The feature is called common dataset (CDS). And this is how it works:
1.) You create a CDS for a particular view in a group-owned base (it doesn’t work for personal bases)
2.) You grant access to the CDS to the groups you wish have access via the CDS administration (menu item on the left on the home screen)
3.) In a base, you import the CDS in a new table.
Currently, CDS only support manual sync, meaning you have to click “Resync CDS” in the table’s context menu to resync the imported data with the source data. In SeaTable 2.8, scheduled for end of the month, CDS will also support automatic sync.
Importandt: When using CDS, data only flows in one direction. It’s not possible to write data into the source table from the imported table.
