Hi @Abhimaitri M
There are two ways possible that I think of right now.
1) You have to create clients variables which you will have to bind to all the inputs in screens (one and two) then save the data.
2) You can achieve this use case in one single page by wrapping OutsystemsUI "Navigation\Tabs" widget.
you can have the first two fields in tab 1 and other fields on tab 2 then you can altogether save all data.
Hope that will solve your problem.
cheers...
