Regarding ALV Using container OO ABAP

HI ALL,
I have created an editable alv report using docking conatainer.
i am facing list of problem while need to maintain these activities.
1. I need to save the changes which are made change in the grid layout.
2. As the alv itself gives a option adding a new row and deleting a new row, while doing that i need to capture the previous record value. And assign these values to the first 2 field in the added row.
In order to do how can we deffer the original functionality.
Can any one give some suggestions in order to work.
Thanks and regards,
Naresh

hi,
First you have to take your data into another internal table and then send data for display of ALV.At the time of save you can compare the old internal table with new edited data and based on which you can save the data for it.
SAP will give provision for triggering of our own subroutine before/after the user command method is called. You can call those subroutines for those adding/deleting lines.

Portal using Webdynpro for ABAP

Hi Gurus!
    I am using one portal using 'Webdynpro For ABAP'. It contains Contextual Panel as well as ViewUIContainer. Contextual Panel contains all the reqd options available for user; while ViewUIContainer contains diff views as requested.
   Now, I'm trying to make a copy of that Webdynpro with some other name. What happens is --
Application is not there and when I try to make one - it says
"Interface View Does Not Exists."
Further, when I try to make an Interface View with the new name - it says
"Interface View Does Not Exists."
   Therefore, what I could conclude about the case is -- may be Interface View is default to certain Webdynpro components/interface. Hence, my question is how can I make use of same webdynpro application with some other name. This requirement arises due to the fact that we have to add some more functionalities to that and I dont want to play with the efforts made so far.

Fuba or Class to access the variants of a test data container in ABAP

Hi there,
I think, that I might remember, that there was once a piece of code (Function call or static class method) that allowed one to access the variants in a testdata container within ABAP.
Anybody ever heard of this before?
Thank you & cheers,
Gregor

You can use class "cl_apl_ecatt_tdc_api" for reading test data.

Using container managed form-based security in JSF

h1. Using container managed, form-based security in a JSF web app.
A Practical Solution
h2. {color:#993300}*But first, some background on the problem*{color}
The Form components available in JSF will not let you specify the target action, everything is a post-back. When using container security, however, you have to specifically submit to the magic action j_security_check to trigger authentication. This means that the only way to do this in a JSF page is to use an HTML form tag enclosed in verbatim tags. This has the side effect that the post is not handled by JSF at all meaning you can't take advantage of normal JSF functionality such as validators, plus you have a horrible chimera of a page containing both markup and components. This screws up things like skinning. ([credit to Duncan Mills in this 2 years old article|http://groundside.com/blog/DuncanMills.php?title=j2ee_security_a_jsf_based_login_form&more=1&c=1&tb=1&pb=1]).
In this solution, I will use a pure JSF page as the login page that the end user interacts with. This page will simply gather the input for the username and password and pass that on to a plain old jsp proxy to do the actual submit. This will avoid the whole problem of having to use verbatim tags or a mixture of JSF and JSP in the user view.
h2. {color:#993300}*Step 1: Configure the Security Realm in the Web App Container*{color}
What is a container? A container is basically a security framework that is implemented directly by whatever app server you are running, in my case Glassfish v2ur2 that comes with Netbeans 6.1. Your container can have multiple security realms. Each realm manages a definition of the security "*principles*" that are defined to interact with your application. A security principle is basically just a user of the system that is defined by three fields:
- Username
- Group
- Password
The security realm can be set up to authenticate using a simple file, or through JDBC, or LDAP, and more. In my case, I am using a "file" based realm. The users are statically defined directly through the app server interface. Here's how to do it (on Glassfish):
1. Start up your app server and log into the admin interface (http://localhost:4848)
2. Drill down into Configuration > Security > Realms.
3. Here you will see the default realms defined on the server. Drill down into the file realm.
4. There is no need to change any of the default settings. Click the Manage Users button.
5. Create a new user by entering username/password.
Note: If you enter a group name then you will be able to define permissions based on group in your app, which is much more usefull in a real app.
I entered a group named "Users" since my app will only have one set of permissions and all users should be authenticated and treated the same.
That way I will be able to set permissions to resources for the "Users" group that will apply to all users that have this group assigned.
TIP: After you get everything working, you can hook it all up to JDBC instead of "file" so that you can manage your users in a database.
h2. {color:#993300}*Step 2: Create the project*{color}
Since I'm a newbie to JSF, I am using Netbeans 6.1 so that I can play around with all of the fancy Visual Web JavaServer Faces components and the visual designer.
1. Start by creating a new Visual Web JSF project.
2. Next, create a new subfolder under your web root called "secure". This is the folder that we will define a Security Constraint for in a later step, so that any user trying to access any page in this folder will be redirected to a login page to sign in, if they haven't already.
h2. {color:#993300}*Step 3: Create the JSF and JSP files*{color}
In my very simple project I have 3 pages set up. Create the following files using the default templates in Netbeans 6.1:
1. login.jsp (A Visual Web JSF file)
2. loginproxy.jspx (A plain JSPX file)
3. secure/securepage.jsp (A Visual Web JSF file... Note that it is in the sub-folder named secure)
Code follows for each of the files:
h3. {color:#ff6600}*First we need to add a navigation rule to faces-config.xml:*{color}
    <navigation-rule>
<from-view-id>/login.jsp</from-view-id>
        <navigation-case>
<from-outcome>loginproxy</from-outcome>
<to-view-id>/loginproxy.jspx</to-view-id>
        </navigation-case>
    </navigation-rule>
NOTE: This navigation rule simply forwards the request to loginproxy.jspx whenever the user clicks the submit button. The button1_action() method below returns the "loginproxy" case to make this happen.

h2. {color:#993300}*_Step 4: Configure Declarative Security_*{color}
This type of security is called +declarative+ because it is not configured programatically. It is configured by declaring all of the relevant parameters in the configuration files: *web.xml* and *sun-web.xml*. Once you have it configured, the container (application server and java framework) already have the implementation to make everything work for you.
*web.xml will be used to define:*
- Type of security - We will be using "form based". The loginpage.jsp we created will be set as both the login and error page.
- Security Roles - The security role defined here will be mapped (in sun-web.xml) to users or groups.
- Security Constraints - A security constraint defines the resource(s) that is being secured, and which Roles are able to authenticate to them.
*sun-web.xml will be used to define:*
- This is where you map a Role to the Users or Groups that are allowed to use it.
+I know this is confusing the first time, but basically it works like this:+
*Security Constraint for a URL* -> mapped to -> *Role* -> mapped to -> *Users & Groups*
h3. {color:#ff6600}*web.xml -- here's the relevant section:*{color}
{code}
<security-constraint>

h2. {color:#993300}*_Step 5: A couple of minor "Gotcha's"_ *{color}
h3. {color:#ff6600}*_Gotcha #1_*{color}
You need to configure the "welcome page" in web.xml to point to faces/secure/securepage.jsp ... Note that there is *_no_* leading / ... If you put a / in there it will barf all over itself .
h3. {color:#ff6600}*_Gotcha #2_*{color}
Note that we set the <form-login-page> in web.xml to /faces/login.jsp ... Note the leading / ... This time, you NEED the leading slash, or the server will gag.
*DONE!!!*
h2. {color:#993300}*_Here's how it works:_*{color}
1. The user requests the a page from your context (http://localhost/MyLogin/)
2. The servlet forwards the request to the welcome page: faces/secure/securepage.jsp
3. faces/secure/securepage.jsp has a security constraint defined, so the servlet checks to see if the user is authenticated for the session.
4. Of course the user is not authenticated since this is the first request, so the servlet forwards the request to the login page we configured in web.xml (/faces/login.jsp).
5. The user enters username and password and clicks a button to submit.
6. The button's action method stores away the username and password in the request scope.
7. The button returns "loginproxy" navigation case which tells the navigation handler to forward the request to loginproxy.jspx
8. loginproxy.jspx renders a blank page to the user which has hidden username and password fields.
9. The hidden username and password fields grab the username and password variables from the request scope.
10. The loginproxy page is automatically submitted with the magic action "j_security_check"
11. j_security_check notifies the container that authentication needs to be intercepted and handled.
12. The container authenticates the user credentials.
13. If the credentials fail, the container forwards the request to the login.jsp page.
14. If the credentials pass, the container forwards the request to *+the last protected resource that was attempted.+*
+Note the last point! I don't know how, but no matter how many times you fail authentication, the container remembers the last page that triggered authentication and once you finally succeed the container forwards your request there!!!!+
+The user is now at the secure welcome page.+
If you have read this far, I thank you for your time, and I seriously question your ability to ration your time pragmatically.

If you want login security on your web app, this is one way to do it. (the easiest way i have seen).
This method allows you to create a custom login form and error page using JSF.
The container handles the actual authentication and protection of the resources based on what you declare in web.xml and sun-web.xml.
This example uses a statically defined user/password, stored in a file, but you can also configure JDBC realm in Glassfish, so that that users can register for access and your program can store the username/passwrod in a database.
I'm new to programming, so none of this may be a good practice, or may not be secure at all.
I really don't know what I'm doing, but I'm learning, and this has been the easiest way that I have found to add authentication to a web app, without having to write the login modules yourself.
Another benefit, and I think this is key ***You don't have to include any extra code in the pages that you want to protect*** The container manages this for you, based on the constraints you declare in web.xml.
So basically you set it up to protect certain folders, then when any user tries to access pages in that folder, they are required to authenticate.

Why and how to use events in abap objects

Dear all,
Please explain me why and how to use events in abap objects with real time example
regards
pankaj giri

Hi Pankaj,
I will try to explain why to use events... How to use is a different topic.. which others have already answered...
This is same from your prev. post...
Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.
Cheers.
Varun.

Error (Error when starting a SWITCH branch) while using container operation

HI Experts,
I am using container operation step for moving internal table (ref to sflight) to workarea.The error I found in the log is ' Error when starting a SWITCH branch'.Kindly help me in finding the solution.Below are the steps and code.
Result Element = lw_sflight             (Element ref to sflight with export and Import)
Assignment     =    =                     (Assign (contents of table are deleted first)
Expression      = &FLIGHT&             (Multi line container ref to sflight)
Operator          = Assignment
Expression      =                                 (Blank)
Thanks and Regards,
Srini

Hello,
Maybe you should show more information about the condition step instead of the container operation step.
A previous poster in SDN said they solved their problem by changing the order of the conditions.

Adobe form to save data using Web Dynpro ABAP

Hi. I am pretty new to SAP world and trying to learn and work on a task given to me relate to
creating Adobe offline form using Web Dynpro ABAP same time.
I have several questions and hopefully, many gurus like you will provide answers.
I noticed there are many examples creating and using Adobe interactive forms (though not many newer version),
but I didn't see (at least I didn't find any) any detail example on saving data to an internal table (such as fixed assets, vendor master, etc)
using interactive form. Is there any detail explanation/example on this?
I have ask this question in another forum (before I found this forum) but didnu2019t get the answer yet.
2. When I tried to see graphic layout and modify the layout from Web Dynpro, I can't see the graphic layout.
All I see is text list of fields/buttons that I created, but can't see section for graphic layout where I can modify layout.
I am sure I didn't install/configure something correctly.
Anyone has any idea what I didn't do?
I have another question, but I will wait till later after I figure out above ones first.
Thanks for all your help in advance.
John

Hi John,
In the WD4A view, there is a button "Show/Hide Layout Preview".
Click on that button to be able to see the Layout.
Note that this button is next to the Pretty Print button.

Using Container Object in Java Mapping

Hi All,
I need to use a Container object inside a Java Mapping, just like the one wich is used in the Graphical Mapping.
Here is the scenario:
I have an Interface Mapping with three steps on it.
The first step is a Java Mapping just to put some info in the Container. The second step is a XSLT transformation that uses an XSLT file to transforms from IDOC to xCBL. The third step is another Java Mapping that get the info from the Container and insert in the xCBL.
Does any one knows how to do it inside the Java Mapping Code? We cannot make modifications in the XSLT file because of some internal restrictions.
Thanks,

Hi,
If you make the container variable is a part of your message (input of Java Mapping) then you can access as normal fields.
Just have a look at these discussions-

How to use wildcards in ABAP query where condition?

Hi,
Please tell me how to use wildcards in ABAP qurey where condition.
e.g. select * from mara where matnr = * (wildcard we need to use.
Thanks & Regards,
Gaurav T

Do you want to query asterix * ?
select * from mara where matnr = '*'. "then just put it in apstrophes
or you want certain part of string be used as * ?
select * from mara where matnr like '%*' "then use % sign before it
or maybe you want something like this
select * from mara where matnr like '%1' . "then it will look for all materials having '1' inside it

Sales order creation using webdynpro in ABAP

Plz give the process how to create sales order creation using webdynpro in ABAP. if not possible plz let me know how to create in JAVA.
It is very urgent. I hope i will get it very soon.
Thanks all

In your WDA application, all you need to do is call the BAPI BAPI_SALESORDER_CREATEFROMDAT2 when the user clicks some button. Most likely, you can put the code for this BAPI call in the onAction method for your button.
