I'm posting a piece of before insert/ update trigger, it has to populate custom email field on Opportunity into Account's Email custom field.
I'm trying to do something like this:
For(Opportunity opp : trigger.new)
If(!SetEmaiIDs.contains(opp.Email__c)) // checking if added email is already not present on some other account
opp.Account.Account_Email__c = opp.Email__c; // This line is throwing error
Seems like this line 'opp.Account.Account_Email__c' is not working Can't we access account field like above , it is giving Attempt to de-reference a null object: error on same line
