When a user attempts to archive a document using interactive ad-hoc archival, the Keyword Type fields may display a value of NULL.
This behavior typically indicates the SharePoint value is incompatible with the OnBase Keyword Type, either because the SharePoint value is too long or because the data types are incompatible.
If the SharePoint value is too long, you may need to increase the maximum length of the OnBase Keyword Type, as described in the OnBase Configuration help files.
If the data types may be incompatible, check the column mapping for the content type, and address any incompatibility issues. For more information, see Compatible Data Types.
