Answer 1

Exit to be used is   EXIT_SAPLEBND_002. Enhancement M06E0004.
DATA it_ekpo TYPE LINE OF mmpur_bekpo .
To have controls in system for Standard Cost Estimation under two conditions if SCE is not run then,
1)      System will not allow creating Process Order (COR1).
2)      System will not allow Post Goods Issue (VL02N).
Till date we do not have any control of SCE while creating Stock Transport Order.
Now we have another control for SCE, that is
3)      Henceforth system will not allow creating STO (ME21N).
IF sy-tcode = 'ME21N' OR sy-tcode = 'ME22N'.
  IF i_cekko-bsart = 'UB'.
    LOOP AT it_bekpo INTO it_ekpo.
      SELECT SINGLE mtart FROM mara INTO mara-mtart WHERE matnr = it_ekpo-matnr .
      IF mara-mtart = 'IFIG' OR mara-mtart = 'ISFG'.
        SELECT SINGLE * FROM mbew WHERE matnr EQ it_ekpo-matnr
                                            AND bwkey EQ it_ekpo-werks.
        IF mbew-vprsv = 'S'.
          SELECT SINGLE * FROM mbew WHERE matnr EQ it_ekpo-matnr
                                          AND bwkey EQ it_ekpo-werks.
          IF mbew-stprs > '0.00'.
            CONTINUE.
          ELSE.
            MESSAGE e004(zpp) WITH it_ekpo-matnr it_ekpo-werks.
          ENDIF.
        ENDIF.
      ENDIF.
    ENDLOOP.
  ENDIF.
