In ABAP Workbench, how do I make the program return multiple table fields in a table when a button is clicked?

问题

I am new to SAP/ABAP Workbench and I am trying to create a program that allows a user to input a foodCode in order to receive the Item and Description after the press of a button. Is there a way the results can be put in a table on the same screen? How?

report demo.
tables food.

SELECTION-SCREEN:

SELECTION-SCREEN BEGIN OF BLOCK SEGMENTVALUE WITH FRAME TITLE A1TITLE.
SELECTION SCREEN BEGIN OF LINE.
PARAMETERS P_INPUT(10) TYPE C OBLIGATORY.
SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN PUSHBUTTON /2(40) B_RESULT USER-COMMAND BUT1.
SELECTION-SCREEN END OF LINE.

INTIALIZATION.
    PERFORM SELECTION_SCREEN_TEXT.
FORM SELECTION_SCREEN TEXT.
    A1TITLE = 'Please enter food code'.
    B_RESULT = 'Return results'.

I hope I got you're question right.

Create a Report with a Dynpro.
Add a Subscreen on the top of the Dynpro and a Custom-Container on the Bottom
Mark your Selection-Screen as Subscreen an call the Dynpro-Number from your Selection-Screen in the PBO as Subscreen.
Handle the Button click in the PAI
Display the Data with an SALV in your CustomContainer

Here's a detailed explanation: http://zevolving.com/2008/10/display-alv-report-output-in-the-same-selection-screen/

I think the easiest way to do that would be yo use a Reusable alv grid that displays the results.

The function to create that look it as Reusable* alv* grid, it contains some parameters that define the screen in a table.
