I have a model that I create in a workbench, and one of the tables is a table of relationships of many factors with a composite key consisting of 3 integer values: two foreign keys that make up many relationships, and an additional identifier whose data is not related to my question.
I see how on the workplace model tab I can check the box so that all 3 values โโmake up the primary key component (and its index), and it seems to work fine, but when I go to the EER Diagram tab - I see only one of columns with a key icon next to it.
Is there an extra step here or is there something that I don't see?
EDIT : see attached screenshot - sorry for the yellow masking boxes - my company would not be happy if I posted the details, even for something very simple.
