L2-DA Course Problem

I wanna start solving the exercises provided by you in L2-DA, i finished the basic proficiency course but I really do not understand how can I start solving the Flow Variable and Component exercise From the output table of the Processed Customer Data metanode, i can’t seem to find the processed customer data that I should resolve, in the courses you should have had guys that solve the exercises we have on the platform, not just explaining everything the app does, anyways, HOW DO I FIND WHAT TO RESOLVE.
