Answer 1

Hi,
please check this :
data : begin of itab occurs 0,
field(1),
end of itab.
data wa like itab-field.
data n type i.
data idx type i value 2.
*ITAB contains :
*A
*B
*C
move 'A' to itab-field.
append itab.
move 'B' to itab-field.
append itab.
move 'C' to itab-field.
append itab.
*Getting index of last entry from ITAB
describe table itab lines n.
*Reading last entry of ITAB
read table itab index n into wa.
*Inserting it to wished position
insert wa into itab index idx.
*Deleting last entry (don't forget to increment the index as there is 1 more entry in ITAB now)
n = n + 1.
delete itab index n.
*ITAB now contains
*A
*C
*B
loop at itab.
  write :/ itab-field.
endloop.
