neckr Need help Updating field values in after trigger
I realize that trigger.new is read only so I created a map to update the fields in my trigger but still getting a read-only error. I cut out most of my code and left the relevant parts. My code compiles but gives and error when running.
Any suggestions?

When you are doing the:
And:
You are simply making a shallow copy of the record (it will just be a reference rather than an independent record). Since it is a reference it simply points to the same un-editable data.
There are a couple of ways to do this:
1. Build a new list from a query at the start of the trigger:
You should then have an independent map that you can work with.
2. Build a new list using the deepClone() function for lists (
