Former Member — Thu, 28 Jun 2007 15:00:12 GMT

Hello Frnds,

I hav created a module pool program where my logic is

I have 2 inputs(Number1 and Number2 ) and one output (Result)

And i hav 2 buttons ADD and subtract.

So when ever i enter some data in number1 and Number2 and press Add then it shuld Add and display in Result field

But frnds i m unable to get the output, bcoz whenever i m giving the values in input its accepting and getting vanished and the result field remains disabled.

so can anyone help me regarding this.

Thanks & Regards,

suraj

Hi,

You need to have DATA declared in your program with the names same as the names that you have given for the FILEDS in the screen painter.

Data is transferred from screen to program only if the NAMES of the screen fields and the DATA declared in the program is same.

SO Do like this

in the program

DATA: field1 type i,

field2 type i,

result type i.

Name your screens fields as FIELD1, FIELD2 and RESULT.

in the PAI of the screen put

result = field1 + field2.

That means you have some problem with your flow logic

are you using the screen fields from program or dictionary

what ever may be , you have to declare them globally.

so that you will get values.

can you show your coding.

Frnds this is wht i hav done...

First declared Number1(Text field ) Just beside that declared I/O field for that.

Same declared Number2(text field) and I/o field

Then declared Result (text field) and declared I/O field but its only output field.

Then declared Push buttons(ADD,SUBTRACT) AND GIVEN THE FUNCTION CODES FOR THOSE.

saved and activated.and then went to flow logic there i hav maintained follwing logic

<code>

REPORT ZMOD_DEMO.

DATA : NUMBER1 TYPE I ,

NUMBER2 TYPE I ,

RESULT TYPE I,

ok_code like sy-ucomm,

save_ok like ok_code.

&----

*& Module USER_COMMAND_9001 INPUT

&----

text

----

MODULE USER_COMMAND_9001 INPUT.

save_ok = ok_code.

clear ok_code.

CASE save_ok.

when '&ADD'.

RESULT = NUMBER1 + NUMBER2.

write 😕 result.

when '&SUB'.

RESULT = NUMBER1 - NUMBER2.

when '&MUL'.

RESULT = NUMBER1 * NUMBER2.

when '&DIV'.

RESULT = NUMBER1 / NUMBER2.

when '&EXIT'.

leave program.

Endcase.

ENDMODULE. " USER_COMMAND_9001 INPUT

</code>

Thanks&regards,

Hi Suraj,

You no need to use WRITE statement, as the values from your program variables wil automatically gets transferred to your Screen Variables if the names are same.

Now I have a question over here, what is the code you have written in PBO module. Just check you have not written any code which is clearing your RESULT variable.

Otherwise once again, just check the names of your screen variables and the program variables whether they are same or not. Make them same so that SAP can understand it and transfer the data from your program variable to screen variable.

Thanks & Regards,
