problem with smartforms

Dear all,

I am working on <b>smartforms</b>. i hv one problem in that. if i use one internal table in smartforms i got exact output wht i want. but if my finalitab contain data of two tables. for eg

<b>tables: MARA, MAKT.</b>

itab1 like mara.

itab2 like makt.

finalitab contains fields from both itabs i.e.

<b>finalitab</b> having fields like matnr, mtart, mbrsh, maktx

how will i define these tables into smartforms so that i will get data from two different tables. i hv tried some options but they are not working.

plz give me sample example with code as early as possible.

thanks in advance.
