I have two difficultes with adding attributes on entity when the application is running.
I have an application with just one entity (for example). During of application execution i will detect that i need to add more attributes in entity.
How do i do it? is there an option to do it?
In my application i import excel sheets and i have to create entity based on these tables or i have possibility to create entities before public application but after to public and run application, i have to add attributes based on excel sheets.
Is it possible? how?
thanks our attention
