Hi,

Let the fields be Number1,Number2.

CASE sy-ucomm.

when '&ADD'.

outputfield = input1 + input2.

when '&SUB'.

outputfield = input1 - input2.

when '&MUL'.

outputfield = input1 * input2.

when '&DIV'.

outputfield = input1 / input2.

when '&EXIT'.

leave program.

Endcase.

Regards,

Priyanka.

go to the layout editor of ur screen and click on the Dictionary/Program fields window(or click the function key F6), in the pop-up click on the button 'Get from Program' which lists all the variables declared in ur program, now select the variables and click on continue button.

The varibles that are declared in the program can now be seen on ur screen, now perform ur arithmetic operations on these fields in the PAI of ur screen and populate the value of the result in the corresponding varaible.

Lets say your two inoput fields are called X and Y and you output field is called Z.

Your PAI should look something like this:

PROCESS AFTER INPUT.

MODULE USER_COMMAND.

The code in your user command module should look something like this:

MODULE user_command INPUT.

CASE sy-ucomm.

WHEN 'ADD'.

Z = X + Y.

WHEN 'SUBTRACT'.

Z = X - Y.

WHEN 'MULTIPLY'.

Z = X * Y.

WHEN 'DIVIDE'.

Z = X / Y.

ENDCASE.

ENDMODULE.

You don;t really need anything in the PBO.

Hope it helps

u've to create 4 different push buttons(for each arithmetic operation) and assign the function codes(&ADD,&SUBSTRACT,&MULTIPLY,...) to each of them.

The function code of a pushbutton, checkbox, radio button, or dropdown box on the screen is set in the corresponding element attributes.

Follow the simple example quoted by Rajesh demo_dynpro_push_button, how can you go wrong?
