Note
caralegal is very precise about the connection between purpose and legal basis. You can only select one legal basis for one purpose.
If you would like to specify several legal bases for the same purpose, please use the “Add” function described here and copy the purpose if necessary.
Add a new legal basis to be able to select it
Navigate to the section
Resources > Legal bases
There you have the option of creating a new legal basis so that you can then select it in processing activities.
