Resume plug -> session problem

[shabir_ismail]

Hello experts,

i am calling an external catalog from a web dynpro application.

I use the suspend plug as follows :

  ls_url_fields-use_suspend_resume = abap_true.
  ls_url_fields-parameter = lv_apb_lpd_t_params.

  CALL METHOD lo_fpm_navigate_to->launch_url
    EXPORTING
      is_url_fields = ls_url_fields.

its going to the required site but however when coming back it is creating a new session of the web dynpro application. (the resume plug is not being called).

Can someone help me. its really urgent. is there something about the hook url that needs to be changes or some other stuff that i am missing ?

do we have to pass the session id into the hook url ??? i read a lot but i cant find the solution.

Thanks in advace
