Can´t find "Modified By" on RIDW.VW_REQUIREMENT view

Hi everyone!
I need to create a report that shows the last resource that updated the Requirement.
I´ve noticed that this information is not available in the RIDW.VW_REQUIREMENT view. We only have the date of the last update (REC_DATETIME).
Is there another view in RIDW SCHEMA where I can find this info? So I can make a JOIN and show what I need.
Thanks a lot!!
