Usage of exits
Hi experts,
I would like to get some information on user exits. how to identify which user exit is in needed for what scenario.
USEREXIT_DELETE_DCUMENT //// USEREXIT_MOVE_FIELD_TO_VBAK /// USEREXIT_MOVE_FIELD_TO_VBKD....like this , I just want to know in what situation we use these exits , can anybody provide with a small examples.
And whats the purpose of CMOD Tcode to indetify user exit and adding code to the include? ( when we can use the above Mentioned userexits?) correct Me if i am wrong.
Thank you,
Kanna.

Usage Customer Exit EXIT_SAPLCUKO_003 / Enhancement CCUX0004
Hello,
I like to add new attributes of instances in LOVC during configuration of material in VA02. I found this Userexit and with function module CUDB_SET_VAL it is possible to add new values in the global table cudbd_pr_at_msg of function group CUDB. After calling EXIT_SAPLCUKO_003 SAP calls function module CUDB_PR_GET_AT_MSGS to get changed values.
Is this the only solution to add new values, because exit EXIT_SAPLCUKO_003 has no changing parameters and there is no sample coding in CMOD or other documentations. Please add your sample to show your solution.
Another question : It is possible to change attributes of multilevel instances? For example : Root instance is for material in sales document position, but in sales order BOM there are other configurable materials, which attributes should be maintained by userexit ( external configurator ), too. Normally only root instance is editable, but I want to add new attributes on the lower levels in background.
Best regards,
MarkusHi Markus,
I have the problem that I want to delete some characteristics after configuration befor saving. Therefor I found the same exit and only your question in the web. Did you make further expierence with it? It would be very helpful if you could give me an answer.
Best regards,

Dear All,
Please give me the scenario where we should use an EXIT plug to close an application.
In which hook method should the plug be fired?
What are the possible parameters of the plug?
Thank you.
Regards,
Prosenjit.hi,
Please give me the scenario where we should use an EXIT plug to close an application.
there are two scenarios :
1. When you want to close a Window.
2. When you want to open new window by giving the URL.
What are the possible parameters of the plug?
There are two parameters of this plug:
1. URL of type String.
2. Close Window type boolean.
In which hook method should the plug be fired?
You can call this plug on any ONAction.
Ex :
Do the following steps :
-> Make an Outbound Plug to the Window.
->Make the type of Outbound plug to Exit Type.
->Add URL of type String as a parameter to the outbound plug of Window.
->Do remember to add Component Name in the Properties Tab of View ( othervs Calling Outbound plug of window from view wont b possible ).
To open a new URL with closing the previous one write this Code in OnAction of Button : ( this Code can be get from Code Wizard too ).
DATA lo_zexit TYPE REF TO ig_zexit . <zexit is name of my Component>
lo_zexit = wd_this->get_zexit_ctr( ).
lo_zexit->fire_out_window_plg(
url = 'http://www.google.com' " string
Similarly you can do for Closing a Window using parameter Close Window.
Thanx.

Is it possible to work with Field Exits in R/3 Enterp. Basis 6.20???
How could I work with them?
Yes you can.
SE 38 --> Prog RSMODPRF
http://www.sapdevelopment.co.uk/enhance/fexits.htm
But Have a look at OSS note 29377 as well:
Symptom
Problems and questions concerning field exits
Other terms
FAQ, Q+A, SMOD/CMOD, field exits
Reason and Prerequisites
Note
Field exits are frozen on the 4.6C maintenance level and are not further developed. This means that the existing functionality is kept with all restrictions (see also the last item below). Existing exits can be further used and are called at runtime as usual.
Existing exits can be maintained using program RSMODPRF (run the
program using transaction SE38). Activation of the field exits and
assignment of the dynpros can also be carried out using program
RSMODPRF. For this purpose, the program must be started without
parameters (input fields remain blank).
If required, new field exits can be created using program
RSMODPRF (see the program documentation).
Solution
1. Field exit was created with CMOD, but is not processed when calling the screen.
Since the field exit is not processed until PAI, an action must be triggered on the screen (Return, Save, ...).
Set profile parameter abap/fieldexit to YES and restart the system.
After activating the function module FIELD_EXIT... and the field exit, leave the transaction on whose screen the field exit is to be executed. The screen is not generated until the transaction is started.
Do not work on different application servers since there may be some delay before the field exit is activated.
The profile parameter must be set on all or none of the application servers.
If the field exit is to only be active on specific screens, check whether you chose the correct program and the correct screen number (take care with subscreens).
Generate the screen on which the exit should be active using SE51. It is possible that it was not correctly generated. If you want to be sure that all screens that use the data element are regenerated, you can transfer Report rsmodfdg from the correction instructions and start it with SE38. The Report uses the affected data element as the input parameter and regenerates all screens that use the data element.
Using SE51 -> Field list, check that the screen field does have a reference to a data element. In the name of the field exit, use the name of the data element and not the field name.
After transport, field exits are marked as active but will not be processed. Tip: First try deactivating the field exit once more and then activate it again.
2. How is performance affected by setting abap/fieldexit?
If a screen is generated and the profile parameter is set, a check is run on 2 tables (TDDIR, TDDIRS) to see whether a field exit must be generated for the respective field. In practice, the screen load is not generated until the screen is selected after an update. The user should not notice any difference because screen generation is very fast.
3. Can you read the contents of other screen fields in the field exit?
In principle, every field exit can store its value in the global variables of the function group (TOP) and hence make them available to other field exits. Note here that field exits are always called, not only if an entry is made in the field or if the field is empty. In addition, it is not possible to make any assumptions about the order in which the field exits will be called in the future.
4. How does the field exit behave on step loop fields ?
After the user has entered data, the field exit is called in PAI as often as there are visible fields in the step loop. The system variable SY-STEPL is incremented each time. If a new value is assigned to the field, it is displayed in the module between LOOP and ENDLOOP. This module is also called once for each visible step loop line.
5. Can field exits be debugged ?
No. Field exits must be tested separately in the ABAP/4 Development Workbench. For errors which only occur in the screen environment, it is helpful to write interesting variables to the file system using TRANSFER... . These can then be analysed there.
6. What can you do if the field contents are no longer transported to ABAP/4?
Check whether a value is assigned to the field OUTPUT.
7. When is the field exit called if a conversion exit is attached to the data element?
The field exit is called after the conversion exit. This means that the INPUT field receives the data in the same format as the ABAP/4 program receives it.
8. Although a global field exit is inactive, a function module is called which does not exist (for example FIELD_EXIT_PROGRAMM_@). This can lead to an ABAP dump error when function module FIELD_EXIT_<data element name> is called.
This is an error in the kernel which no longer occurs as of Release 3.0C. As a temporary measure, it is useful to assign a program and a screen which do not exist to the field exit and then activate the field exit.
Due to performance reasons, the active/inactive indicator is stored in the screenload. This can cause inconsistencies between Source and Load. Generate the affected screen with se51. If you want to be sure that all screens that use the data element are regenerated, you can transfer Report rsmodfdg from the correction instructions and start it with se38. The Report uses the affected data element as the input parameter and regenerates all screens that use the data element.
9. Field exit is not visible in CMOD, although created.
If you want to create a field exit for a data element, a function module is proposed with the name FIELD_EXIT_<data_element>. This function module must exist for the field exit to work. If you do not create this function module, but do create one with a suffix, the data element is not displayed in CMOD.
10. Field exit is not executed although it is active.
Fields which do not have the 'Input field' attribute usually do not trigger a field exit. The field exit is designed to allow an extended input check. It is therefore only called for input fields - even if they are not ready for input at runtime of the application by LOOP AT SCREEN.
This rule does not apply, however, if the field is located within a steploop. Here the field will be always activated, even if it is invisible.
Field exits can only be executed for fields that are directly related to the dictionary. If the relation is indirect, i.e. via an ABAP declaration (<fieldname> LIKE <dictionary element>), no field exit can be executed.
11. Field exits do not work on selection screens.
Results from the previous item since ABAP-internal fields and never the original Dictionary fields are used on selection screens.
12. Field exists do not work on check buttons.
Field exits are only intended for input fields. As check buttons count as graphical elements, you cannot install field exits on them.
13. How can all screens that use a data element be generated?
If you want to be sure that all screens that use a specific data element are regenerated, you can transfer Report rsmodfdg from the correction instructions into a customer report (e.g. zsmodfdg). The Report regenerates all screens. In this way, you can ensure that active field exits refer to screens and that inactive exits cannot be called on any screen. The Report uses the affected data element as the input parameter. The affected data element is in the name of the exit: FIELD_EXIT_<data element name>.
14. Restriction of usage
Field exit technology was developed for input fields on dynpros and cannot be used for other/new dynpro elements. This means that this technology does not offer support for the new ScreenPainter elements such as graphical elements (e.g. checkbuttons, radiobuttons, dropdown listboxes), controls (except for table controls which are supported like a step loop), or selection screens.

SYNOPSIS
tv_grab_nl_py is a python script that trawls tvgids.nl for TV
programming information and outputs it in XMLTV-formatted output (see
http://membled.com/work/apps/xmltv). Users of MythTV
(http://www.mythtv.org) will appreciate the output generated by this
grabber, because it fills the category fields, i.e. colors in the EPG,
and has logos for most channels automagically available. Check the
website below for screenshots. The newest version of this script can be
found here:
http://code.google.com/p/tvgrabnlpy/
USAGE
Check the web site above and/or run script with --help and start from there
HISTORY
tv_grab_nl_py used to be called tv_grab_nl_pdb, first released on
2003/07/09. The name change was necessary because more and more people
are actively contributing to this script and I always disliked using my
initials (I was just too lazy to change it). At the same time I switched
from using CVS to SVN and as a result the version numbering scheme has
changed. The lastest official release of tv_grab_nl_pdb is 0.48. The
first official release of tv_grab_nl_py is 6.
QUESTIONS
Questions (and patches) are welcome at: paul at pwdebruin dot net.
IMPORTANT NOTES
If you were using tv_grab_nl from the XMLTV bundle then enable the
compat flag or use the --compat command-line option. Otherwise, the
xmltvid's are wrong and you will not see any new data in MythTV.
CONTRIBUTORS
Main author: Paul de Bruin (paul at pwdebruin dot net)
Michel van der Laan made available his extensive collection of
high-quality logos that is used by this script.
Michael Heus has taken the effort to further enhance this script so that
it now also includes:
- Credit info: directors, actors, presenters and writers
- removal of programs that are actually just groupings/broadcasters
(e.g. "KETNET", "Wild Friday", "Z@pp")
- Star-rating for programs tipped by tvgids.nl
- Black&White, Stereo and URL info
- Better detection of Movies
- and much, much more...

Decrypt the encrypted password
Hi there,
I have been scratching my head for some time to fix one issue. We are planning to change the plateform/technology and we need to bring over existing login to new system. In order to have the same password I need to decrypt the password before I send it to new system. When we stored the password, it encrypts them and stores it in database. I am using following code to decrypt it. it's not worlking . This is error I am getting.
Given final block not properly padded
Here is some more information:
Key is :javax.crypto.spec.SecretKeySpec@18f3a
Format is :RAW
getAlgorithm() is :DES
String encrypted = abcdefgh
Provider is: com.sun.crypto.provider.SunJCE()
This is my code to decrypt which throws error " Given final block not properly padded" :
public String decrypt(String encrypted){
Cipher ci = null;
byte [] result = null;
try {
ci = Cipher.getInstance("DES");
ci.init(Cipher.DECRYPT_MODE, key);
System.out.println("CryptoUtil()" +"before hexToByteArray. Byte Data: "+encrypted);
byte [] encryptedData = hexToByteArray(encrypted, false);
//Log.out("CryptoUtil()" +"after hexToByteArray. lenth: "+ encryptedData.length);
result = ci.doFinal(encryptedData);
catch (Exception e) {
System.out.println("CryptoUtil()" +"ERROR: "+ e.getMessage());
return encrypted;
String strResult = new String(result);
return strResult;
Please help.
Thank you.These are the two values I am getting for encrypted password:
97654de7857cd9aab331995cba044fc6
a125a6b2a71e23adc002ac7fbe1a1042
Is this a hex code?
I think the key is: abcdefgh
This is my code to encrypt and decrypt:

I am displayed a button using web dynpro abap,
if i click the button means a new url page should be
opened in the same window.
I did the application but when i click the button means
a new window is opened.It should not be happened.
Anyone can plz send me the correct coding immediately....>

First of all how is anyone supposed to help you correct your coding when you have posted any. We can't possibly know what is going on inside the event handler for your button. I suggest that post some of your coding here. In general if you want to open another URL in the same page without using the linkToURL UI element, you should consider the usage of Exit Plugs:
[http://help.sap.com/saphelp_nw70/helpdata/EN/45/1bc575ba064574e10000000a114a6b/frameset.htm|http://help.sap.com/saphelp_nw70/helpdata/EN/45/1bc575ba064574e10000000a114a6b/frameset.htm]
Second, please don't ask people to do something "immediately". Everything done in the forum is on a volunteer basis and people help out as fast as possible. Your prompting for immediate action is quite unnecessary and could be considered somewhat rude. -
Getting objects to move between PCs
After CS 150, I find myself back in the world of Java. I recently learned a neat language called Processing (a.k.a. Proce55ing), and I am one of the coders (and am way rusty to be of much use at this point) for a really cool project.
I'm wondering if I can nag you with some questions on java.net.*. I need to get some objects passed around between 3 PCs. I need to know about latency issues. Basically, we've got Java doing OpenGL graphics on 6 projectors powered by 3 computers. Imagine each PC having a really wide screen... when a autonomous creature gets to the edge of one PC, it needs to continue its thang on the next PC... move fluidly.
I've checked out some Java.net.* sample code on sun's site. Specifically their KnockKnock Server. However, its multithread support is for interacting with clients on a one-on-one basis... not like a chat-room style environment. So, I don't even have any sample code for a ultra-basic Java Chat Room.... nor do I know how to pass anything but a string to the server, or to the client.
There are ways to use my limited knowledge to do what I want to do... just pass a string, and have the server store that into a variable which is accessible by every server thread. Then, create a loop in main that keeps searching through that array of strings to pass them off to the PC... the string would have the coordinate information of the autonomous creature, and create a new one of that object with those Vec3f point. However, latency is a key issue, and it would be easiest if I could just pass an object to the server (in this case: a SimpleVehicle) along with an intended target computer, and then that computer would get that vehicle to add to its array of SimpleVehicles. The important thing is speed, so it might be best to have every computer have a client<->server connection with each other... I get utterly baffled reading the Java Docs. But, I seem to understand code when I see it (I can only reverse engineer). I especially understand the KnockKnock Server and MultiClient code on the Sun's Java Networking Tutorial.
Any pointers to which methods I need to learn (I already realize I'm going to need to downcast the SimpleVehicle object back into a SimpleVehicle after it gets sent). Thanks a million.Ok, try this.
The simplistic application sends colored balls between instances of itself which can be on any machine on your network.
As a ball reaches the left side of the window it is in, it gets sent to the machine on it's left (if any), likewise if it reaches the right side of the window it gets sent to the machine on it's right. If there is no machine on the side the ball is trying to go, it rebounds within the window it is in.
So, a simple test is to run three instances on the same machine, one is regarded as one the left on as on the right and one as in the middle
To start the one on the left:
java Ziniman1 8000 -right localhost:8001
To start the one in the middle:
java Ziniman1 8001 -left localhost:8000 -right localhost:8002
To start the one on the right:
java Ziniman1 8002 -left localhost:8001
Note: You need to start these pretty quickly one after the other or the socket creation will time out. I'll leave that to you to fix ;)
Once the apps are running, move them so they are next to each other, left to right (the port numbers used as the server port are in the JFrame title).
To get create a ball, just click on one of the white panels, use the radio buttons at the bottom to change size/color/direction of the new balls.
Once you've got the hang of the thing, try moving some instances to other machnes.
Enjoy!

At the mintue i am using JSP pages to display the result however, i am getting different results on the jsp page from what i am getting on the consle.
This is the result from the jsp page
Value Searched on:myspace
1Title:MySpace
2Title:MySpace
3Title:MySpace
4Title:MySpace
5Title:MySpace
6Title:MySpace
7Title:MySpace
8Title:MySpace
9Title:MySpace
10Title:MySpace
11Title:MySpace
12Title:MySpace
13Title:MySpace
14Title:MySpace
The title MySpace is the title of the html document
and from the console this is what i am getting : -
3 total matching documents
1. H:/Lucenetext/output4.html
2. H:/Lucenetext/output8.html
3. H:/Lucenetext/output1.html
Ive been looking at this for a couple of weeks and was wondering if i could have a fresh pair of eyes to look at it.
Any help would be very grateful
Yours

System.out.println("Enter query: " + searchValue); What's the point of that unless you then read some input from the user?
if (line == null || line.length() == -1) line.length() can never be -1. This is rubbish.
// if (repeat > 0) { // repeat & time as benchmark
// Date start = new Date();
// for (int i = 0; i < repeat; i++) {
// hits = searcher.search(query);
// Date end = new Date();
// System.out.println("Time: "+(end.getTime()-start.getTime())+"ms");
// } Remove this junk.
System.out.println(hits.length() + " total matching documents"); This goes to the console. A JSP doesn't have a console so you will never see it - it might be in a log file somewhere if you're lucky.
//for (int i = start; i < end; i++) Remove all this commented-out junk.
for(int i = 0; i<hits.length(); i++)
ArrayList<String> st = new ArrayList<String>();
st.add(doc.toString());
// System.out.println(st);
} As 'st' now gets thrown away this is all junk. Remove it.
System.out.println((start + 1) + ". " + path); See above remarks about the console.
if (title != null)
ArrayList<String> r = new ArrayList<String>();
r.add(result = "Title:" + doc.get("title"));
//System.out.println(result.length());
//result = " Title: " + doc.get("path");
} See above. 'r' gets thrown away. Remove this junk except for the assignment to 'result'.
System.out.println("more (y/n) ? ");
line = in.readLine(); See above re console. You need to think more clearly about the difference between a console application and a JSP. A JSP writes a page of HTML. -

It sounds like you might have a CLASSPATH error... (a search of the Forums should indicate at least 120000 potential posts involving this issue, since last tuesday ;-))
It does seem strange--that is the code actually posted from the file "ShowMethods.java" that you have keyed into a notepad editor of some sort?
What command are you using to compile? -

The entire line of output up until the actual error means absolutely nothing to me or anyone else except you; it is means anything at all, then you need to get into your debugger and start stepping thorugh your code until you hit the error and see what is actually happening, then if you are stuck, write a question stating what the problem is and where it occurs in your code. You chould give some of the variable states in the same scope during the iteration inwhich the error occures, but unless you are willing to do this, I doubt anyone is going to do your debugging for you--paticulary since this is not even your own code. -

Hi,
I have a Java Frame that i want to run in invisible mode. The problem is that i have to set it to visible first, then invisible otherwise it doesn't seem to execute. Also if i set it to ICONIFIED, the program doesn't run until it is maximized.
How can i make it so i never have to make it visible and have it still run?
Thanks for any help.First explain what you mean by "executing a frame". Hi, this is the first time i have done anything in Java. I am trying to run this java program from a C program, but don't want to see the window pop up at all. But if i don't have the f.setVisible(true) where it is, the viewer modules, which are capturing streaming data and writing to bmp's to not work. The same is true if i set to ICONIFIED.
Thanks, hope this helps...
public static void main(String args[])
ms_standalone = true;
Frame f = new Frame(AppID.getAppID().getAppName());
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we)
System.exit(0);
f.setSize(352, 320);
f.setLayout(new BorderLayout());
int numCams = 0;
StringBuffer concatURL = new StringBuffer();
for (int i=0;i< args.length;i++)
String arg = args;
if (arg.startsWith("-")) {
int eqidx = arg.indexOf("=")+1;
if (arg.startsWith("-num=")) {
numCams = Character.getNumericValue(arg.charAt(eqidx));
} else {
usage();
System.exit(0);
} else {
if (concatURL.length() != 0)
concatURL.append("|");
concatURL.append(arg.trim());
// create multiple viewers
Viewer cv[] = new Viewer[numCams];
for (int i = 0;i < numCams; i++) {
cv[i] = new Viewer();
cv[i].m_parameters.put(PAR_ACCESSORIES, "none");
String tmpStr = concatURL.toString() + i + ".a";
cv[i].m_parameters.put("url", tmpStr);
cv[i].m_camNum = i;
f.add(BorderLayout.CENTER, cv[i]);
