Naming Conventions of Web Dynpro Wizard

Hello everyone,
is it possible to change the naming conventions of the coding generated by the web dynpro wizard?
According to our internal naming conventions object references (type ref to) are to be named LR_name, but the wizard is calling them LO_name.
Thanks in advance and best regards,
Alej

The templates/code fragments used by the wizard for generation are in the class CL_WDY_RG_FRAGMENT_TOOL, which in turn navigates down to local classes in the WDY_RG_CODE_TEMPALTES Function Group. For instanace the Context code fragements are in the local class LCL_COMPLEX_FRAGMENTS of this function group.
The fragements aren't in reusabe or customer maintable templates unfortuetely. They are built with CONCATENATE statements in these local classes. Newer developments (like the ABAP Code Completion in 7.02) use the ABAP Template Language (ATL) and have a tool to maintain these templates directly. However for the WD Code Wizard, you would have to use the Enhancement Framework or Modification Assistant to adjust the concatenate statements in the local classes.

NAMING STANDARDS FOR WEB DYNPRO ABAP

Hi All,
Do we need to follow any naming standards in WebDynpro ABAP, could you please send some documents or any links for Naming Standards .
Thanks,
Raju.

Hi Raju,
This is a very good question which we cant answer as we are not working in your company.
Well, the naming conventions standards vary based on different company Standards. So the best I could say is, check out your company Standards documents to get to understand the Naming Convention standards.

Web Dynpro for ABAP Naming Convension & Guide line

Hi, everyone.
I have a plan to implement Web Application as WDA(Web Dynpro for ABAP). but I don't know how can I give a name to Windows or Views or Custom controllers.
If you have a naming convension or guid line document,
Could you share the document with me? ^^

As Rich said, there are no official naming conventions. Nonetheless, a few things have become quite popular, such as:
- adding wnd_ in front of window names as they share the same namespace with views
- adding m_ in front of member variables of controllers
- adding s_ in front of supply methods and using the name of the node afterwards
- adding lbl_ in front of labels and using the name of the labelled ui element afterwards like "lbl_customer" and "customer"
Some developers also add certain prefixes to view elements to distinguish between them.
Regarding the names of components, there is one thing that you should not do: Start them with WD_ or WDR_ as both are somehow preserved. The same is true for entities within a component, although there checks in place that prevent you from doing that.
Best regards,
Thomas

Web Dynpro ABAP Naming Guideline

In Web Dynpro Java SAP has published a guideline for Web Dynpro Naming Conventions. Is there such a document for Web Dynpro ABAP?

Web dynpro application not available when running iview wizard

When I run the iview wizard to create a web dynpro iview I find the folder local/<MyProjectName.
But when opening myProjectName folder the Application is missing, so I cannot create the iview.
When running the web dynpro Content Administrator I find the application in the ProjectName folder, but when I try to run it I get the exception:
com.sap.tc.webdynpro.repository.utils.RepositoryException: Did not find application 'MyTestApplication' in repository.
What could be the issue?

NW 7.3 + iView from remote source wizard + R3 Web Dynpro ABAP, not working

Hi,
I think this forum is my last resort.
I'm running NetWeaver 7.3 Enterprise Portal and also have an existing ECC6 on backend.
Our ABAP Programmer has built some WD4A application on ECC, I'd like to made them available
on EP as ABAP WebDynpro iView.
From the document, I know the way to create ABAP WD iView is different since 7.3. I have to use "iView from remote source" to do it.
On EP side, I have made an system alias (test ok) for ECC, assigned permission, provide mapping id/pwd, and test.
On ABAP side, all webdynpro app are activated (T-code sicf, /sap/bc/webdynpro, /sap/public/bc/webdynpro...). I can even test WAS by bringing up browser and access some sample ABAP webdynpro .
However, I cannot success on "iView from remote source" wizard and it always show me "Nothing found. Check your search Criteria.".   Eventhough I use "*" as search criteria.
Anyone has the similar situation ? I even doubt that it is a placeholder of a feature , not working for now. Anyone made it work on NW 7.3 ?
More detail:
My System Alias for ECC:
      Application Host: myr3.mydomain.com
      SAP Client: 600
      SAP System ID:   DEV
      SAP System Number: 00
      Server Port: <leave it blank>
      System Type: SAP_R3
      Logon Method: UIDPW
      User Mapping Type: admin,user
      ICM Host: myr3.mydomain.com:8000
      ICM Protocol: http
      ICM URL prefix: <leave it blank>
      SAP Netweaver AS Description: <leave it blank>
All other fileds are leave it as default value
I also assign a group to have "read" and "user" permission to this system
Also assign Alias to the system.
I also create a user belong to the group, assign his system mapping an ECC user ID & PWD to it.
I tested the System alias, it is working (both WEB AS test, and R3 test)
Then I try to create an iView on EP, under a PCD folder , new->iview->iview from remote source. A wizard show up. Then I can select the ECC alias just created, and provide * as application search criteria, and then select "WEB DYNPRO ABAP" as the application type. Then "GO"
as I mentioned, it always show "Nothing Found. Check your search crieteria"
But I'm sure the web dynpro applications are activated on R3.
OK, that's it, please help this one. Thanks
IF YOU DID MAKE IT WORK ON YOUR NW 7.3, PLEASE DROP A LINE HERE SO I KNOW IT IS MY OWN PROBLEM !!!

Thanks for the reply,
[About Backend]
I feel confident about the backend R3 system because I can use the WAS URL to access the sample WD4A application, for example, I can bring up the wd4a application ui in my browser. It is purely browser and R3 stuff, no EP involved.
http://soeprdev.mydomain.com:8000/sap/bc/webdynpro/bobf/demo_sales_order?sap-client=600&sap-language=ZF
I also already activate all nodes and sub-nodes (in SICF Services) under /sap/bc/webdynpro as well as /sap/public/bc/webdynpro. (and some other nodes to make icon and include work)
[About the system object in EP]
I have done all kind of test on the system object (alias):
1. In EP System Administration -> Landscape Configuration, I select the system object, click "Test Connection", It shows me a Check mark, and the detail message is SOE_DEV_600 connection
2. Edit the System object, then click on "Connection Tests" page, I see two lines there, check both and click test, here is the result:
SAP Web AS Connection:
: Test Details:
The test consists of the following steps:
1. Check the validity of the system ID in the system object
2. Check if the system can be retrieved
3. Check if the system object has a valid system alias
4. Check if an SAP system is defined in the system object
5. Validate the following parameters: Web AS protocol; Web AS hostname
6. Checks if the host name of the server can be resolved.
7. Pings the Web AS Ping service (works only if the service is activated on the Web AS, and only on ABAP Web AS)
8. Check HTTP/S connectivity to the defined back-end application
Results
1. The system ID is valid
2. System retrieved successfully
3. Retrieval of the default alias was successful
4. The system object represents an SAP system
5. The following parameters are valid: ICM Protocol (http) ICM Host Name (soeprdev.mydomain.com:8000)
6. The host name (soeprdev.mydomain.com) was resolved successfully
7. The Web AS ping service http://soeprdev.mydomain.com:8000/sap/bc/ping was pinged successfully
8. An HTTP/S connection to http://soeprdev.mydomain.com:8000 was obtained successfully.
Connection Test for Connectors:
: Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the back-end application using the connector defined in this system object
Results
Default alias retrieved successfully
Connection successful

Web Dynpro Code Wizard doesn't have context tab

When doing web dynpro development and when clicking the Web Dynpro Code Wizard, I can't see the context tab. It looks like this: [http://twitpic.com/z2q92]. In other SAP systems I have seen the wizard look like this, where it has two tabs one of which is the context tab: [http://twitpic.com/z2qgh]. As the context tab is very useful, I would like to know how to get it to display.
I have searched in the SE80 settings and can't find any option related to this. I also searched the forums here and could not find any related posts. We're using the 700 release level 13 (as seen in this screenshot: [http://twitpic.com/z2qkf]). Is there something I can do to make this tab appear? If we need to implement a note or a newer support pack, which one would it be?

As you stated the system without the context tab is NetWeaver 7.0. The context tab and the extra wizards were new features in NetWeaver 7.0 Enhancement Package 1. Your system would have to be updated to this NetWeaver Enhancement Package level in order to have this functionality.

Web Dynpro Model Wizard Exception

Hi there,
I've recently installed the latest Netweaver'04 Sneak Preview and I get the following exception when generating an R3 Adaptive RFC model (using the "create model" Wizard):

Web Dynpro Code Wizard - code patterns

Hello,
the code patterns that are generated by the very helpful Web Dynpro Code wizard seem to be a little inconsistent in their syntax structuring.
If I were to ask the wizard to read me a context node - I would get something like (some bits removed for brevity):
data lo_nd_result type ref to if_wd_context_node.
data lo_el_result type ref to if_wd_context_element.
data ls_result type wd_this->element_result.
* navigate from <CONTEXT> to <RESULT> via lead selection
lo_nd_result = wd_context->get_child_node( name = wd_this->wdctx_result ).
* get element via lead selection
lo_el_emp_search_result = lo_nd_emp_search_result->get_element( ).
* get all declared attributes
lo_el_emp_search_result->get_static_attributes(
    importing
      static_attributes = ls_emp_search_result ).
Yet if I were to ask the wizard to generate a message I would get:
* get message manager
data lo_api_controller     type ref to if_wd_controller.
data lo_message_manager    type ref to if_wd_message_manager.
lo_api_controller ?= wd_this->wd_get_api( ).
call method lo_api_controller->get_message_manager
   receiving
     message_manager = lo_message_manager
* report message
call method lo_message_manager->report_t100_message
   exporting
     msgid                     =
     msgno                     =
     msgty                     =
*     p1                        =

post split to avoid silly size/formatting limits
Ok - both work - but one is using the:
result = class_ref->methodname( parameters = paramvalue )
and one is using
call method class_ref->methodname
                                  exporting parameters = paramvalue
                                receiving result = result.
As I often have to review code written by others, I encourage them to use these wizards - it helps speed code and prevents simple mistakes. But code that contains multiple different syntax structure approaches is harder to read (albeit only slightly), moreover - it looks sloppy.
But why are they not consistent in their syntax structure? (one could also argue why do we have multiple syntax structures for the same operation - but that's a different discussion).
Is there some way customers can update these structures to match with their own internal coding standards - or something we can change so that they go one way or another?
I look forward to other's thoughts on the same topic.
Cheers,
Chris

Web Dynpro Code Wizard in WDJ??

Hi Guys,
in Web Dnypro ABAP I frequently use the Code Wizard Tool to generate source code, call methods in controllers etc.. I guess you know what tool I mean..
Is there such a thing for Web Dynpro Java as well?? Let me know!!
Later, Johannes

Hi,
there is no code wizard in webdynpro Java. But You can use cntrl+space to see methods.
Example you just type wd then press cntrl+space then you can see all the interfaces and classes starting from wd like wdcontext,wdcomponentAPI etc. After that press dot(.) and see the methods under it.
I hope it helps.

Rohit

UI-Type using the Web Dynpro Dode Wizard

Hi,
every time i use the Web Dynpro Code Wizard and choose the Form i still get the UI-Element-Type "InputField". Is it possible to select ohter Element-Types for example DropDownByIndex or Text_Edit?
i hope we can fix this.
best regards,
Michael

Ofcourse you ca change it to UI-type that you want.
change the Standard Cell Editor to DropDownbyKey all the UI elements will change(Default it will be InputField because most of the forms contains more number of InputFields ), also you can change the individual context attribute UI type also by changing the CellEditor of a table Column.

Hi Peter,
We have already faced this problem in our company with Windows Vista machines. So, if you have Windows Vista, try to run NWDS under Administrator account and in Windows XP compatibility mode...
If not, probably you should re-install your NWDS.

Problems creating new Web Dynpro ABAP application

All,
I am following this tutorial to create my first Web Dynpro ABAP application
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/fc/501b42b5815133e10000000a155106/frameset.htm
In this tutorial I was asked to create a component as Local object.
But after giving the name of the component, I get an alert saying
"Object can only be created in SAP Package"
When I confirm this, I was shown a "Create Object Directory entry" dialog box which asks for attributes like Package.
And this box has Local Object button, when clicked I get the message "Test Objects cannot be created in foreign namespaces".
I found some other article through Google
http://www.octavia.de/fileadmin/octavia_files/content_bilder/Hauptnavigation/SAP_NetWeaver/WebDynpro/Web_Dynpro_Part_I.pdf
According to this, I tried to give $TMP as Package. But still have the same error
"Test Objects cannot be created in foreign namespaces"
Where am I and what should I do to create a new project?
Thanks.

Thanks Abinav.
My problem is with naming convention only. Component name starting with Z solved my problem.

Incorporating web service in an ABAP web dynpro view

Hi,
I am trying to call an external web service to have its results displayed in an ABAP web dynpro view. I've seen various threads that are dealing with the same issue, but none of them seemed to have helped me (I am quite new at this so maybe I'm just having a slow beginning, please bear with me)
I'm interested in extracting information from a simple web service online. To this end, I went on www.xmethods.net and found a "quote of the day" service, which is practical because it doesn't even need input.
I am writing down all the steps I've taken, even if they seem trivial, because maybe my problem is the result of a silly mistake I'm not yet capable of noticing...
I am mostly following the instruction from here:
<a href="/people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap:///people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap
The SAP I use is the one on the SC7 system, seems to be ECC 6.0
After I created my package, I go on to create a Proxy Object, and when prompted for a WSDL source, I give the URL destination I got from xmethods.net: <a href="http://www.swanandmokashi.com/HomePage/WebServices/QuoteOfTheDay.asmx?WSDL">http://www.swanandmokashi.com/HomePage/WebServices/QuoteOfTheDay.asmx?WSDL</a>
Doing this I get an HTTP error (return code 400, message "ICM_HTTP_CONNECTION_FAILED") (others have had this problem, e.g. Calling Web Services from ABAP, but the answers offered haven't been much help to me)
and having no idea what to change or not change in SICF and other settings, I decided to save the file locally, and so I then created a Proxy Object by choosing the WSDL source as the local file I saved.
Telling me that multiple port types exist (SOAP, httpGet and httpPost) I picked SOAP. I can then see the properties of my Client Proxy Object, its structure with the classes and methods etc.
Then, following Thomas Jung's procedure, I went to create a logial port which I named QUOTE_PORT. When I do the F8 test he suggests to do, I get an error: SRT: Processing error in Internet Communication Framework: ("ICF Error when receiving the response: ICM_HTTP_CONNECTION_FAILED") which was predictable since I still haven't resolved that same problem above.
I then proceed to create a Web Dynpro Component. In that component, in the component controller's context, I created a simple node into which I added attributes which I created using the wizard -> Attributes from components of structure, and there I picked the structures that had just been created in my proxy object, each in its own node
I have three proxy structures generated: GET_QUOTE_SOAP_IN, GET_QUOTE_SOAP_OUT and QUOTES. This last one has two attributes which are STRINGs, the quote of the day and its author.
I then create a rather trivial view, whose context I have mapped to the component controller's context so as to have access to those "quote" and "author" attributes I just mentioned. The layout is simplistic at best, containing only two textviews, each one bound to its respective attribute.
Once the application has been done and tested, the output is a blank page. I'm hoping that this is only because of that ICM_HTTP_CONNECTION_FAILED error. Has anyone else had these problems when calling external web services? Is this the right procedure for displaying output?
Thanks and Regards,
Micol

Hi, sorry for the long reply time.
from work I do have proxy settings:
automatic configuration script: http://proxy:8083
proxy server for LAN: proxy / 8080
from home it's a proxy free connection.
In both cases I tried changing the settings in the SICF transaction, but it hasn't changed much.
With the HTTP error that I get, I get a long text on how to maybe solve it,
<b>No connection to Integration Builder (only generic data visible)
Message no. SPRX081</b>
In this long text, I have four tests to do in order to check the connection (as far as I can understand)
1. The address of the Integration Builder must be stored in the SAP system
=>Check/maintain with report SPROX_CHECK_IFR_ADDRESS
2. The HTTP connection of the ERP application server must function correctly
=>Check with report SPROX_CHECK_HTTP_COMMUNICATION
3. The Integration Builder server must be running correctly
=>Check with report SPROX_CHECK_IFR_RESPONSE
4. Proxy generation must interpret the data of the Integration Builder correctly
==>Check with report SPROX_CHECK_IFR_CONNECTION
The checks for 1&2 work okay, but I get errors for checks 3&4
"Integration Builder data not understood"
How can I go on from here?
Thx

Is abap web dynpro is a netweaver product?

Dear experts,
is abap web dynro is a netweaver product? ..i wonder why is it categorized under application server in sdn forums can anyone explian..
in addition to abap i am willing to learn abap web dynpro.how would be the prospectes of abap web dynpro in the us market ...or do u suggest any other hot topic to learn?..please feel free to comment on my idea and kindly suggest me a better option if my idea is not ideal....
i am not into java till now so i am not willing to learn java web dynpro..
please suggest a better option so that i can use my abap skills to the fullest..
thanks in advance.

Hi Ramu,
Yes, ABAP Web dynpro is a Netweaver product. It cums with mySAP suite.
This is the hot technology in the market and if you are not a JAVA guy then you must go with ABAP Web dynpro.
Basically with the help of ABAP Web dynpro we develope custom products for the client. this is UI based technology and one of best option for "ABAPers" .
For Web dynpro ABAP you will require SAP ECC 6.0 onwards and WAS 7.0
is a must. It has very good future propspects as this is best UI technology.
In web dynpro ABAP we follow MVC(Model View Controller) architecture.
In this object oriented ABAP is used to provide background functionality. Here, your ABAP skills can be utilized to the fullest. Programming in web dynpro ABAP is different than conventional ABAP programming. Here we strictly follow MVC architecture in terms of controller interface. Also there are many wizards available so that we can directly pick the code from wizards.
e.g We can call BAPI through a service call in web dynpro application. Thus automatically backgroud code for BAPI execution will be generated.
To start with Web dynpro ABAP you can try following tutorial:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a282c952-0801-0010-1eb5-87953e036712
You can start with tutorials and all. There are around six tutorials in SDN library.
