Hi @amzzz ,
Do you mean that a column is added to a table in the database and that table is used as the data source for the Tabular Model?
If so, you can do as follows:
Edit Table properties:
Refresh Preview and check new column, then click "OK":
Or see more: Update Tabular Model when the underlying Relational Database schema changes.
If I misunderstand what you mean, please feel free to corret me.
Best Regards,
Joy
