fields on the record, what do I have access to? The parent info? that record’s children? Do you just add the fields by re querying in your handler?
Answer
All fields on the Triggering object are available, but if you want any parent or child records, you will have to query for them
