SICF Access for Web Dynpro Development

Developer wants access to SICF to be able to test any Web Dynpro Development. Currently no developer has access and Basis only gives access when requested - and only for short time. I believe developers should have access. Wondering how others have this setup. Thanks!

> If a developer creats an app via SE80 - which does the same in ICF for the service - then SICF access is required.
Are you sure? Or is the tcode check only appearing somewhere in a trace?
If that is true, then ICF service developers will anyway be able to start SICF directly. Please check the coding location of the check from the trace, if it is calling FM AUTHORITY_CHECK_TCODE (which I suspect it is...) then verify in SE97 that an SE80 developer can use (limited, coded...) SICF functionality from other contexts without starting it directly.
What you can also do is protect the ICF services using the authorization group concept (including those you are not using...). If the developer wants to use one (in a new development) then it should be released for them by granting them access to it (authorization object S_ICF_ADM in their role) for development work and then ideally object S_ICF added to the service user they are using for development as well. If they are developing the role for the application together with the application coding development (this is the ideal scenario in my opinion for a knowledgable developer) then give them that access as well in PFCG for the role they are developing.
I think it can safely be said that most developers can be trusted, but also to do stupid things though... and they enter their own user ID in the connection data..
That is a reality. If you trust them and train them and collaborate with them to improve security - then they will be your best friends and understand more about security as well (to protect themselves from their own user ID's...).
This is a very interesting topic. Thanks for raising it.
Cheers,
Julius
ps: I don't like posting links, because I see it as an insult to the person who asked the question as not having done a search and not knowing what they are talking about. But for the benefit of those who use the search and find this thread... please read this documention (or the one which is relevant for your release - I choose a reasonable release level...).

SAP tool to estimate time for web dynpro development project

Hi,
Is there any standard SAP tool available to estimate time for web Dynpro development project?
Thanks and Regards,
Deepti

Hi Deepti
An implementation of Webdynpro based UI could be estimated by a 'standard' technique like any other U:
1. Try to count the number of views/screens/popups in your application. The estimation time will be proportional to the quantity.
2. Try to count the number of external interfaces would be used in the application. For example, quantity of necessary BAPI invocations (RFC), quantity of Web-service invocations or EJB calls. Also quantity of native JDBC queries if any.
Test = Nviews x Hview + Nint x Hint, where Hview & Hint time in hours for average implementing of one UI view and time for adding of average service invocation.

Time estimation for Web Dynpro development

Hello all,
i would like to know if someone could tell me how much time do we have to estimate when using web dynpros to recreate R/3 transactions (with the convert tool) ?
In fact we must make an offer for a customer and would like to use Web Dynpros (since this customer wants that all developments are J2EE based and not related to R/3).
Since we don't yet have any experience with this, it's not easy to make an estimation of the effort that it would take.
So if you know what is the average time to make an R/3 transaction Web Dynpro enabled, please let me know.
Thank you in advance,
Xavier

Hi Xavier,
what i know so far about the convert tool is, that it allows to convert classic ABAP dynpros to Web Dynpro, but not between the ABAP Web Dynpro runtime and the Java Web Dynpro runtime.
Among other things, the PAI and PBO modules of the classic dynpro are reused including possible input validations which may directly access some tables of the ABAP dictionary.
Since all these things are not at all directly accessible by Web Dynpro for Java and the J2EE engine in general, the only thing, that might be transferrable IMHO is the layout information (buttons, inputfields...).
Regards
Stefan

508 / Accessibility for Web Dynpro

Hi,
Does web dynpro support accessibility / 508 ?
As I have read and heard on teh techEd the web dynpro stack9 will support this, so I can set the property sap-accessibility=x resp. accessibilityDescription="testtext".
Also in the thread "Keyboard access to UI Element"
Posted on: Jul 29, 2004 10:27 PM, by user: Armin Reichert
Accessibility has been addressed and will be supported in the production release.
So I have download the WAS 6.40 as a 90 days test licence. But in the NW Dev. Studio there is no such a attribute for the GUI elements. Do I have to upgrade? But how?
Regards Ralph

Hi Armin,
thanks for the quick reply.
What I mean is, that in the presentation PRTL205 of the TechEd2004, on page 30 there is a screenshot from the NW Dev. Studio where you can see a property 'accessibilityDescription' for a GUI Element. Is property is not in the current NW Dev.Studio which you can download from SDN.
You know, if there is a 'newer' IDE than the one you can download?

Ralph

Web Dynpro Development Components missing for MSS

Hey Guys...
The following BPs are installed on our landscape:
○       Business Package for Manager Self-Service (SAP ERP) 1.3
○       Business Package for Common Parts (SAP ERP) 1.3
○       Business Package for Project Self-Service (SAP ERP) 1.0
○       Business Package for HR Administrator (SAP ERP) 1.1
The ECC is EHP 3, SP 14 and EP is 7.0 SP 14
I've been trying to set up iViews for MSS but I see that all Web Dynpro Applications specified in the technical information of iViews are missing. I searched for Web Dynpro Development Components in the EP and all MSS related WDC are just missing.
According to SAP Help Documentation (http://help.sap.com/erp2005_ehp_03/helpdata/en/76/77594d165144a1a9bff9aae1e26b26/content.htm) these are required:
Web Dynpro Development Components:
○       PCUI_GP
○       MSS
○       SAP_PSS
Where can I get them??? Is it possible our basis didn't install the right Business Package?

Seems you have got right business packages, though have a look at note [1303362|https://websmp230.sap-ag.de/sap%28bD1lbiZjPTAwMQ==%29/bc/bsp/spn/sapnotes/index2.htm?numm=1303362] to confirm dependency.
"but I see that all Web Dynpro Applications specified in the technical information of iViews are missing."
Well this could be because of errorsome business package deployment, you can still check list of deployed components from SDM and if there is any error log for deployement, you should try to deploy them again(update existing components).
Hope this helps. If not then probably you should go Content Admin - WebDynpro and see list of application listed under MSS.. if those referred applications are available then try to execute them.
And last one.. if you "think" they wont run.. or you have actually tried to run MSS and none of applications are working. you should be able to run standard package without any major configuration chanegs.. so give it a go.. and see if you encounter any error.
Cheers

Accessibility in Web Dynpro

I've been asked to switch on accessibility for web dynpro. These are the steps I've taken so far but they don't seem to have had any effect:
1) added the WDACCESSIBILITY parameter to an application with a value of X.
2) The PDF document 'Developing Accessible Applications with SAP Netweaver', in section 4.4.2, tells me to add the following to the end of the url: '?sap-accessibility=x'. I'm not able to do this on the application properties as the url field is greyed out. After launching the application I added it to the end of the url but it did not seem to make any difference...though I believe it may be that I will not see anything until I try it with a screen reader ?
3) OSS Note 1412833 (though on a slightly different release to us) talks of having to make changes to table WDY_APP_PROP_DEF in order to get the WDACCESSIBILITY parameter to work. I've done this and I still do not see any change when trying 2) above.
Does anyone out there have experience in this area that can provide me with some advice ? Am I following the correct steps (am I missing anything ?) and should I be seeing a difference in the aplication or should I only expect to see a change if I use a screen reader ?

Hi,
Check that you have added the correct parameters "sap-accessibility=x"
Also tooltip will only be visible when there is a tab\focus on the UI element.
Also you can check for accessibility in debug mode by adding param
sap-accessibility=x&sap-accessibility-debug=x
After that press CTRLALTSHIFT+A, A yellow coloured status bar will appear at the bottom of your window which will show you the accessibility tooltip for that UI element whenever that UI element gets focus
Check the [snapshot|http://picasaweb.google.com/lh/photo/j2EDy-AXZfL5Fn-ZaZZUVQ?feat=directlink]
Also you can have a look at following documentation
http://www.sapdesignguild.org/resources/acc.asp
http://www.sapdesignguild.org/resources/Accessibility_Guideline_WebDynpro_external_Version.pdf.
Also check your IE version should be IE 6.0 or above.
If all that doesn't helps than time to raise a CSN ticket.

Whats the initial DC for Web Dynpro DC from scratch

Hi,
I want to develop a Web Dynpro Development Component from scratch. So what is the default/initial DC that I have to import from DTR/JDI?.
Thanks,
Raj.

Hi,
rather sparse information... anyway if you start with the "Local Development" configuration in the IDE all required DCs should be part of the NWDS installation.
Otherwise you need to have a track configured that contains SAP_BUILDT, SAP_JTECHS and SAP-JEE. Those three SCAs contain all DCs required for Web Dynpro development.

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
 I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
 procedure"
 Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
 signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

Coding standards for Web dynpro ABAP

Hello all,
Can anybody please help me by providing the code review checklist for Web dynpro ABAP?
Thanks and Regards,
Rohini Shankar

Hello friend,
WebDynpro     *
1     Do not implement Data intensive operations in UI layer
2     Avoid database selects in the WebDynpro code.Use the corresponding BAPIs ,Methods
3     Are ABAP OO Classes like Assistance class are being used for application coding ?
4     Are Windows/Views only used for the sole purpose of hosting views and context?
5     Are a reasonable number of views put in a single WD Component instead of creating multiple WD Components ?
6     Unneccessary usage of dynamic programming and dynamic component avoided
7     Are singleton nodes used in case of nesting in the context ?
8     Is deep nesting of containers, Groups and Tabstrips avoided ?
9     Is the UI element TreeByKey or TreeByTableNestingColumn used instead of the Tree UI element ?
10     Is the checkbox "Accessibility Checks Active" ticked in the WD Component properties
11     Are the WD Component Instances deleted when no longer needed (IF_WD_COMPONENT_USAGE=>DELETE_COMPONENT)
12     Are the OTR texts defined for all the labels, texts(where ever appropriate) in properties of all the UI elements
13     Has the Generation limit been checked for all the components developed
14     Sufficients commets are written at the beginning of every major block to explain the processing logic.
*Error Handling     *
1     Is SY-SUBRC checked after CALL function modules
2     Use Assertions if you face unexpected errors which usually never ever occur!
Extended Check and Clean Up
1     Have following been removed :
     ·      Unused variables
     ·      Unused text elements
     ·      Unused tables from TABLES statement
     ·      Commented out parts of the code
     ·      Code segments which do nothing
2     Is extended program check completed and all errors/warnings removed
These are the things which i used for my project.

Want docs for Web Dynpro ABAP

Hi All ,
Can anyone please send me the Docs or link for Web Dynpro ABAP .
Thanks in advance
Rahul

Hi,
Web Dynpro ABAP
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/db22242d-0701-0010-28a2-aeaa1fefd706
Also, I have the official Web Dynpro for ABAP documentation. Please let me know if I should send it to you.
Hope that the following also helps you.
Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web
applications in the ABAP environment. It consists of a runtime environment and a graphical
development environment with special Web Dynpro tools that are integrated in the ABAP
Workbench (SE80).
Web Dynpro offers the following advantages for application developers:
? The use of declarative and graphical tools significantly reduces the implementation
effort
? Web Dynpro supports a structured design process
? Strict separation between layout and business data
? Reuse and better maintainability by using components
? The layout and navigation is easily changed using the Web Dynpro tools
? Stateful applications are supported that is, if the page is changed and the required
data remains intact so that you can access it at any time throughout the entire
application context.
Note that stateless applications are not possible.
? Automatic data transport using data binding
? Automatic input check
? Automatic operation of the Web Dynpro application using the keyboard
? User interface accessibility is supported
? Full integration in the reliable ABAP development environment
Web Dynpro Architecture
Definition
Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
The Web Dynpro model is based on the Model View Controller paradigm, and has the
following features that build on the classic dynpro model:
? Clear separation of business logic and display logic
? Uniform metamodel for all types of user interfaces
? Execution on a number of client platforms.
? Extensive platform independence of interfaces
Structure
Metamodel Concept
Web Dynpro provides support for developing Web representation of a business application.
You use specific tools to describe the properties of a Web Dynpro application in the form of
Web Dynpro metadata. The necessary source code is then generated automatically and
executed at runtime. In addition to the events offered by the framework, you can also define
your own events for a Web Dynpro application. However, the event handling must always be
programmed in separate source code areas which are executed automatically when the event
is triggered at runtime.
In Web Dynpro, each user interface is always made up of the same basic elements. These
elements of the metamodel can be statically declared using Web Dynpro tools.
It is also possible to implement elements of the metamodel at runtime and to change them or
reintegrate them at runtime. Using these implementations, you can make any changes or
enhancements to a user interface that has been created by declarative methods by
generating new interface structures at runtime.
This means that you can combine declarative processes and the implementation of source
code.
Graphical Development Tools
To support this declarative concept, both the SAP NetWeaver Developer Studio and the
ABAP Workbench contain a range of Web Dynpro tools. You can therefore generate a large
proportion of a Web Dynpro application using the tools provided, without having to create your
own source code. This applies to the following parts of the application:
? Data flow between the front end and back end
? Layout of the user interface
? Properties of user interface elements
The Web Dynpro tools enable you to create source text areas manually within generated
source texts. These areas are not changed if the source code is regenerated.
Separation of Business and Application Logic
Using Web Dynpro enables a clear separation of business logic and display logic. A Web
Dynpro application runs on the front end and has local or remote access to the back end
system via a service. This means that the display logic is contained in the Web Dynpro
application, while the business logic and the persistence of the business objects run in the
back end system. The following options are currently available for connecting Web Dynpro
applications and the back-end system:
? An interface generated using adaptive RFC, through which BAPIs of an SAP system
can be called
? An interface for calling Web services
? A self-generated interface
The source code required for connecting the Web Dynpro application can be generated
from a UML definition of the Web Dynpro interface. A UML definition can be imported
into the Web Dynpro tools as an XML file.
Conversion of the Model-View-Controller
Conversion of the Model-View-Controller Programming Model
Every Web Dynpro application is structured according to the Model View Controller
programming model:
? The model forms the interface to the back end system and thus enables the
Web Dynpro application access to data.
? The view is responsible for the representation of the data in the browser.
? The controller lies between the view and the model. The controller formats
the model data to be displayed in the view, processes the user entries made by the
user, and returns them to the model.

Creating Room Instance from Web Dynpro Development Component

Hi Experts,
I would like to instantiate a Room Instance based on a pre-created Room Template from within a Web Dynpro Development Component. I had a look at the Collaboration Rooms API Cookbook, which provides all the code examples I need, but which asks that I import the following classes:
import com.sap.ip.collaboration.room.api.IRooms;
import com.sapportals.portal.prt.runtime.PortalRuntime;
Problem is I don't have and can't find those libraries. I am developing in a track on the DTR and all solutions that I have found to the problems thus far require me to import a local jar file. Surely I should rather import a Software Component with the required library into my project? Does anyone know what the name of this Software Component is or what the correct way is to do this?
Also, a somewhat related problem. If I want to create a Room Instance from an Application Service, how would I go about doing this. Unlike with a Web Dynpro project, I can't setup the build path or Used DCs, so how will I gain access to that library?
Thank you,
JP

Beevin, thanks for the reply.
I am aware that adding the jars manually to the build path is a possibility, but isn't this a local only solution? What I mean is, lets say I do this and check the code into the DTR - surely the code won't compile on my co-workers' machines as the paths to the jar files are different for them? Unless you mean to somehow add the jar file from the server, in which case could you please elaborate on how to do this?
This still doesn't solve the application service problem, does it? How can I access those library from the CAF DC?
Thanks

Large Production Web Dynpro development

Everyone knows how to develop in ABAP in a way that works in team environments and provides reuse, but this is not clear within Web Dynpro. I'd like to see a tutorial or overview of how large Web Dynpro projects with multiple developers should be structured in terms of using DTR, interfaces between components, database design, etc. Until DTR becomes available, all Web Dynpro development is just "playing around", but when it gets here, I hope SAP can provide an overview of the right way to develop.

Hi Matt,
i would like add the following remarks to your suggestion:
1. Availability of DTR
Nearly nobody, except SAP internals and ramp up customers have a DTR available today. So the prerequisites for 99.9999% of all other SDN users to follow the steps in a tutorial (or overview) don't exist. This is crucial IMHO, because you have to start with DTR activities to be able to do anything.
2. How to get DTR running
Configuration and efficient usage of the DTR (there are minimum 4 possible development scenarios) is enough to fill a big, at least 3-hour tutorial without even having touched Web Dynpro (let's call it Part 1).
3. Backend access in a productive scenario
is the next point. What would you like to see included? EJB (with BMP or CMP?), JDO, ABAP (Adaptive RFC and/or JCA?), Web Services? Again, this is enough to fill an own tutorial (let's call it Part2).
4. Design and usage of Web Dynpro
and some other, for a full featured article necessary, types of Development Components. This is rudimentary documented in the NW documentation, but who of the Sneak Preview and other users work with them so far? What are best practices and common traps designing them (let's call it Part3).
And last but not least...
5. The Composite application framework (CAF)
and especially the promised features of it's designer and the generation framework behind it will probably disprove most if not any of the working practices (at least concerning point 3) mentioned in a tutorial.
The CAF is the so far missing piece in the puzzle, because it connects services of any type between each other and to the presentation layer (including Web Dynpro UI patterns nobody used upto now) based on metadata models (let's call it Part 4).
So from my point of view we should think about reducing the requirements what should be covered by the upcoming article/tutorial to the (real world) work with DCs.
Best regards
Stefan

Web service in Web Dynpro development Component

Hi All,
I have created a web service in SAP GUI and I have saved the WSDL file on my local PC.
Now when I create a web service model in a simple web dynpro project it works perfectly.
But when I do the same in a web dynpro development component; as soon as the web service model instance is associated with the activity in the DTR my application get hanged. I have to quit my NWDS. When I reopen NWDS my application shows following errors:

Hi Sidharth,
Which version of NWDS you are using. I was facing the same problem with SP16 sometime back.
I did find a workaround to do that. See, whenever you will create the WS Model in Web Dynpro DC, it will ask you to add some file in DTR..right!!........ do one thing press "Cancel" or "No" there. Then studio will ask one more time to add the files, in different dialog box though. Add the files from the second dialog box rather than the first one.

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in
Kind Regards,
Owen
