Compound key attribute A compound key attribute is an attribute whose primary key is made up by the combination of two or more columns. The multiple columns are joined with other attributes, typically in a many-to-many relationship . To create a compound key, users must create multiple attribute forms, group them together and set the form group as the key for the attribute. Use the same steps as specified in the help menu: Open attribute editor (right-click on attribute and select 'Edit') Select the forms that will make up the compound key From the 'Edit' menu, choose 'Group' NOTE: Modifying the key form will trigger required updates when saving. This may make related application objects (reports, filters and metrics) unusable. Click on 'Yes' to continue, when prompted, in a dialog box, to confirm this action Save the changes.
