[Former Member]

Hi All,

my question about modul-pool,

i have two fields one is MARA-MATNR and second one is MARA-MTART.

if enter somthing in MARA-MATNR only second field

MARA-MTART should be ready for input

other wise it should in disble mode not for input

for suppose if MARA-MATNR equal to space

MARA-MTART field should be in output sate .

and if enter any thing in MARA-MATNR

MARA-MTART field should be change automatically ready for input.

my cose is below

  MODULE SCRNMOD OUTPUT.
                        IF MARA-MATNR EQ ' '.


                          LOOP AT SCREEN.

                            CASE SCREEN-GROUP1.
                              WHEN 'GR1'.
                                SCREEN-INPUT = 0.
                                SCREEN-OUTPUT = 0.
                                MODIFY SCREEN.
                            ENDCASE.

                          ENDLOOP.
                        ELSE.
                          LOOP AT SCREEN.

                            CASE SCREEN-GROUP1.
                              WHEN 'GR1'.
                                SCREEN-INPUT = 1.
                                SCREEN-OUTPUT  = 1.
                                MODIFY SCREEN.
                            ENDCASE.
                          ENDLOOP.
                        ENDIF.


                      ENDMODULE.

I GOT ANSWER

LOOP AT SCREEN.

CASE SCREEN-GROUP1.

WHEN 'GR1'.

IF MARA-MATNR EQ ' '.

SCREEN-INPUT = 0.

SCREEN-OUTPUT = 0.

ENDIF.

IF MARA-MATNR NE ' '.

*

SCREEN-INPUT = 1.

SCREEN-OUTPUT = 1.

ENDIF.

MODIFY SCREEN.

ENDCASE.

ENDLOOP.
