Acrobat javascript global variable

what is the step by step procedure on how to define your global variable and where to declare it?

You can create a global variable anytime you want, so when you do it really depends on when and where it needs to be accessible. If you provide more details about how you intend to use it, we can provide more guidance. Here's the basics:

http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.774.html
The other important issue is whether it needs to be stored so it can be accessed the next time Acrobat is started. That's what the global.setPersistent method is for: http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.778.html

Javascript array in global variables

Hi,
In my form, I created a global variable called MyArray. Then in my form's initialization script, I've set:
myform.variables.MyArray = new Array(5);
and I initialized each value.
In one of my button's click event, I try to access my global array, without success. I tried:
myform.variables.MyArray[0], myform.variables.MyArray.value[0]... has anyone managed to create a global variable and use it as an array?
Thank you!

Hello.
I have used the "global." to get global variables. It works fine. I have code like this that works:
// Initialize global array.
global.chVArray = new Array(4);
for (i = 1; i <= 4; i++){
global.chVArray[i] = false;
// Somewhere else...
for (i = 1; i <= 4; i++){
xfa.host.messageBox (global.chVArray[i].toString());

How to execute acrobat javascript thorugh acrobat plugin???

I need to perform a task using javascipt...but i am not able to run javascript from my plugin...I tried it using AFExecuteThisScript method given in API but it asks for " _gAcroFormHFT"..How can i import HFT into my plugin???
Is there any other method to execute a javascript from acrobat plugin??

You need to declare a (global) variable something like:
HFT gAcroFormHFT;
Then initialise it in your plugin's PluginImportReplaceAndRegister method, something like:
ACCB1 ASBool ACCB2 PluginImportReplaceAndRegister(void)
gAcroFormHFT = Init_AcroFormHFT;
return true;

Setting the value of an Application Item (setting a global variable);

In APEX 3.2.0.00.27, I need to initialize a global variable to 0 to implement a variable for testing to see if anything on the page has changed. Will update to 1 when certain select lists on the page are changed. Have read through some similar questions and replies within the forum as well as other blogs and sites. So, I believe what I am doing is the way to go about this. Unfortunately, my initialization of an application item/global isn't happening yet. here's a rundown of what has been implemented:
1) created an application item, G_CLASSIFICATION_ID_NEW in the shared components;
2) created Javascript (JS) function called by addLoadEvent in the page html header region so when the page loads, the G_CLASSIFICATION_ID_NEW global/application item should get set to 0 with the following JS and using AJAX and htmldb_GET:
<script type="text/javascript">
function initVars()
alert("before get initvars");
var get = new htmldb_Get(null,$x('pFlowId').value,null,22);
get.add('G_CLASSIFICATION_ID_NEW', 0);
gReturn = get.get();
if(gReturn){
alert(gReturn.value);
get = null;
alert("after get initvars");
alert("before call to initpage");
addLoadEvent(initVars());
</script>
I've used the htmldb_Get with success for populating other global variables and running On Demand Processes with onchange JS calls in the html form element attributes within select lists on the page. Afterwards, I can check the globals via the Session window and searching on Application Items. Unfortunately, I'm missing something because my G_CLASSIFICATION_ID_NEW never gets populated when I load the page. The alerts all popup when the page is loaded, so I know the script is being executed when the page loads. the alert(gReturn.value) comes back undefined. And, needless to say, the G_CLASSIFICATION_ID_NEW to 0 is not occurring.
I've tried the htmldb_Get with it calling an application process and without (set to null). From what I've read, you shouldn't need to call an on demand process to have the get.add set the global variable. Then again, this could be where I'm going wrong. however, as I've mentioned, this works for other functions called from an onchange to populate an application item, but the page has already loaded when the onchange(s) get executed. They may work because the page is already loaded when the onchange is called. My point here is that my other On demand processes are NOT setting or changing the global variables at all. The globals are getting set with the get.add(<app item>, <value>) portion of my other JS functions within the HTML Header region. So, I'm inclined to believe that I don't need the 'application_process=<some_odp>' parameter set, but if that's not true, please let me know. if so, what would need to be in the on demand process--ie, what would be the purpose of the get.add(<application item>, <value>) if I set the global variable in the on demand process because that's the only thing I could think of doing within an on demand process for this?
If somebody can point out what I'm not understanding or failing to do here, that would be great. I'm doing fine with APEX, but wouldn't consider myself a guru with it just yet. I'm definitely not a JS/AJAX guru, and when things like this go astray, I get bogged down because I'm not sure of the problem. So, I'm hoping you gurus who monitor this forum can get me going in the right direction.
thanks,

Hi Jari,
Does that javascript work if you place it some of region footer on page 22 ?Yes. I cut it out of the html header of the page, and put it in the footer of the first region on the page. It initializes the variable. Putting it into the footer of the first region on the page should work for me instead of having an extra region on the page that's being picked up from page 0.
Is your page 22 authentication public ?No. This particular page is set for an ADMINISTRATOR only. That said, I am logged in as an administrator. So, I cannot see why setting authentication should make a difference as long as I have that authentication/authorization. Also, there will be other pages where I want to use this script or a similar script, but again, those pages will not be open to the public. the authentication will be "role" based where a user will not necessarily have to be an administrator, but they will have to have a certain role to access the page. Is there a known problem or something that precludes a html header JS script from doing an addloadevent when authentication is NOT public?
thank you,
bob

Moment global variable values

In ISF/Javascript, what are all the values for the Moment global variable?
For example, (Moment == "ordering") can be used to check if the current moment is Ordering moment. What are the values for all other moments, specifically Service Group Review and Service Group Authorization moments?
Thank you.

The values for Service Group Review moment is "streviews" and Service Group Authorization moment is "stauthorizations".
You are correct that these are not in the designer documentation. One way you can find them is through view page or frame HTML source when the service form is in that particular moment, and look for the word "Moment".

Using a global variable within a function

Hi all,
I'm trying to learn how to use global variables, but can't quite get it right:
Im trying to use two buttons, named UpButton and DownButton to control one global variable, p1
A text field, named "Value" displays p1.
Here's my code:
p1 = 0;
ButtonClick("UpButton", p1, 100,"Value");
ButtonClick("DownButton", p1,(-100),"Value");
function ButtonClick(ButtonName,Var,Increment,TextToChange){
                    sym.$(ButtonName).click(function(){
                    Var = Var + Increment;
                    sym.$(TextToChange).html(Var);
However, it seems to be treating p1 as two different variables.
Here's a link to the page to show you what I mean, apologies but this link wont work in google chrome because I'm using dropbox as a server temporarily
In other browsers you may need to click "Show all content" or similar to any security warnings...
https://dl.dropboxusercontent.com/u/83693404/ButtonTest/buttons.html
Here are the project files:

Any help greatly appreciated, sorry if this is a stupid question,
Katherine

Hi Katherine,
However, it seems to be treating p1 as two different variables.
Indeed, your code created two different variables in two different scopes (I guess it as to do with JavaScript closures, but do not ask me more, I am still a bit foggy about that idiosyncrasy ).
In JavaScript, a primitive parameter – this is the case here with p1, a Number value –, is passed by value. In other words, a copy of the value is made. Your code handles two copies of the value stored in p1.
This contrasts with an object parameter, which is passed by reference (address in memory), without copy. Your code would work if Numbers were passed by reference : the two Var (p1) would then point to the same address.
The intent behind your trial is a global variable.
1) Let us be as simple as possible :
Stage : document.compositionReady event handler
p1 = 0;
buttonClick = function( Increment)
p1 += Increment;
sym.$( "Value").html( p1);
Stage : DownButton.click event handler
buttonClick(-100);
Stage : UpButton.click event handler
buttonClick(100);
Without being preceded by the var keyword the variables are global.
So the Number variable p1 can be accessed inside function buttonClick.
And the Function variable buttonClick as well, is accessible inside click event handlers, everything (function definition +function calls) being inside the same symbol (Stage).
2) Now, suppose this is no longer the case : you want to access a variable from another symbol.
We create a new GraySquare symbol, instantiated both in the DownButton symbol (instance name DownSquare) and in the UpButton symbol (instance name DownSquare).
Stage : document.compositionReady event handler
p1 = 0;
sym.buttonClick = function( Increment)
p1 += Increment;
sym.$( "Value").html( p1);
The sym. prefix is now necessary to make the variable (here a Function, but you would proceed exactly the same with a String, Number or Boolean) accessible in other symbols.
DownButton symbol : DownSquare.click event handler
sym.getComposition().getStage().buttonClick( -100);
UpButton symbol : UpSquare.click event handler
sym.getComposition().getStage().buttonClick( 100);
From these other symbols, the sym.getComposition().getStage(). prefix is necessary to acces to our global variable (function).
The two examples are downloadable here : https://app.box.com/s/6vkyiqk7i8zwlw0j1wk1

Acrobat Javascript button not loading when PDF is opened in browser

We have a requirement to have a custom print button in Acrobat Reader 9.1.3. We've created this via a JavaScript file stored in the users application data Adobe javascript folder. The button appears when Acrobat is started up normally and works as expected. However when opening a pdf file via Internet Explorer 7 acrobat is loaded inside the browser but the button does not appear automatically. Instead we need to right click on the tool bar and select Add on tools for the button to appear. Once loaded it works as expected.
Now I was wondering is there a way to make the button to appear automatically when acrobat is launched from within IE as my users are getting a bit annoyed now. I've been searching all over the place and can't find a solution to this.
Am hoping someone here might have an idea as to what the problem might be. I've attached the code I'm using below.
Thanks in advance
app.addToolButton({
cName: "myToolButton",
cExec: "printGreen()",
cEnable: true,
cTooltext: "Print to Green",
cLabel: "Print to Green"
global.objDoc = this;
printGreen = app.trustedFunction (
function()
app.beginPriv();
var objPrintParams = this.getPrintParams();
objPrintParams.printerName = "\\\\burns\\prn-cash-copier";
objPrintParams.interactive = objPrintParams.constants.interactionLevel.automatic;
this.print(objPrintParams);
app.endPriv();

OK... I'm still puzzled. There seems to be something else that controls whether Acrobat JavaScript runs or not.
If I'm loading a pdf stream though a http GET, JavaScript in Acrobat is run even when the setting in Edit->Preferences is disabled.
<body>
<iframe height=600 width=400 src = "http://<some servlet that returns a pdf stream>" />
</body>
If I'm loading the pdf from a file...
<body>
<iframe height=600 width=400 src = "<pdf file path>" />
</body>
... the expected warning (that Adobe javascript is disabled) pops up
The http response in the first case is something like...
HTTP/1.1 200 OK

Loading defining global variables?

Hello all!
I have a project that is an online presentation, which I (being no pro in codeing) create in Edge and Muse. I create the animation in Edge, publish it as OAM and place it into the muse site/page. Master looks fine and I am happy with it.
My problem, that I have to solve, is that it has to be translated into 44 Languages and kept updated regularly, which is near to impossible without using external data source.
I thought to create an XML file for each language and use it for text and maybe Image content. I can use an xml file for a specific animation, but at my current knowledge level i!Il have to define the variables and the source of content for each and every animation/object.
What I would like to see is that if you land on the Index page, you can choose the preferred language, and all the content appeares in the given language. For that (my best guess) I'll have to define global variables, which do not lose their value i.e.: which is my preferred language.
How do I do that? Had anyone a similar issue? Also, how do I use external data in Muse?
Any help would be appreciated!

Here it is :
In the Stage > document.compositionReady event handler, we define a JavaScript object LANG containing
• a property flag that is the state of the displayed flag (in the example file, symbol drapeau, french for flag) ;
• a function switchLang executed each time the flag is clicked, to refresh the content of
- the three titles (b1A_tit, b1B_tit, b1C_tit) by assigning hard-coded values,
- the three texts (b1A_txt, b1B_txt, b1C_txt) by loading HTML snippets files in a text folder.
LANG =
flag: 'NL',
switchLang: function()
    sym.getSymbol('bandeauH').getSymbol('drapeau').stop( LANG.flag);
    var symBloc1A = sym.getSymbol("bloc1A");
    var symBloc1B = sym.getSymbol("bloc1B");
    var symBloc1C = sym.getSymbol("bloc1C");
    switch (LANG.flag)
      case 'NL':
        symBloc1A.$('b1A_tit').html("Montagne");
        symBloc1A.$('b1A_txt').load('text/b1A_FR.html');
        symBloc1B.$('b1B_tit').text("Peinture");
        symBloc1B.$('b1B_txt').load('text/b1B_FR.html');
        symBloc1C.$('b1C_tit').text("Maison d’hôtes");
        symBloc1C.$('b1C_txt').load('text/b1C_FR.html');
        LANG.flag = 'FR';
        break;
      case 'FR':
        symBloc1A.$("b1A_tit").text("Montagne");
        symBloc1A.$('b1A_txt').load('text/b1A_NL.html');
        symBloc1B.$("b1B_tit").text("Schilderen");
        symBloc1B.$('b1B_txt').load('text/b1B_NL.html');
        symBloc1C.$("b1C_tit").text("Bed & Breakfast");
        symBloc1C.$('b1C_txt').load('text/b1C_NL.html');
        LANG.flag = 'NL';
        break;
LANG.switchLang();
The drapeau > click event handler is a single call to LANG.switchLang();

Javascript discussion: Variable scopes and functions

Hi,
I'm wondering how people proceed regarding variable scope, and calling
functions and things. For instance, it's finally sunk in that almost
always a variable should be declared with var to keep it local.
But along similar lines, how should one deal with functions? That is,
should every function be completely self contained -- i.e. must any
variables outside the scope of the function be passed to the function,
and the function may not alter any variables but those that are local to
it? Or is that not necessary to be so strict?
Functions also seem to be limited in that they can only return a single
variable. But what if I want to create a function that alters a bunch of
variables?
So I guess that's two questions:
(1) Should all functions be self-contained?
(2) What if the function needs to return a whole bunch of variables?
Thanks,
Ariel

Ariel:
(Incidentally, I couldn't find any way of marking answers correct when I visited the web forums a few days ago, so I gave up.)
It's there...as long as you're logged in at least, and are the poster of the thread.
What I want is to write code that I can easily come back to a few months later
and make changes/add features -- so it's only me that sees the code, but
after long intervals it can almost be as though someone else has written
it! So I was wondering if I would be doing myself a favour by being more
strict about make functions independent etc. Also, I was noticing that
in the sample scripts that accompany InDesign (written by Olav Kvern?)
the functions seem always to require all variables to be passed to it.
Where it is not impractical to do so, you should make functions independent and reusable. But there are plenty of cases where it is impractical, or at least very annoying to do so.
The sample scripts for InDesign are written to be in parallel between three different languages, and have a certain lowest-common-denominator effect. They also make use of some practices I would consider Not Very Good. I would not recommend them as an example for how to learn to write a large Javascript project.
I'm not 100% sure what you mean by persistent session. Most of my
scripts are run once and then quit. However, some do create a modeless
dialog (ie where you can interface with the UI while running it), which
is the only time I need to use #targetengine.
Any script that specifies a #targetengine other than "main" is in a persistent session. It means that variables (and functions) will persist from script invokation to invokation. If you have two scripts that run in #targetengine session, for instance, because of their user interfaces, they can have conficting global variables. (Some people will suggest you should give each script its own #targetengine. I am not convinced this is a good idea, but my reasons against it are mostly speculation about performance and memory issues, which are things I will later tell you to not worry about.)
But I think you've answered one of my questions when you say that the
thing to avoid is the "v1" scope. Although I don't really see what the
problem is in the context of InDesign scripting (unless someone else is
going to using your script as function in one of theirs). Probably in
Web design it's more of an issue, because a web page could be running
several scripts at the same time?
It's more of an issue in web browsers, certainly (which I have ~no experience writing complex Javascript for, by the way), but it matters in ID, too. See above. It also complicates code reuse across projects.
Regarding functions altering variables: for example, I have a catalog
script. myMasterPage is a variable that keeps track of which masterpage
is being used. A function addPage() will add a page, but will need to
update myMasterPage because many other functions in the script refer to
that. However, addPage() also needs to update the total page count
variable, the database-line-number-index-variable and several others,
which are all used in most other functions. It seems laborious and
unnecessary to pass them all to each function, then have the function
alter them and return an array that would then need to be deciphered and
applied back to the main variables. So in such a case I let the function
alter these "global" (though not v1) variables. You're saying that's okay.
Yes, that is OK. It's not a good idea to call that scope "global," though, since you'll promote confusion. You could call it...outer function scope, maybe? Not sure; that assumes addPage() is nested within some other function whose scope is containing myMasterPage.
It is definitely true that you should not individually pass them to the function and return them as an array and reassign them to the outer function's variables.
I think it is OK for addPage() to change them, yes.
Another approach would be something like:
(function() {
var MPstate = {
    totalPages: 0,
    dbline: -1
function addPage(state) {
    state.totalPages++;
    state.dbline=0;
    return state;
MPstate = addPage(MPstate);
I don't think this is a particularly good approach, though. It is clunky and also doesn't permit an easy way for addPage() to return success or failure.
Of course it could instead do something like:
    return { success: true, state: state };
var returnVal = addPage(MPstate);
if (returnVal.success) { MPstate = returnVal.state; }
but that's not very comforting either. Letting addPage() access it's parent functions variables works much much better, as you surmised.
However, the down-side is that intuitively I feel this makes the script
more "messy" -- less legible and professional. (On the other hand, I
recall reading that passing a lot of variables to functions comes with a
performance penalty.)
I think that as long as you sufficiently clearly comment your code it is fine.
Remember this sort of thing is part-and-parcel for a language that has classes and method functions inside those classes (e.g. Java, Python, ActionScript3, C++, etc.). It's totally reasonable for a class to define a bunch of variables that are scoped to that class and then implement a bunch of methods to modify those class variables. You should not sweat it.
Passing lots of variables to functions does not incur any meaningful performance penalty at the level you should be worrying about. Premature optimization is almost always a bad idea. On the other hand, you should avoid doing so for a different reason -- it is hard to read and confusing to remember when the number of arguments to something is more than three or so. For instance, compare:
addPage("iv", 3, "The rain in spain", 4, loremIpsumText);
addPage({ name: "iv", insertAfter: 3, headingText: "The rain in spain",
numberColumns: 4, bodyText: loremIpsumText});
The latter is more verbose, but immensely more readable. And the order of parameters no longer matters.
You should, in general, use Objects in this way when the number of parameters exceeds about three.
I knew a function could return an array. I'll have to read up on it
returing an object. (I mean, I guess I intuitively knew that too -- I'm
sure I've had functions return textFrames or what-have-you),
Remember that in Javascript, when we say Object we mean something like an associative array or dictionary in other languages. An arbitrary set of name/value pairs. This is confusing because it also means other kinds of objects, like DOM objects (textFrames, etc.), which are technically Javascript Objects too, because everything inherits from Object.prototype. But...that's not what I mean.
So yes, read up on Objects. They are incredibly handy.

In short, I want the code within:

...to be able to access the variables I have created in:
----- form1.#subform[0]::initialize: - (FormCalc, client) ------------------------------------------
(I have assumed that this is where I would store Global variables)
At this stage, the global variables cannot be accessed with the configuration above. The only was I can get this to work is to cut and paste the global vairables into each form1.#subform[0] item, which of course defeats the purpose of global variables! I plan to have many more items so would not want to duplicate the global variables for all of them!
Can somebody show me how to do this?
Any help is very much appreciated!
Thanks

Hi MorisTM,
Thanks for the reply!
Yes, I saw that option (I should have mentioned I already knew about it), but was wondering if there is a way I can do this via code.
There are two reason I want to be able to do it via code (only one of which may be valid):
1) I can automatically generate my pricing code form another inhouse app.
2) I am hoping that later on once I get this working I will be able take it a step further and get the data directly from a MySQL database!
Cheers though!
Any other suggestions?

Use of global variables like g_cnt_transactions_transferred in the LSMW

Hi SapAll.
when i had a look at the some of the LSMW's whic use IDOC as the object of uploading data into SAP from external Files i have found in the coding under the step "Maintain Field Mapping and Conversion Rules" that they use some of the global variables like below
.if p_trfcpt = yes or sy-saprl >= '46A'.
EDI_DC40-DOCNUM = g_cnt_transactions_transferred + 1.
endif.
.EDI_DC40-CIMTYP = g_cimtyp.
.EDI_DC40-MESTYP = g_mestyp.
.EDI_DC40-MESCOD = g_mescod.
.if p_filept = yes.
EDI_DC40-SNDPOR = g_fileport.
elseif p_trfcpt = yes.
EDI_DC40-SNDPOR = g_trfcport.
endif.
my doubt is where i can find these variables 'g_cnt_transactions_transferred ','g_cimtyp','g_mescod','g_fileport','g_trfcport' in the LSMW and what is the use of the variable 'g_cnt_transactions_transferred ' in the LSMW.
I have treid to find out the above listed variables looking in step 'Maintain Field Mapping and Conversion Rules' under global variabels list and the other lists also but i couldnt found.
can any one help me in this ?
regards.
Seetha.

Hi Seetha,
In the LSMW Workbench go to the option user menu. And check the option display conversion program.
Now when you execute with the radio button on dislplay conversion program, you ll see the code that got generated in the background while you built your LSMW.
The global variables that you have mentioned are bound to be there in this program generated in the background..
You can put a break point here and see for yourself what the value of these global variables are at runtime.
File port, TRFC port , no. of transactions executed by one run of the LMSW Idoc program , message type are some of the fields that you have asked for .

Arun

Java Threads vs. Native Global Variables

A brief description of the problem:
I am trying to integrate a multi-threaded Java app with legacy Fortran code. The Fortran code in question makes extensive use of global variables in the form of Fortran's Common Block data structure.
If multiple threads were allowed access to a native routine, they would over write each others data which is stored in global variables.
If only one thread at a time can have access to the native routine for the duration of the native routine, the whole advantage of using threads is completely nullified.
These native routines cannot be rewritten (3rd party code) and must be used.
One solution I envisioned was to load a new copy of the native shared object code for each Java object that used the native code. However, it seems System.loadLibrary() can only be used in a static context.
Is there any known solution to this problem?

Here is an elaboration on the earlier suggestions. It's a high overhead solution, because you have to start a bunch of JVMs.
1. You have a java control program, which will start up a pool of "services", make requests to them, and gather the results.
2. Each service is a small java program with a native method:
o java communications front-end.
o native method declaration.
o native - in your case fortran - method implementation.
3. Each service is started using "exec". That puts it in a separate process.
4, Since each service is a java program, you can use java to do communications between the control program and the service.
o You could use RMI.
o You could - perhaps - use java Process communications, i.e., have the services write to stdout, and have the control program capture the output.
o You could use socket communications.

Unit Testing and APEX Global Variables

We've recently started to unit test our database level PL/SQL business logic.
As such we have a need to be able to simulate or provide output from PL/SQL APEX components in order to facilitate testing of these components.
Some of the most obvious portions that need simulation are:
1. The existence of a session
2. The current application ID
3. The current page ID.
We currently handle requirement #1 by using apex_040100.wwv_flow_session.create_new
We handle 2 and 3 using the apex_application.g_flow_id and g_flow_step_id global variables.
I'm just wondering, how safe is it for us to use wwv_flow_session.create_new to simulate the creation of a session at testing time for those things which need a session?
I've also noticed that there are apex_application.get_application_id and apex_application.get_page_id functions whose output is not tied to the global variables (at least in our current version).
Is it safe for us to expect that we can set these global variables for use in testing or is apex moving to get_application_id and get_page_id functions away from global variables?
Will there be corresponding set_application_id and set_page_id functions in the future?
Sorry for the question bomb. Thanks for any help.

My first question would be why do you need to establish a session to test your PL/SQL?
wwv_flow_session is a package internal to APEX, and you should probably leave it be.
The get_application_id procedure you refer to is in apex_application_install, which is used for scripting installation of applications - not get/set of page ID like you're describing.
If you're uncomfortable using apex_application.g_flow_id, you can use v('APP_ID') or preferably pass the app_id/page_id as parameters to your procedures.
Your question seems to have a few unknowns, so that's the best I can describe.

Can F4IF_INT_TABLE_VALUE_REQUEST FM return a value in a global variable?

Hi everybody,
I need to use F4IF_INT_TABLE_VALUE_REQUEST FM because I have to let users select an specific option before choosing another value. The point is that I need to save in a program global variable what the user selects, and decide something with it in the program.
Is it possible that F4IF_INT_TABLE_VALUE_REQUEST FM returns the value in a sinple variable or it has to be paramter?
I look in a lot of previous threads but I didn't find anything, and I don't know if it's possible.
Thanks and kind regards,
MMP.

Hi,
Sure you can. All you need to do is to store what the function returns in your global variable. It don't need to be returned back to screen field.
DATA: BEGIN OF VALUES OCCURS 0,
         CARRID TYPE SPFLI-CARRID,
         CONNID TYPE SPFLI-CONNID,
       END OF VALUES.
DATA: VALUES_TAB TYPE TABLE OF VALUES,
          G_VALUE TYPE SPFLI-CONNID. "global variable to store what is returned
"in PAI first populate your table
SELECT CARRID CONNID
    FROM SPFLI
    INTO CORRESPONDING FIELDS OF TABLE VALUES_TAB
    UP TO 10 ROWS.
"then call the function but don't return the value to screen field
"If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the useru2019s selection is
"returned to the corresponding field on the screen. If you specify the table parameter RETURN_TAB, the
"selection is returned into the table instead.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            RETFIELD         = 'CONNID'
            VALUE_ORG        = 'S'
       TABLES
            VALUE_TAB        = VALUES_TAB
            RETURN_TAB      = RETURN_TAB.
"now simply read first row of return tab and store the value returned there in some global var
READ RETURN_TAB INDEX 1.
MOVE RETURN_TAB-FIELDVAL TO G_VALUE.
