Copying the data into internal table without internal table

Question

Hello experts.
i have two internal tables . itab1 without headerline and itab2 with headerline. itab1 has 10 fields and itab2 has 2 fields.
BEGIN OF itab,
lifnr LIKE lfa1-lifnr,
ktokk LIKE lfa1-ktokk,
name1 LIKE lfa1-name1,
sortl LIKE lfa1-sortl,
pstlz LIKE lfa1-pstlz,
ort01 LIKE lfa1-ort01,
land1 LIKE lfa1-land1,
j_1ipanno LIKE j_1imovend-panno,
end of itab.
DATA: itab1 TYPE STANDARD TABLE OF itab.
data: begin of itab2 occurs 0,
lifnr like j_1imovend-lifnr,
j_1ipanno like j_1imovend-j_1ipanno,
end of itab2.
now i want to move the data from itab2-j_1ipanno into itab1-j_1ipanno.
Both the tables ie itab1 and itab2 has lifnr data in them .
so in itab2 j_1ipanno has pan number for the lifnr( vendors) so i need to populate this pannumbers in itab1 also by comparing
the lifnrs in two tables. where ever the lifnr of itab2 is equal to itab1-lifnr then this pannumber should be placed there. 
so pls tell me how to do that. lifnr in both the tables are the same.
thanks for all the replies.

Hi Shiva,
            Try this one..
data: begin of itab.
   lifnr LIKE lfa1-lifnr,
    ktokk LIKE lfa1-ktokk,
name1 LIKE lfa1-name1,
sortl LIKE lfa1-sortl,
pstlz LIKE lfa1-pstlz,
ort01 LIKE lfa1-ort01,
land1 LIKE lfa1-land1,
j_1ipanno LIKE j_1imovend-panno,
end of itab.
data: wa like line of itab1.
data: begin of itab occurs 0,
        lifnr like j_1imovend-lifnr,
        j_1ipanno like j_1imovend-j_1ipanno,
end of itab2.
data: wa1 like line of itab2.
loop at itab1 into wa.
itab2-lifnr = wa-lifnr.
itab2-j_1ipanno = wa-j_1ipanno
append itab2.
endloop.
