i do the firts advice but the second one i get syntax error :
my code :
PROCESS AFTER INPUT.
  LOOP  at it_zc2p_lider_modul WITH CONTROL zc2p_lider_crtl.
    MODULE read_table_control.
  ENDLOOP.
   MODULE user_command_0101.
error :
In the event PROCESS AFTER INPUT, no additions are allowed with "LOOP     
AT".
