How to add UI Commands to MenuActionItems in web dynpro

Hi all,
is it possible to use UI Command Groups or UI Commands in web dynpro menu?
I have a Menu with MenuActionItems in my web dynpro app. I'd like to use finished configured UI Commands from the portal like new -> new folder...
I don't know how to bind the UINewFolderCommand to my MenuActionItem, and I don't want to reinvent the wheel.
Thanks a lot for your help!
Steffi

Nobody?
Maybe somebody knows which URL I have to call to use the given upload iview?
I want to create a menu in my web dynpro which calls this upload iview. I want to use the available iview and don't know how to call it...
Thanks a lot
Steffi
P.S: it's understood that points will be awarded!

How to add new class to existing DC (Web Dynpro project)

Hi,
How can I add new class to an existing DC (Web Dynpro project)?
I tried adding it using File - New - Other - Java - Class, but after a build of the DC the new class (and its contents ) was completely removed.
Then I created a new DC (java project) and created a new class in that DC. This went fine, but I got into problems because of circular referencing between the new & the old DC, so no build was possible.
This can't be difficult, does somebody knows how to do it?
My temporary solution is to add the classdefinition to an exisiting .java file. Very ugly.
Thanks,
Jeroen

Hi Jeroen,
where did you create the class? If the *.java file is placed in the src/packages folder it should not be deleted by a build. (I suspect you created it in the gen_wdp folder?)

How to add a javabean Model to a web dynpro Project

Hi all,
I have been following the tutorial "Using EJBs in Web Dynpro Applications" for creating a customized LOCAL webdynpro application, based in javabean Model. It was made by just exporting the JAR file from a java project, as it is explained in the tutorial. OK.
The problem comes when I want to duplicate the development but using a DC Web Dynpro Project. I have re-develop every step of the tutorial but using DC projects:
DC diccionary project, DC ejb project, DC enterprise application project & DC java project.
But now I DO NOT KNOW the steps for importing the development into a model for DC Web Dynpro.
Anyhelp will be very appreciated, thanks in advance-

Thanks Jhansi,
Yes, you are right. I had already followed those steps. The error comes when I have to select between the JavaBean Source:
1. project (source folder) (checkbox)
2. public parts of used DC's (combobox)
I have been trying both, the second one by copying first the JAR called CommandBean.jar of my DC Java Project with dependencies to EJB project into the web dynpro "lib" folder, and then selecting the new entry CommandBean.jar from that combobox.
then i get de following error: "Invalid JAR - No JavaBeans available for import"
So I do not know how to use any of these two options for java source.
Thanks.

Have you saved that VC element as template and using that template in another component?.If so,on resuing that VC element template it populates all the screen elements which you've save as template.
Now, select that VC element which you've re-used,based on you're requirement add/remove UI elements as Kiran suggested.
Hope it will resolve your issue.

How can I set the data binding between Web Dynpro & Database table

Dear friend,
I am a beginner of Web Dynpro. I want to develop my simple project like these:
1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
1. How can I set the data binding between Web Dynpro and Database table ?
2. Are there any nescessary steps that I will concern for this case?
Sorry if my question is simple, I had try to find solution myself, but it not found
Thanks in advances,
SeMs

Hi,
You can write your own connection class for establishing the connection with DB.
Ex:
public class ConnectionClass {
static Connection con = null;
public static Connection getConnection() {
try{
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
con = ds.getConnection();
return con;
}catch(Exception e){
return null;
You can place the above class file in src folder and you can use this class in webdynpro.
You can have another UserInfo class for reading and writing the data into the DB .

Hi Gurprit,
A null value is being passed at runtime. Make sure that you enter values when filling in the form.
Also check for the cardinality of the nodes being used. You can also initiliaze your value attributes as follows:
In wdDoInit() method:
wdContext.currentNodeAElement.setValueA("");
Context is as follows:
RootNode
|____NodeA
        |_____ValueA
Hope it helps.

How to add new validation for the iProcurement web page?

Hi,
I am very new to OA Framework. Can you experts give me some guidance on how to proceed with the following customization?
My requirement is in iprocurement when you open a new cart and check out on "ICX_POR_SHOPPING_CART" there is a Project Field and reference to Charge account. If the users go to charge account (ICX_POR_CHECKOUT_SUMMARY) and enter the segment values ( which includes project segment) and enters a value in project segment other than '000000' with out entering the Project Field on "ICX_POR_SHOPPING_CART" the page should give error.
Please give me some suggestions on how to proceed.
Thanks
Vish

I need the client side validation. By saying server side validation if you mean writing a triger on tables to validate then I am thinking to take that option as last resort.
Can you please tell me what is PPR ( Is it personalization?) stands for.? In my case the Charge Account is DFF.
Can you direct me to any documentation on how to add custom javascript to achieve my objective?.
Thanks for your Help.

How to add an input field in the web UI of CRM 2007

Hi everybody.
I want add an Input field in the Web UI Screen. How it is possible.
I want get the information with detailed descriptions if possible with screen shorts.
What type of methods it will be generated and what are the code we entered in those methods.
Take according to any example. But with detailed description.
I am new for the CRM 2007. So, please give the screen shorts with proper data.
Not only adding the field. If any data i entered in the adding field then that will be stored in the tables otherwise no use by adding the field.
So, Can anybody please send a proper information according to this.
Here another one How to Add our own table (Ztable) field in the Web UI Screen.
How to add the same field in the BOL.
Please expalin about those concepts with full of screen shorts messages.
Thank You.
Regards,
Krishna.

If you want to add extra standard fields (like one you mentioned), you can use Component Workbench and Copy the configuration and create your own configuration and make the "Available Fields" appear there.
If the standrd field is not available, you can Add Context Node using wizard and make it visible.
If its a custom field (a new one); you will have to use EEWB and add the fields and then make it visible in the UI using Component Workbench.

Alin

How to input multiple records in tables in web dynpro

Hi
In web dynpro table I am able to input data in first row only. How to input data in other rows.
Thanks,
Saurabh

hi, okay..
I summarize in 3 aspects:
1.You want make the Table row play like "Input field"
The solution is :
In the table column, you set the cell editor as "Input field"
2.You want to use the FILTER function
The solution is :
set Filter Value property and realize "OnFilter" event...
3.You want to add Ready for Input rows to your table
The solution is :
You should make use of the Context Node bound to the table. The EXAMPLE coding:
DATA lo_nd_flights TYPE REF TO if_wd_context_node.
DATA lo_el_flights TYPE REF TO if_wd_context_element.
* append the element with initial attribute value
lo_nd_flights = wd_context->get_child_node( name = wd_this->wdctx_flights ).
lo_el_flights = lo_nd_flights->CREATE_ELEMENT( ).
* bind the newly created element
lo_nd_flights->BIND_ELEMENT( new_item = lo_el_flights
set_initial_elements = abap_false ).
4.You want to set N rows ready for input initially
The solution is :
Set the Row visible property..
Best wishes.

How to use data from standard view in Web dynpro for ABAP

Hello:
I have to create an Abap Web Dynpro, and I must use data from a standard view in the new one. Does anybody know what do I have to do?
Thank you and have a happy new year.

Hi Rodrigo,
Firstly, list the Standard component under Component Usage of the Component which you are creating in your View.
Second, In the Custom Component, view, goto context, and try to add the node from the Standard component in to your view.
NOTE: The second step requires a Node in component controller of the Standard Component.
Finally, Now in your view, get the data from that and map the data.
NOTE: To do this, I think you need to call your Standard WDA first and then only your node contains data and it will be passed.
I hope it is helpful.

Shashikanth. D

How to get a r/3 file using web dynpro

Hello Experts.
Actually I have a new request, I hope you can help me please.
I'm a web dynpro programmer (java), so my company need to take a r/3 file to download at the local pc. In fact, the file is en r/3 already.
The matter is, i have no idea how to get that file since my web dynpro app. to download it. the file is a compressed file may be a .ZIP file... so any of you can let me see the light in this??
thak you all.
walex

Hi Walex,
You will first need a RFM that returns the file that you need.
Then you can create a Adaptive RFC model in Web Dynpro to access this RFM and store the file in the Web Dynpro context. Web Dynpro provides APIs to save files to the local system
You can check this article for downloading the file.

The Sap-Notes 962319:
1. Check in the Visual Administrator, "Licensing Adapter" -> "General" -> "SystemType" !
If it is set to "DEVELOPMENT_MODE", verbose error messages are shown.
If it is undefined, proceed with the next step.
If it is set to something else, only exception IDs are shown. In this case the only chance is to search for this exception ID in the default traces.
2. If the system type is undefined, then in the Config Tool "Configurations" -> "webdynpro" -> "sap.com" -> "tcwddispwda" -> "Propertysheet default" -> "DevelopmentMode" is evaluated. If it is "true", verbose error messages are shown.
3. If verbose error messages are required but still the short version is shown, you probably face an error message that is not raised by Web Dynpro but by other components of the NetWeaver. In the Visual Administrator set "Properties" -> "HTTP Provider" -> "DetailedErrorResponse" to "true".
4. In addition to the error page shown in the browser or client, important messages - including error messages and stack traces - are written to the log and trace files, e.g. to the default traces usr\sap\<SID>\<instance>\j2ee\cluster\server<number>\log\defaulttrace.trc.<number>.
a) In some cases, when an exception ID is included in the error message, the detailed error message can easily be retrieved in the log file.
b) When no exception ID is given, you have to search for the detailed error message in the log specifying time stamp and/or user ID.
Always consider restarting the system after making changes on the settings.
It is not recommended to switch the "SystemType" to an inappropriate value just for viewing verbose error messages. The system type potentially affects framework, applications and licensing in an perhaps unintended way.
In the past there was no distinction between different system types regarding error messages. For security reasons this distiction has been introduced. It is not intended to show stack traces in non-development systems in the future. SAP does not provide workarounds or patches to enable such a behaviour again.

How to link the ALRTINBOX in a ABAP Web Dynpro application?

How can I link the ALRTINBOX window in a web dynpro application view?

Hi Rahki,
The status of what?
There are traffic light icons that you can use, or you can set the cell design (which changes the background colour of a cell (if you are in a table).
I often use this to indicate on a review step whether a cell/row has been inserted, modified or deleted from a table.

How to use the catalog in our own Web Dynpro program?

Hi Expert,
How to access MDM catalog and bring the product data back to a our own Web Dynpro program?

Hi Masa,
The Catalog Search UI of SRM that is referred to as UI as aforementioned is a page which is capable of the selection of catalog items is linked from the shopping cart creation.
Our biz requirement content two scenarioes to processing the purchase requirement.
A. Create shopping cart via the catalog (PR) --> SRM PO Process --> SUS(PO and Invoice)
This is the standard SRM purchase scenario and we have already implemented that.
B. Create a requirement document via the catalog (This document is same with the SC but very simple, and we create this function by the own web dynpro program) --> transfer the requirement document to other purchasing system(none SAP) in our intranet.
So the key problems we faced are below:
1. How to connect to the catalog search UI from our own web dynpro program.
( If we connect the catalog via the MDM ABAP API, that will make the catalog serach UI could not be used;
Also it has been failed to simulate the function of SC's connection to the catalog;
So we decide to link the catalog serach UI via the URL, the linkage is "http://<J2EEserver:J2EEport>/SRM-MDM/SRM_MDM?sap-locale=EN&HOOK_URL=&mask=&namedSearch=General&username=&password=&catalog=<Repository Name>&server=&datalanguage=EN". )
2. How to transfer the catalog item data to our own web dynpro program.
If we link the catalog search UI by URL, we can not find any good method to transfer the catalog item data to our own program.
