Project Status Portal Overview widget on the Project Status Portal does not show additional columns added to JSON options
The column is not configured in the planning console settings.
Will use the "Program" column as an example.
1) On Navigator search for Project Administration > Setting > Planning Console
2) Open record where Entity is 'project' and Context is 'my_gantt'
3) In this, we have a "planning console display columns" table as a related list. Any additional columns have to be configured in this table similar to other records existing in this table for the column to show up on the Portal.
Please see below documentation for more information on the above.
