Invoice: How to use more than one Internal Table's info in one Table

Question

Hi ,
I am doing an invoice, and have the info from internal table wa_itgen showing - Matnr, material description and quantity.
I want to also invlude the info Unit Price and Total price on the table line, but can't seem to do it.
I know that someone I must fill an internal table as I did on the Table itself : is_bil_invoice-it_gen INTO wa_ITGEN.
                 ( TYPE IBBIL_INVOICE).
So now I need to insert:
IS_BIL_INVOICE-IT_PRICE    INTO      WA_ITPRICE.
Do I insert Program Lines, or do it via a LOOP.  Obviously it needs to go under the same Table's cells to incluce it.
I tried a LOOP, Program lines under the CELL of the table where I want it displayed, and even a Second table.
If I have the first table's info, the page displays under VF03, but as soon as I try to insert the 2nd Table's info, under VF03 the screen just not show anymore.
Please help - I've started looking at local maps for bridges... yes, to jump from...

Hi try this,
in the program lines fetch unit price and total price based on ur invoice number(as u are already in main loop which fetches invoice no material no etc).
now loop that internal table with condition inv no = current invoice no and item no = item number
and display those values on a new text field accordingly.
sample code...
select vbeln
       posnr
       j_3asize
       FKIMG
       KZWI1
       from vbrp
       into table itab
       where vbeln = GS_IT_GEN-BIL_NUMBER.
loop at itab into wa where vbeln = GS_IT_GEN-BIL_NUMBER and
                           posnr = GS_IT_GEN-ITM_NUMBER .
move : wa-j_3asize to v_grid,
       WA-FKIMG TO V_QTY,
       wa-KZWI1 to v_val.
       v_up = v_val / v_qty.
endloop.---->like this
