How to dynamically choose which view to display in second step

Question

Hi Guys,
I am just started to evaluate fpm to decide whether to use it in our project. So i have question that might be very simple to you all, that i hope you all can help me with.
Say i want to use the fpm GAF with a single webdynpro component. I have 3 steps, first step display a dropdown list for user to choose, second step will be a view that will depend on user input on the first step and 3rd step just a confirmation screen.
I plan to use UIBB for all the screen, not using the GUIBB. So i will need to dynamically decide which view to show on step 2, and since we don't call navigation plug when we use fpm, what is the best way to archive this? How do i design my webdynpro component and the fpm configuration etc...?
I read from the programming guide about initial screen and variant. But what if my application doesn't need an initial screen and the user choosing step is not at the first step, I can't use variant in this case right?
thanks.

Hi
You can give the dropdown on initial screen and than u can decide which screen  to show on the second (or infact that will we the first step you you have first step as a initial screen.
How?? :
1. Create different varients for the second step.
2. Basis on the Value choosen in the dropdown list, select the appropriate varient using the following code.
  TRY.
        CALL METHOD io_gaf->set_variant
          EXPORTING
            iv_variant_id = 'VAR_CLIENT'.
      CATCH cx_fpm_floorplan .
    ENDTRY.     
where  VAR_CLIENT  is your varient.
Hope this will help you.
Thanks & Regards,
