Help With Choosing The Technology

Hello,
I need help in choosing the appropriate technology for the application that I'm going to be creating.
The characteristics of the system that have been decided until now:
Standalone app built on either Flex/Flash/AIR
Restricted to using the system on a single computer, hence can be a tightly coupled system
The server component of the system needs to be closed source and robust, for which im thinking something like a Java backend,etc,etc.
In a completely new environment, all that i need to be able to do is install just the AIR application and not worry about installing extra stuff for the server support.
Thanks In Advance for anyone who can help me out with this.

If you are saying you want the server component to be on the same machine as the Flex app, then your choices are severely limited due to the sandbox, unless of course you are using AIR, then you can just use the SQLite database.
But if there will be a sevrer component on another machine on the web, you could use BlazeDS, and like I said, its free and very robust.

HELP! Without any prompting for such a download, Firefox tells me 'Thank You for choosing Firefox 4', & I have lost ALL of my bookmarks! I absolutely need to restore them, please please help. Not impressed at all!

I am shellshocked.... so far I am not happy with Firefox's latest effort. When I first got this version, my 'saved tabs' function did not work, which I use regularly, and I lost vital site information with the update. I figured out how to fix this by changing a setting, and figured my problems were over.
But NOW without any prompting from me, Firefox re-opened, having lost the tabs I had, yet again, and instead opened up two new tabs, 'Welcome to FireFox' (ty for choosing firefox4), and 'Mozilla Firefox Start Page', AND I have lost all my bookmarks!, WTF! Please help me to restore them, I have tried the help info provided, but they are still not restored :( Some of those treasured bookmarks, an extensive list, I will never get again, unless I can restore the ones I had. :( NOT IMPRESSED AT ALL.

Ok this is bizzare!
Thank you for your response, I went throught each and every step without any luck, even got the recovery programme, and painstakingly tried to sift through all that mumbojumbo to find what i needed. finally found the bookmark bit, but it had been fully overwritten :(, so on reading about previous ff versions, found the sqlite thingys, and they were relatively unscathed(partly written over, but saveable apparently TG), saved them to adiff drive, amongst other possibly good folders. Then looked up how to install them, and it said to close FF, and install to profile folder.
So i tried to close FF, and the original problem from a few days ago, where it asked me if 'i was sure i wanted to close this window as it has X tabs open', popped up again. This is where 'open blank page' selection was set, over 'open previous tabs'. Wanting to save that info on how to sort out these friggin files, I reset the Option to 'open previous tabs', and closed FF. After unsucessfully searching for the profile folder on my laptop, i opened FF intending to search online for where i could find said folder.
AND BANG, surprise surprise, the FF I had just closed with only tabs open about finding out what the heck to do, had disappeared, and instead my original saved tabs were up, and my bookmarks are there..... I am gobsmacked! what the heck just happened there???
I have made 3 back up in different folders now, of those friggin bookmarks. I am weary now tho of shutting it all down.... what if its back to the other pages I had with no bookmarks, tomorrow :(

Need suggestion for choosing Java development enviroment

Hi Evereyone,
I am new to Java Desktop Application.I need help on choosing proper Java technologies and development tool.
We have an existing CLIENT/SERVER based distributed control system, which was developed in C++(Server side) and VB(Client GUI).Now we are think of migrating the system to Java platform.
Here is the outline:
We want to create web based application that will run on windows and linux (linux on embedded PC).
The application should be able to support 10 � 100 users at once accessing/editing database.
We will also need to create a communication server that will run on web server P.C. that will communicate tcpip to field panels/log to db, as well as allow web screens to send/receive commands with field panels etc.
Could any one give me some suggestion about it?
I am thinking of Using J2SE 5.0, including RMI, JDBC and Swing for GUI. As for field panels, may choose J2ME.
Thank you very much in advance.

Thanks, zadok .
Actually, I don't have the system requirements neither. All I know is the following outline:
"We want to create web based application that will run on windows and linux (linux on embedded PC).
The application should be able to support 10 � 100 users at once accessing/editing database.
We will also need to create a communication server that will run on web server P.C. that will communicate tcpip to field panels/log to db, as well as allow web screens to send/receive commands with field panels etc."
It is a interview question, which need me to do research and give some suggestions. What I want to know is to figure out what kind of Java technology is necessary for developing this system because I want to make sure I head to right direction.
I know somehow it is hard to give suggestion based on this limited information.
One more thing I was confusing is the server-side architecture.
I need suggestion about sever side architecture:
a. write a dedicated server-side program, which act
as communication server to monitor and control field
panel, also act as server-side applicaiton by using
RMI to communicate with Client-side communication.
b. choose a general web server architecture. Put
everything in server side in Web Server, for example
Tomcat AS container, implementing the Communication
server as Web Service and the request from
Client-side go to Web Server first, then dispatch to
a proper web service.Why did you not include this information in the original question!
Why don't you just use Tomcat?
For your answer, "Why don't you just use Tomcat?", does it mean Tomcat without Web Service will be enough for this system development? Could you give me some detail about it?
Thank you very much, zadok.

Creating search help for a field in AdHoc Query

Hi
We have created an infoset based on LDB PCH.
(The infoset contains object type O only).
For the object-id field the users want search help when choosing this field for selection.
Using "start via selection screen" does not give a good solution.
Can anyone explain how I can create search help for fields in an infoset?

Search Help for Vendor Feild not getting populated in the Screen Element

Hi Everyone,
In transaction Miro, I get a POP-UP for Invoicing Party i.e. Vendor and Users required a custom search help.
The Search help for Vendor(LIFNR) is KRED_C and i appended a Z search help under this.
Now that the search help exists and I can drill down the values too but when i select/choose any value, that value is not getting populated in Screen feild.
is there any validation I need to do for this.
Please suggest me... I checked SDN there are many things but i couldn't figure out wat i need to do and where I need to modify.

Dear Hema,
Could you please tell me how many internal tables you are using to store the data for display.
I observerd that you have lt_stock and lt_mat2 declared in the part of the program
>DATA: lv_stock TYPE lty_stock.
>DATA: ltmat2 TYPE TABLE OF lty_mat.
you have displayed above, however you are also using ls_stock and lv_stock .
>IF p_ztotal = ' '. "line
>WRITE 18 ls_stock-matnr.
>WRITE 38 lv_stock-strgr.
>
>ELSEIF ztotal = 'S'.                             "subtotal
    >WRITE: 15 ls_stock-nrmit.
    >WRITE 32 lv_stock-dispo.
    >WRITE 43 lv_stock-fevor.
>ELSE.                                            "total
    >WRITE: 15 'TOTAL'(016), ls_stock-prgrp.
>
>ENDIF.
Are those for displaying some other information?
Also the problem of display you are facing can also be because there are no records to be displayed which satisfies the selection criteria.
Best Regards,
Rajesh.

Where can I find detailed, systematic HELP for advanced topics relating to Thunderbird?

In moving from XP to Windows 7, I opted for Thunderbird as email client in order to bypass Microsoft's hyper-intrusive Windows Live Mail (I used Outlook Express for years).
I have a very complicated email structure, and it's taken me weeks (seriously) to learn how to replicate it in TBird. Now I'm trying to customize TBird further, but none of the TBird articles/forum Q&A's/Google searches address my questions.
There is no live tech support for TBird, and I'm just about ready to leave it for good. However -- one last effort: where can I find detailed, systematic HELP for advanced topics relating to Thunderbird?
Thanks.

I am no expert, but I don't know of any authoritative reference as to what elements of HTML and CSS are supported in Thunderbird. However, as I believe you appreciate, it's more than just what Thunderbird supports, but one must also think about what is likely to work in other email clients. Keep it simple. Avoid ancient deprecated tags that other email clients may not support, and for similar reasons, avoid cutting edge technology. Remember that recipients using tablets or smartphones won't appreciate large fancy email documents.
The only thing ''guaranteed'' to work in email is plain text. ;-)
If you haven't already discovered it, the Stationery add-on is designed specifically to support OE stationery in Thunderbird. Your existing stationery may "just work" in this add-on. It makes switching between various stationery templates much easier, but I'm not confident that it will affect interpretation of your CSS or HTML coding.
Your code is at least clean and minimal. Most times my involvement with troublesome templates and signatures centres on the horrible bloat and mso custom code generated by Word or Outlook.
Having said that, you and I are mortal enemies, as I don't have much patience with what you aspire to achieve. I specifically don't like background images, nor being obliged to suffer other folks' bizarre choice of typefaces and colours (but your simple 12pt black Tahoma is quite inoffensive. ;-) ) I'm of an age where my tolerance and eyesight are easily offended.
Nonetheless, I'm intrigued by how to parse the tag for the background image, as it doesn't look like a legitimate pathname to a graphics file. Does the background image actually appear as required?

Can you use a single webhelp file to display different help for two apps?

I have updated a WebHelp project for a Windows app (let’s call it App1). Now the Dev team is creating a separately installed app (lets call it App2) that shares some of the same Help information as the original app. Both apps can be installed on the same system. The Help for App1 is accessed from an About menu in the app UI. Some of the topics are dialog boxes accessed from a question mark icon (?) at the bottom of the UI (I assume map IDs are involved in hooking up the dialog box Help - I need to verify this with Dev). The Help for App2 will be accessed from the App2 UI, which looks very similar to the App1 UI, except that certain features in App1 are missing from App2.
Here are the parameters:
In some cases, entire Help topics will apply to both apps.
In some cases, a portion of a topic for App1 will also apply to App2.
In some cases, a topic or topic portion for App 1 does not apply to App2 and vice versa
I’m using Robohelp 9 (RH9). Is there a way to allow App1 to display only the WebHelp that is relevant to that app and for App2 to display only the WebHelp that is relevant to that app? Is there a solution that would allow me to use one Help project and build only one Help file, with the result that App 1 displays only the Help it needs and App 2 displays only the Help it needs? Would conditionalizing the Help and providing two sets of WebHelp be the solution? Or is there some other alternative?

You could do it in a couple of ways – one way is to have 1 project & use conditions to generate 2 flavours of WebHelp output, one for each App; the other way would be to use one project and create DUCC flavoured WebHelp – that way the use would choose to read the appropriate flavour of help for their App.

Help me choose a Macbook Pro

Hey everyone, I need some help in choosing which Macbook Pro is right for me.
Basically I'm wondering which of these 2 would be a better choice.
http://store.apple.com/us/product/FB471LL/A?mco=MTEzMjIzODU
http://store.apple.com/us/product/FB471LL/A?mco=MTEzMjIzODU
What are the main differences?
4gb of ram should be sufficient and I doubt I would ever upgrade to 8gb.
as for graphics, I would mostly only need a mac that would allow me to play the latest Sims games. the first has a graphics memory of 512 and the second has 256.
Thanks in advance.

sorry these are the 2 macs im looking at.
Now what do you guys think...?

Help me choose a 865PE board

Hi,
I need some help in choosing the best(most feature packed, fast etc.) MSI 865PE motherboard.
There are two boards that are pretty identical and trying to find the difference between them has been difficult. They are the Neo2-FIS2R and Neo2-PFISR.
Which one of these two should I buy? They cost about the same. What are the major differences between them?
Please help me in choosing.
Thanks!

Great, I did see this link earlier but I'm confused by several things and please excuse my ignorance but I have been out of the Hardware scene for 4-5 months which is a long time in hight tech.
First thing on this table that I see on the P version is "P4EE Support" what is this? and why does the first table not support it?
On the first table it had a column "PCB Ver." what is this and where can it be found on my computer or Mobo?
So from looking at this link then I can safely say that I can buy a prescott CPU and it will run fine on my neo2 FIS2R?
faster Prescott's, so are there variations in the CPU and will my board be able to handle the faster ones?
Sorry about all the questions but if I can get answers to these then it would be extremely helpful.

UPDATED:
I do find these two tables very confusing and there is little explanation, To me the first table is saying that all the boards only support P4's and not prescott? the second table is saying that only the Extreme Edition supports prescott?
but the second table also lists the FIS2R etc so its all very confusing????

2.do we want to create a MODULE PROCESS ON VALUE REQUEST ?
PLS tell me how to set search for the I/O field in se80?pls tell me the process?
i want to set the search help for more I/O fields in se80 but all the fields belongs to the same table?
can i create a single search for all these fields and use that for all the I/O fields ?
elementary search help or collective search help?
thanks & regards in advance,

Hi,
Input Help on the Screen
Within the Screen Painter, you can define two types of input help:
1. The FIELD statement with one of the additions VALUES or SELECT.
2. Linking a search help directly to a screen field.
If you link a search help directly to a screen field, it overrides the additions of the FIELD
statement. However, the input check [Page 581] functions of the FIELD statement remain
unaffected.
Input Help in Flow Logic
The following input help methods are obsolete and should not be used. They are still supported
for compatibility reasons.
In the screen flow logic, you can specify a value list for a screen field <f> as follows:
FIELD <f> VALUES (<val1>, <val2>,...).
The value list contains a series of single values <vali>. The NOT and BETWEEN additions for the
input check [Page 581] are not appropriate for input help.
You can also create a value list by accessing a database table as follows:
FIELD <f> SELECT *
FROM <dbtab>
WHERE <k1> = <f1> AND <k2> = <f2> AND...
In the WHERE condition, the fields of the primary key <ki> of the database table <dbtab> are
checked against the screen fields <fi>. The WHENEVER addition, used with input checks [Page
581], is not necessary for input help.
If you have used a ABAP Dictionary reference for field <f>, the selection and the hit list formatting
may be affected by any check table attached to the field.
Attaching a Search Help
Search helps from the ABAP Dictionary can be attached to a screen field [Ext.]. To do this, enter
the name of the search help in the corresponding field in the attributes of the screen field in the
Screen Painter. This assigns the first parameter of the search help to the screen field. It is only
possible to place a value from the hit list onto the screen.
Input help on a screen.

DATA: CARRIER(3) TYPE C,
CONNECTION(4) TYPE C.
CALL SCREEN 100.
MODULE CANCEL INPUT.
LEAVE PROGRAM.
ENDMODULE.
The next screen (statically defined) for screen 100 is itself. It has the following layout:
602 April 2001
Cancel
Airline
Flight number
Screen field with search help
Input help in the flow logic
The input fields have been adopted from the program fields CARRIER and
CONNECTION. The function code of the pushbutton is CANCEL, with function type
E. The search help DEMO_F4_DE with the search help parameter CARRID is
assigned to the screen field CARRIER. The search help uses the database table
SCARR.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
FIELD CARRIER VALUES ('AA', 'LH').
FIELD CONNECTION SELECT *
FROM SPFLI
WHERE CARRID = CARRIER
AND CONNID = CONNECTION.
When the user chooses the input help for the individual fields, the following input
help is displayed:
For the Airline field, the search help displays the names of the airlines and places the airline
code in the input field for the chosen line. If the airline code is not one of those listed in the
VALUES list of the screen flow logic, the input check triggers an error message in the PAI
event. So the search help overrides the VALUES addition for the input help, but not for the
input checks. This is therefore not an appropriate place to use the VALUE addition.
For the Flight number field, the flow logic displays the selected entries from the database
table SPFLI and places the selected line in the input field.

How to provide F4 help for a field in table control

Hi Friends,
I have requirement like below.
1.Create one custom transaction code with header and item information.
2.In item level, we will be designed table control to enter/display the data.
3.Table controls first field will be material number and next DOT number (Material may have many DOT numbers) and so on.
4.First user will enter material number in the table controls first rows first field and go to DOT number field.
5.DOT number has drop down option. If user selects drop down box of DOT number, he gets all the DOT numbers available in database. User selects one DOT number and double clicks on it then it will be populated in DOT number field box.
But for point number 5, business wants like when ever user enters material number in table control first field then select DOT numbers drop down then they want to see the particular materials DOT numbers only in the drop down list for selection. Not all DOT numbers available in data base. Same thing should happen for all item lines in table control.
Please see below example.
Assume data base table has 10 DOT numbers. But material number has only 2 DOT numbers. When ever user enters material number in item level table control and selects DOT numbers drop down then it should show only 2 DOT numbers which are related to particular material number. Not all 10 DOT numbers.
Could you please suggest me, how can we achieve this?

Hello,
Check this :-
For POV
Input Help in Dialog Modules
You can call dialog modules in the POV event using the event keyword PROCESS ON VALUE-REQUEST.
PROCESS ON VALUE-REQUEST.
FIELD <f> MODULE <mod>.
After the PROCESS ON VALUE-REQUEST statement, you can only use the MODULE statement together with the FIELD statement. When the user chooses F4 for a field <f>, the system calls the module <mod> belonging to the FIELD <f> statement. If there is more than one FIELD statement for the same field <f>, only the first is executed. The module <mod> is defined in the ABAP program like a normal PAI module. However, the contents of the screen field <f> are not available, since it is not transported by the FIELD statement during the PROCESS ON HELP-REQUEST event. You can now program your own value lists in the module. However, this procedure is only recommended if it really is not possible to use a search help. Defining search helps is much easier than PROCESS ON VALUE-REQUEST, since the system takes over some of the standard operations, such as getting field contents from the screen. It also ensures that the F4 help has a uniform look and feel throughout the system. Furthermore, it means that you do not have to reassign input help to fields on each screen.
Despite the introduction of search helps (and search help exits), there are still cases in which you need to use parts of the standard F4 functions directly. In this case, there are some standard function modules that you can use in the POV event. They support search helps, as well as all other kinds of input help, and are responsible for data transport between the screen and the input help. These all have the prefix F4IF_. The most important are:
F4IF_FIELD_VALUE_REQUEST
Calls the input help of the ABAP Dictionary dynamically. You can pass the component names of a structure or database table of the ABAP Dictionary to the function module in the import parameters TABNAME and FIELDNAME. The function module starts the ABAP Dictionary input help for this component. All of the relevant screen fields are read. If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the users 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.
F4IF_INT_TABLE_VALUE_REQUEST
This function module displays a value list that you created in an ABAP program. The value list is passed to the function module as the table parameter VALUE_TAB. If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the users 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.
There are also two function modules - DYNP_VALUES_READ and DYNP_VALUES_UPDATE - that can read the values of screen fields and return values to them during the POV event. For further information, refer to the relevant function module documentation.

MODULE INIT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
PROCESS ON VALUE-REQUEST.
FIELD CARRIER MODULE VALUE_CARRIER.
FIELD CONNECTION MODULE VALUE_CONNECTION.
When the user chooses input help for the individual fields, the following is displayed:
For the Airline field, the POV module VALUE_CARRIER is called. The function module F4IF_FIELD_VALUE_REQUEST displays the input help for the component CARRIER1 of the structure DEMOF4HELP from the ABAP Dictionary, namely the search help DEMOF4DE. The users selection is returned to the screen field CARRIER.
For the Flight number field, the POV module VALUE_CONNECTION is called. The function module DYNP_VALUE_READ transports the value of the screen field CARRIER into the program. The program then reads the corresponding values from the database table SPFLI into the internal table VALUES_TAB using a SELECT statement, and passes the internal table to F4IF_INT_TABLE_VALUE_REQUEST. This displays the internal table as input help, and places the users selection into the screen field CONNECTION.
For POH------------
Field Help
There are three ways of displaying field help for screen elements:
Data Element Documentation
If you place a field on the screen in the Screen Painter by copying a ABAP Dictionary field, the corresponding data element documentation from the ABAP Dictionary is automatically displayed when the user chooses field help (as long as the help has not been overridden in the screen flow logic).
For further information about creating data element documentation, refer to data elements.
Data Element Supplement Documentation
If the data element documentation is insufficient, you can expand it by writing a data element supplement
Data element supplement documentation contains the heading Definition, as well as the following others:
Use
Procedure
Examples
Dependencies
To create data element supplement documentation for a screen, choose Goto ® Documentation ® DE supplement doc. from the element list of the screen. A dialog box appears in which the system proposes a number as the identified for the data element supplement. You can then enter help texts for the above headings using the SAPscript editor.
Data element supplement documentation created in this way is program- and screen-specific. Any data element supplement documentation created in the ABAP Dictionary with the same number is overridden by the screen-specific documentation. You can link existing data element supplement documentation created in the ABAP Dictionary with a screen field by using the table THLPF. To do this, crate a new row in THLPF containing the following data: Program name, screen name, field name, and number of the data element supplement documentation.
To display data element supplement documentation, you must code the following screen flow logic in the POH event:
PROCESS ON HELP-REQUEST.
FIELD <f> [MODULE <mod>] WITH <num>.
After PROCESS ON HELP-REQUEST, you can only use FIELD statements. If there is no PROCESS ON HELP-REQUEST keyword in the flow logic of the screen, the data element documentation for the current field, or no help at all is displayed when the user chooses F1. Otherwise, the next FIELD statement containing the current field <f> is executed.
If there is screen-specific data element supplement documentation for the field <f>, you can display it by specifying its number <num>. The number <num> can be a literal or a variable. The variable must be declared and filled in the corresponding ABAP program.
You can fill the variables, for example, by calling the module <mod> before the help is displayed. However, the FIELD statement does not transport the contents of the screen field <f> to the ABAP program in the PROCESS ON HELP-REQUEST event.
For further information about data element supplement documentation, refer to Data Element Supplements.
Calling Help Texts from Dialog Modules
If data element supplement documentation is insufficient for your requirements, or you want to display help for program fields that you have not copied from the ABAP Dictionary, you can call dialog modules in the POH event:
PROCESS ON HELP-REQUEST.
FIELD <f> MODULE <mod>.
After the PROCESS ON HELP-REQUEST statement, you can only use the MODULE statement together with the FIELD statement. When the user chooses F1 for a field <f>, the system calls the module <mod> belonging to the FIELD <f> statement. If there is more than one FIELD statement for the same field <f>, only the first is executed. However, the contents of the screen field <f> are not available in the module <mod>, since it is not transported by the FIELD statement during the PROCESS ON HELP-REQUEST event. The field help should not be dependent on the user input.
The module <mod> is defined in the ABAP program like a normal PAI module. The processing logic of the module must ensure that adequate help is displayed for the field in question. Instead of calling an extra screen with text fields, you should use one of the following function modules to display a suitable SAPscript document:
HELP_OBJECT_SHOW_FOR_FIELD
This function module displays the data element documentation for components of any structure or database table from the ABAP Dictionary. You pass the name of the component and structure or table to the import parameters FIELD and TABLE.
HELP_OBJECT_SHOW
Use this function module to display any SAPscript document. You must pass the document class (for example, TX for general texts, DE for data element documentation) and the name of the document to the import parameters DOKCLASS and DOKNAME. For technical reasons, you must also pass an empty internal table with the line type TLINE to the tables parameter of the function module.
For further information about how to create SAPscript documents, refer to the Documentation of System Objects documentation.

The next screen (statically defined) for screen 100 is 100. It has the following layout:
The screen fields DEMOf1HELP-FIELD1 and DEMOF1HELP-FIELD2 from the ABAP Dictionary and the program fields FIELD3 and FIELD4 are assigned to the input fields. The pushbutton has the function code CANCEL with function type E.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
PROCESS ON HELP-REQUEST.
FIELD DEMOF1HELP-FIELD2 MODULE F1_HELP_FIELD2 WITH VAR.
FIELD FIELD3 MODULE F1_HELP_FIELD3.
FIELD FIELD4 MODULE F1_HELP_FIELD4.
The components FIELD1 and FIELD2 of structure DEMOF1HELP both refer to the data element DEMOF1TYPE. This data element is documented, and also has two supplements with numbers 0100 and 0200.
The following field help is displayed:
When the user chooses F1 on the input field for DEMOF1HELP-FIELD1, the data element documentation for DEMOF1TYPE is displayed, since the field does not occur in the PROCESS ON HELP-REQUEST event.
If the user chooses F1 repeatedly for the input field DEMOF1HELP-FIELD2, the data element documentation is displayed, along with the supplement documentation for either 0100 or 0200 alternately. The variable VAR is filled in the dialog module F1_HELP_FIELD2.
When the user chooses F1 on the input field for FIELD3, the data element documentation for DEMOF1TYPE is displayed, since this is called in the dialog module F1_HELP_FIELD3 by the function module HELP_OBJECT_SHOW_FOR_FIELD.
When the user chooses F1 on the input field for FIELD4, the SAPscript documentation DEMO_FOR_F1_HELP is displayed, since this is called in the dialog module F1_HELP_FIELD4 by the function module HELP_OBJECT.
