i m sending u code
Just tell me changes
LOOP AT ITAB_EMP WHERE MARK = 'X' .
    IF SY-SUBRC = 0.
      ITAB_TEST[] = ITAB_EMP[].
      DELETE ADJACENT DUPLICATES FROM ITAB_TEST.
      LOOP AT ITAB_TEST.
        CLEAR SUM .
        LOOP AT ITAB_EMP WHERE PERID = ITAB_TEST-PERID.
          SUM = SUM + ITAB_EMP-OTIME.
        IF SUM > '100000'.
          MESSAGE E018.
        <b>ELSEIF ITAB_EMP-OTIME > '010000'.
          MESSAGE E017.
        SET CURSOR FIELD ITAB_EMP-OTIME .</b>        ELSE.
          MOVE-CORRESPONDING ITAB_EMP TO ITAB_OTAPP .
          ITAB_OTAPP-OBJID = 1.
          ITAB_OTAPP-INACT = 'X'.
          ITAB_OTAPP-TODTE = ZHR_PR_M_OTAPP-TODTE.
          ITAB_OTAPP-FRDTE = ZHR_PR_M_OTAPP-FRDTE.
          ITAB_OTAPP-IMMHD = ZHR_PR_M_OTAPP-IMMHD.
          ITAB_OTAPP-CRETM = SY-UZEIT.
          ITAB_OTAPP-CREON = SY-DATUM.
          ITAB_OTAPP-CREBY = SY-UNAME.
          APPEND ITAB_OTAPP.
        ENDIF.
      ENDLOOP.
ENDLOOP.
      endif.
endloop.
    LOOP AT ITAB_OTAPP INTO WA_ITAB_OTAPP.
      MODIFY ZHR_PR_M_OTAPP FROM WA_ITAB_OTAPP.
    ENDLOOP.
BOLD lines are the condition checking
if check all the lines and then if any of the line gives error it reflects now i want to place cursor on that field which is giving error
sy-tabix will work
BUT HOW?????

Some of the logic is a bit confusing (would be easier to read if you used the "Code" button in the SDN message editor)... for example:
LOOP AT ITAB_EMP WHERE MARK = 'X' .
  IF SY-SUBRC = 0.
... the "IF SY-SUBRC" won't be reached unless there is at least one row where "mark = 'X'.''...
Anyhow, where is this code implemented currently?... the usual approach to validating a table control is to have a module called inside the "loop at table control" in the PAI of the screen flow... then the contents of each row on the screen will get passed into your logic a row at a time automatically and the "set cursor field" + "message e999(zz)" type code should work as it will refer to the current row being checked.
