Automatically Set 'Final' Status on Imported Submittal Documents
On the Storage tab, the setting Lock imported submittal documents is on by default. When on, importing submittal documents (whether by acknowledging the submittal or by manually importing a submittal's documents) will automatically set each imported document's status to Final, if the user who performs the import has their user setting turned on.
Turn this setting off if you do not want the status of imported submittal documents to be automatically set to Final.
