Use the filter in the Portfolio table to show only the projects you need, for example one department or one project manager. Save the setup as a table profile so you do not have to set it up again.
How to filter
Go to Portfolio.
Open the filter in the table and choose the column you want to filter on, for example department, project manager or status.
Choose the values you want to see. An active filter is shown with a marker in the table.
How to save the view
Set up the columns and the filter the way you want them.
Save as a table profile. Choose whether the profile should be private or shared with the organization.
Next time, select the profile in the profile selector above the table.
