Answer:
In General Data, it is necessary first to select the sets of members in order to be able to design them for the corresponding limit states (see Image 01). Then, you can enter different settings for the serviceability limit state design in the serviceability data (see Image 02).
Question
Why is it not possible to select sets of members for the serviceability limit state design in the respective design modules? I cannot specify sets of members under "Serviceability Data".
