internal table

Hello every body,

i am developing a token report for Rake the problem i am facing is first i am populating internal table with token number n its detail because in the same report user can select the type of token i.e is inward , outward , rake or sales return n resp reports can be seen now i have to first populate itab with token no n its item level data . when i am fetching rake data from other table on the basis of tokno itab is showing only one trip no because the token no is same for all the trips rest of the trips it is not showing. is there any way to appned the itab accordingly. so that against one token no more that one trip can be populated . i waould be very thnkfull if any one give the solution its urgent.
