HI happy,
In export parameter u have declared itab_table right,
that is not a internal table that is work area
u have to define Itab_table in tables Tab.
follow this logic
write the code in source Code.
select * from kna1 into TABLE itab
where kunnr = cust_no and
name1 = name and
land1 = countryname.
output:
after executing u will recieve detail in ti internal table..
Award points if useful
regards,
arun prasath
