Hi,

• APPEND *******************************************

*This statement appends one or more rows line_spec to

*an internal index table itab.

TYPES: BEGIN OF ts_test,

a type BPREI,

b(10),

c(10),

d(10),

END OF ts_test.

DATA: it_test TYPE TABLE OF ts_test.

DATA: ls_test TYPE ts_test.

DATA: ls_test1 TYPE ts_test.

ls_test-a = 1.

ls_test-b = 'a'.

ls_test-c = 'test'.

ls_test-c = 'try'.

append ls_test to it_test.

clear ls_test.

ls_test-a = 2.

ls_test-b = 'b'.

ls_test-c = 'b_test'.

ls_test-c = 'b_try'.

append ls_test to it_test.

clear ls_test.

ls_test-a = 3.

ls_test-b = 'a'.

ls_test-c = 'test'.

ls_test-c = 'try'.

append ls_test to it_test.

clear ls_test.

ls_test-a = 4.

ls_test-b = 'b'.

ls_test-c = 'b_test'.

ls_test-c = 'b_try'.

append ls_test to it_test.

clear ls_test.

sort it_test.

clear ls_test1.

loop at it_test into ls_test.

write : ls_test-a.

write : ls_test-b.

write : ls_test-c.

write : ls_test-d.

write /.

endloop.
