How to skip a step in FPM GAF variants

Hi experts,

I have an FPM GAF variant in which i have 6 steps.

Based on some condition in step 2, the step 3 need to be shown or skipped.

If i click on the next or pervious button to move to the screens it is working fine.

But the problem is if I directly click on any of the blocks after the 3 block ( say 4th block )  since there is a code to raise it to the next block to skip 3 rd one it is going to the block next to the one I selected ( Say  5th block ).

PFB the code used to raise to the next screen.

                 lr_event = cl_fpm_event=>create_by_id( cl_fpm_event=>gc_event_next_step ).
*       raise event
                wd_this->mr_fpm->raise_event( io_event = lr_event ).

kindly give some suggestions.

Thanks,

Nalla B.
