Sample code in PBO and PAI

Hi all,
i created a new field in the customer master (xd03) screen with a button. if i click that button, it will display the next screen with the new field. now i need to write the code in PBO and PAI events in that screen to get the data from table and to change the already exiting data.
can any body provide me the sample code wht to write in the PBO and PAI eventts.?
thanks in advance.

Hi,
I think you find the answer but i still answered your question.
You can use the function module 'DYNP_VALUES_READ' to read value you want and use the function module ' HELP_VALUES_GET_WITH_TABLE' to get the values from kna1 table.
Good luck.

Why do we need to code loop statement in both PBO and PAI in Table control

Hi friends,
i have 2 questions-
Q1-why do we need to code a loop and endloop statement in both PBO and PAI in Table control,sometimes even empty as well?
Q2-what r d dynpro keywords?

Hi,
It is required to pass information from internal table to table control so we loop it in PBO and to get the updated information back, we loop in PAI and update internal table content.
To get more knowledge on Table controls check these threads -

Screen enhancement in ME51N - control is not passing to PBO and PAI of exit

HI ,
I am doing screen Exit for the Tcode : Me51N / Me52N.
I have to add 3 Text fields in item level, i am using Enhancement:MEREQ001(in CMOD).
Initially i added those 3 fields in Structure CI_EBANDB.
Then i designed Screen in Screen Exit:SAPLMEGUI Screen Num:111.
Here in the PBO and PAI Module
MODULE STATUS_0111 , MODULE USER_COMMAND_0111.
the control is not going , i tried with break-point inside these modules.
But while executing ME51N , debugger is not working.
Code i wrote in both PAI and PBO
MODULE STATUS_0111 and MODULE USER_COMMAND_0111.
loop AT SCREEN.
       screen-output = '1'.
       screen-input = '0'.
       MODIFY SCREEN.
endloop.
I need to display the three screen in Display format not in editable format.
Thanks and Regards,

Hi
You need to write the code in PBO of that screen based on TRANSACTION TYPE.
there is a method call 'get_transaction_state' from this you will get the transaction type (H - create , 'V'- change 'B' -display) at run time.
If run time transaction type = B
LOOP AT screen.
      IF screen-name eq c_name . "field names
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
endif.

Screen exit for co11n and problems in writting the PBO and PAI Logic ?

Hi People,
I am developing a screen exit for transaction co11n. I have found the exit ( CONFPP07 ) ... I created a project and have
assigned this exit and activated the project. I have created a field named SHIFT on clicking this field i have to give three
possible values (a,b,c ) and i have to store these values in some table .......... now my problem is in which include i
have to write PBO and PAI logic ... should i have to write pbo logic in the include provided in the exit
EXIT_SAPLCORU_S_100 and PAI in EXIT_SAPLCORU_S_101.......or .........Can any tel me what should i have to do to
meet the requirements... and in which structure i have to add this field so that it gets stored in some table.
Thanks in Advance.

Hi,
Use the includes in the program SAPLXCOF given in CONFPP07 Exit.
You may use include zxcofzzz ( for Subprograms and Modules )
by creating it upon double click.

Looking for sample code using "first_tab" and "next_tab"

Looking for sample code using "first_tab" and "next_tab". How is it used with ItemID within a dialog box? I've read the reference books - don't understand it.

Hi Ray,
There are several ways to do this, and in the example I created, I actually did not end up using shift registers. I've attached some example code that basically multiplies the period by the duty cycle percentage to achieve the number of milliseconds to be high and low.
You would just need to insert your DIO code in each frame of the sequence structure.
Hope that helps. Kind regards,

Process PBO and PAI when Enter key is pressed

Hello everyone,
I am making a program where there is a I/O Box component. When the user enters data in this field and hits the 'ENTER' key I want to process the PBO and the PAI of that screen.
The problem is what should i assign in the ok_code for this?
Please advise.
Thanks in advance,

You want to Go when user Press enter.
In PBO we will set the status,
SET PF-STATUS 'STATUS'. " double click on it or Go to SE41
here activate the Function code for the ENTER button.
in the FUnction keys you can see in the Beginning First Function (Green Tick mark) Give the Function code say ENTER , and give all necessary details and Activate .
Now Test your application.
When your enter the data and press enter, First it Goes to PAI
here you do what ever required based on the action code...
in PAI
case ok_code.
when 'ENTER'.
"your code here...
endcase.
and once it is done, Control backs to PBO ..

Additional field in infotype 0009 issue ( PBO and PAI )

Hi Guru,
I need your help please.
I have a additional field in IT0009 and when I want created a new infotype 0009, I fill all field but after ENTER or SAVE all field are save in the layout but not the additional field.
To save the additional field in the layout, I must fill it again and after the ENTER or SAVE the field is save in the layout.
I have checked in the debbugger, when I create a new infotype 0009 it goes to the PBO but after ENTER or SAVE it doesn't go to the PAI so I must do it again ( fill the additional field and ENTER or SAVE ) and then it goes to the PAI.
Thus I would like to know how I can make so that after the ENTER or SAVE the screen goes in PAI before the PBO and at the first time.
Thanks very much in advance.
Regards.

Hi Srini Vas, hi Pedro Guarita and thanks for your reply,
After more investigation, the probleme come from a check over country bank.
In fact, the screen of the infotype 0009 must be adpated following the country bank but to do this, the standard module pool (mp000900) check if the country bank have changed.
call method cl_hrpad00_iban=>process_iban_pai
      changing
        cs_bankdata = ls_bank_data_current
      exceptions
        error_iban = 1
        others      = 2.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
                 with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    endif.
    call method cl_hrpad00_iban=>get_bank_data_old
      importing
        bank_data_old = ls_bank_data_old.
    if ls_bank_data_current-banks <> ls_bank_data_old-banks. "MELN1357200
bank country changed -> leave screen needs to be done
      leave_screen = 'X'.
    endif.
But when you create a new infotype 0009, the ls_bank_data_old-banks is always initial. So when module pool compared the ls_bank_data_old-banks with the ls_bank_data_current-banks, those are always different.
In conclusion, when you create a new infotype 0009 it is always mandatory to push ENTER before to fill any additional field because at each first time that the standard module pool go in the PAI, it make a leave screen.
Thanks in advance for all yours reply.

Why is this happening?
Pls let me know whether this code works or no and also i have written form.html.

Cocode check at PBO and PAI

Hi
I should not allow Cocode AD01 records to update and Display when user has authorization for CoCode AD01.
i know in Event its possible, but we need to do it in PBO PAI of Screen.

Sample code to download and open an Asset

For anyone who wants to download an asset from the web and load it into your Adobe application, this is how I did it:
// .js
var TMP_FOLDER="/tmp/com.mb.extension/";
var doOpen = function(uri) {
          var xhr = new XMLHttpRequest();
          xhr.open("GET", uri, true);
          xhr.responseType = "blob";
          xhr.onload = function(event) {
                    var blob = this.response;
                    var data;
                    blobToBase64(blob, function(result) {
                              data = result;
                              var file = TMP_FOLDER+name;
                              window.cep.fs.writeFile(file, data, cep.encoding.Base64);
                              doOpenFile(file);
          xhr.send();
function doOpenFile(file) {
          var ppid = "ILST";
          var extScript = "$._ext_"+ppid+".open('"+file+"')";
          evalScript(extScript);
var base64ToBlob = function(base64, callback) {
var binary = atob(base64);
var len = binary.length;
var buffer = new ArrayBuffer(len);
var view = new Uint8Array(buffer);
for (var i = 0; i < len; i++) {
       view[i] = binary.charCodeAt(i);
callback(new Blob([view]));
// .jsx
$._ext_ILST={
    open : function(path) {
        openDocument(path);
var openDocument = function(path) {
    return app.open(File(path));

I don't know why, but when I use this code. The file was downloaded right, but Illustrator doesn't open the file.
When doOpenFile is fired the args are correct, because I have debug it in console. But I think the problem is with the JSX file, sure I'm doing something wrong.
Anybody could guide me about it?
I'm newbie trying to script Adobe Extensions.

Where I could find the sample code for Pan and Zoom?

hello all:
I saw a demo for showing how to implement Pan and Zoom in java. If I remember correctly it should be included in JAI, however I cannot find it in JAI sample demos any more.
THe only samples it included are
* JAIDemo
* JAIExampleApp/SampleDescriptor
* JAIFileBrowser
* JAIWarpDemo
* JAIImageReader
* FormatDemo
Does anyone know where I could find that demo back?
Thank you
