Need Functionality of F9 of selection screen in button click

Question

Hello Friends,
i am working on a report.
the selection screen have one selection field material.
1)  if the material is not entered on ss
2) a popup appears to run program in background. this logic was done in at selection-screen  event.
3) if we press ok from the popup. then need to run the program in background as it is done in f9.
i.e. i mean to say is. i need the same functionality as we get in F9.
Process in F9 :
1) A printer specification popup appears.
2) then scheduling batch job appears. where we create a batch job manually.
you could try going in t.code -- V_V2 and press F9. You could obtain the same functionality as i am trying to describe.
Note: we need to set the job manually.
Thanks!!
Rachit.

Hello,
You can implement the background job functionality by manually calling the background job from the program.
For this you need to implement the following three steps : -
1) Call the FM "JOB_OPEN" to open the background job. Provide the job_name to the FM and get the job_count.
2) SUBMIT the same Z program which you are currently running using the below code.
SUBMIT (sy-repid)
            WITH SELECTION-TABLE lt_rspar
            TO SAP-SPOOL
            SPOOL PARAMETERS ls_print_parameters
            WITHOUT SPOOL DYNPRO
            USER sy-uname VIA JOB job_name NUMBER job_count
            AND RETURN.
Table  lt_rspar is  TYPE STANDARD TABLE OF rsparams, through which we pass the parameters entered on the selection screen to the background program.
RSPAR-SELNAME = Name of the select options/ parameters for which you want to pass the value
RSPAR-LOW         = Low value in case of select options/ values in the parameters
RSPAR-HIGH        =  High value in case of select options.
Append all selection screen values to the internal table LT_RSPAR as per the above rule.
The printer name and the formatting options can be passed via print parameters workarea ls_print_parameters
ls_print_parameters TYPE  pri_params.
After this code, we call the FM "JOB_CLOSE" to close the background job.
