Mon - All Omniscope files are configured with refresh behavior and a source when saved. Whenever you save any IOK file, you can re-configure future desired refresh behaviors for that file from the File > Save as dialogue:

Never - file will not refresh on open
Auto-detect - file detects change in Source and refreshes if necessary
Always - file will always refresh from Source on open

In addition, from Data > {Background} Automatic refresh you can enable a file for 'live' background refresh from Source periodically as long as the Report file remains open.

If your database is populating an IOK Source file (sometimes called a 'data-mart' or 'meta-report' IOK file), the 'downstream' or 'child' Report/Dashboard IOK files you save that have the Source IOK as their source will refresh as follows:

1. If an (un-empowered) Report IOK file is opened in a free Viewer, it will never refresh. You must save resend the file (which can be automatically done using a Server).

2. If an (un-empowered) Report IOK file is opened in an activated Desktop Edition, all refresh behaviors will be respected, including background auto-refresh.

3. If you use a ServerPlus installation to automatically refresh and save the Report/Dashboard IOK file as an EMPOWERED IOK file, then the free Viewer will act the same as an activated Omniscope and respect all refresh settings, PROVIDED the Source is always an IOK 'data-mart' or 'meta-report' file.

Thank you for your response ^^
I would ask some more about this and hope that it would not bother you too much.
What the FreeViewer see when they open a IOK file? Will they see the data which load in Omniscope block or any data blockes?

I am just not sure because when the database blockes are updated, I have to click 'Load' in the last block to get the updated data in Omniscope every time.
If I use a ServerPlus and set the database blockes to update based on the schedule, I do not need to click load to OmniScope and save file again when they are updated. Do I understand correctly?
Or do I have to publish an IOK file output and share a new IOK output file to my colleague?
Just would like to make sure that I understand properly - -'

Additional: how could I know that which IOK file is empowered or un-empowered?

Mon - Only IOK files created or saved by a ServerPlus licensed installations are empowered. All others are not empowered.

Free Viewers do not display the DataManager workspace. Portable IOK files contain only the data 'loaded' into memory, i.e only the data set represented by the blue 'Omniscope' block after the data flow has been completed by either a load or a refresh.

The automated Scheduler process included in Server and ServerPlus installations ensures that the last-defined load operation is always performed as part of the overall automated file refresh, personalisation and distribution flow and also for all auto-published outputs.

You can set your Desktop files to execute the last-defined load automatically using:
Data > Automatic refresh > {enable} and choosing the last option:
'Retreive new data, notify and apply immediately'

Thank you Thomas ^_^
