I want to create a custom metadata field of type Date. I want to make it mandatory and want to set its default value as system date.See http://docs.oracle.com/cd/E23943_01/doc.1111/e10726/c08_config_ref.htm#CSIDO710
I have already created field of type Date. What expression I should write to make system date as default value?
Because its a mandatory field, what would happen to existing content. Will there metadata get updated?No, it will not be updated - profiles are active only for new or updated items (in fact, they work on front-end).
