Hi dheeraj,
The part of the code which you are showing us must be in a module which is called in the loop of the table control , in the flow logic.
PAI section.
loop at no_temp."
module user_command_0100.
endloop.
module user_command_0100.
WHEN 'FETCH'.
MODIFY NO_TEMP INDEX TEMP_DET-CURRENT_LINE
FROM NO_TEMP TRANSPORTING ZCHECK.
REFRESH IT_PO_DET.
CLEAR IT_PO_DET.
endmodule.
