transfer of data in screen programming

[Former Member]

Hi All,

Can u clarify how data is transfered in screen programming. as we dont write any write statement in screen programming.

i know that it will compare the screen field names with abap variables. so can anyone clarify in this point.

if i was right or wrong can any one make me clear how data is going to transfer.

Thanks

REPORT ZBHMOD2.

DATA: OKCODE1 TYPE SY-UCOMM,

OKCODE2 TYPE SY-UCOMM,

ENAME(10) TYPE C,

DNAME(10) TYPE C.

MODULE STATUS_1000 OUTPUT.

• SET PF-STATUS 'xxxxxxxx'.

SET TITLEBAR 'TIT1'.

ENDMODULE. " STATUS_1000 OUTPUT

MODULE STATUS_1001 OUTPUT.

• SET PF-STATUS 'xxxxxxxx'.

SET TITLEBAR 'TIT2'.

ENDMODULE. " STATUS_1001 OUTPUT

MODULE USER_COMMAND_1000 INPUT.

CASE OKCODE1.

WHEN 'BACK'.

SET SCREEN '0'.

WHEN 'NEXT'.

DNAME = ENAME.

SET SCREEN '1001'.

ENDCASE.

ENDMODULE. " USER_COMMAND_1000 INPUT

Hi,

You are correct.

The screen fields and abap variables compare their names and the data would be passing screen variables to abap variables and vice-versa.

If not, you have to do manually in PBO event or PAI event.

Screen flow logic will be stroed into Screen LUW and it will be passing to list programming.
