User requirement is to create duplicate customer field in Invoice screen and that custom field is using for some historical data, But by default we are passing current Invoice customer value and later we are allowing user to change the custom field.
so in this case is there a way to set the value for existing records through code with out refreshing/modifying the existing record.
I have tried by using field level PXDefault attribute but that will not work in my case so their any events or some code to update custom field value for existing fields.
Thanks in advance.
