apelizzo1.3941015382362622E12 How to create an Apex trigger to copy from one lookup field to another within the same object?
To manage Internal Support a new custom object has been created (Helpdesk__c). When a New Helpdesk record is created, the Helpdesk.Owner and the Helpdesk.Contact must be the same. How to create an Apex trigger to copy from Helpdesk.Owner to Helpdesk.contact since they are both lookup fields?
Thank you.

Thank you.

Since you need to update the same record, it is best advisable to use before insert trigger. However, if Owner is standard field, you can utilize Userinfo.getUserId() since Owner will not be available on before insert trigger. Also, note that the current logged in user is selected as the default owner of the records which are being inserted.
Hence, on before insert the logic will become:
Helpdesk.Contact = Userinfo.getUserId();
In case if Owner is a custom field, refer to the following code:
Helpdesk.Contact = Helpdesk.Owner;
Hope this helps
here is what I am getting from it (just to clarify the Custom Object Name is "Case__c" which contains the Custom Contact Lookup Field "Contact__c" and the Standard field "Owner"):
do like this:
trigger Helpdesk on case__c(before insert)
{
for(Case__c newCase:Trigger.new)
{
newCase.contact__c=Userinfo.getUserId();
}
}
Why in this line: <for(Case__c newCase:Trigger.new)> "Case" is with " __c"
While in the following line <newCase.contact__c=Userinfo.getUserId();> "newCase.contact__c" is not newCase__c.contact__c" ?
Tha nk you for your help.
