This is way too hard for something so simple so I'm posting it here.


data: lr_data type ref to data,
      lt_seltable type TABLE OF rsparams,
      ls_seltable type rsparams.

ls_seltable-SIGN = 'I'.
ls_seltable-OPTION = 'EQ'.
ls_seltable-SELNAME = 'SP$00001'.
ls_seltable-kind = 'S'.
append ls_seltable to lt_seltable.
