Select the Catalog separation tab.

Project keys can be found in the project file and media variables are displayed on the tabbed page Documents.

Once selecting a project on the left, settings of the chosen subcatalog (depending on selected tab) are displayed on the right, which are executed during the separation process.

Once all settings are made, in the Extras menu, click on Separate catalogs....

-> The same-named dialog box is opened.

Under Catalog selection, activate the desired catalogs.

Optionally, activate Adjust project date (when changing settings):

Note Normally, the project date should not be adjusted! In exceptional cases, may be if the visibility state of columns has been changed, when this option is activated, then only at changed project the date is adjusted.
