Administrators can create custom columns. The columns are usually set up once for the whole organization. Regular users therefore don't need to think about them day to day.
How to do it
Clarify which columns the organization needs, for example period columns for month or quarter.
Ask an admin to set them up.
Once the columns have been created, you can add them to your tables under Columns, like other columns. The setup itself is under Columns → Custom columns.
Good to know
Custom columns are built as formulas from existing variables.
If you are unsure who the admin is in the organization, contact us in the chat.
The columns can be saved in a table profile and shared with the project or the organization.
