Submit progrm for FBL5n

Dear Friends,

I need the output of FBL5N based on some inputs so i used SUBMIT statement but my doubt is how would i get the output data..

Pls kindly help me.. i searched alot but did nt get any solvable answer.

SUBMIT rfitemar WITH dd_kunnr EQ wa_final-kunnr

                   WITH dd_bukrs EQ wa_vbak-vkorg

                   WITH pa_stida EQ p_budat

                   EXPORTING LIST TO MEMORY

                   AND RETURN.

I checked in FBL5N the output is coming to internal table it_pos.

how would i get that data into my internal table or same table data.
