You can edit individual OnBase Keyword Type values from the Content Data Fields screen in Costpoint. This screen is displayed by clicking Attach to display the Linked Content Files screen and then clicking the Content Data Fields link.
Any changes made in the Value column are applied to the OnBase document when the Costpoint record is saved. Only Keyword Types that have been mapped to Costpoint data fields and configured as Editable can be edited in the Content Data Fields screen.
