BHTML: transporting multi level internal table

Hi gurus,

I have a two level internal table which needs to be sent to ITS using field-transport so that I can display them using BHTML.

I used field-set and field-transport for one level internal table but could not succeed in multi level.

Please help.

Eg:

data: begin of struc,

abc type i,

def type d,

end of struc,

begin of itab occurs 0,

xyz type char20,

tab like struc occurs 0,

end of itab.
