Depending on how the Costpoint content type has been configured, you may receive a warning or error message when attempting to save a new document link if the Costpoint data field values and OnBase document's Keyword Type values do not match.
You may be able to proceed with mismatching data, Costpoint may prevent you from linking the document until the data fields match, or Costpoint may automatically update the OnBase Keyword Types to match the Costpoint data fields. Contact your system administrator for more information on how your solution handles data field mismatches.
