This screen can be accessed via 'Go to - Substance'. Choose a substance and then place this screen in edit mode using the pencil. On the tab 'Linked to' you can then use the button 'New' above the overview 'Departments' to link departments to the current substance.

After opening the screen you can enter a start and end date within which the department will be linked to the substance. If you do not enter a start and/or end date, this will not be used to determine whether the link is still active.

You can then select one or more departments in the department overview by checking the box at the beginning of the line. You can use the search field to filter the overview. Any selected departments will remain selected if you enter a new search term. When you have selected all the departments you want to link to the material you can actually link them to the material by clicking on the 'Add' button in the top right. The department overview will be rebuilt and departments already linked will no longer be visible.

When you have linked all the desired departments to the substance, close the screen using the 'Close' button. The departments will become visible with the material but are not yet linked. Only after clicking on the button 'Save' the departments will be linked to the material.
