When should I solve the structure as semi-rigid and when fully rigid diaphragm?

Any kind of structure can be solved with semi-rigid diaphragm.

If there is no A2-A3 irregularity in the structure and the system is not a story without beam, a solution can be made by accepting a full rigid diaphragm.

I get a report, I get the warning "The second order indicator value is high on any story. Increase the system rigidity". How can I fix it?
