Webdynpro ABAP and Light Speed Rendering Engine Performance reports

Hello,
We will be applying the NW EhP1 and ERP EhP4 in November this year.
I am very much excited about the new Lightspeed rendering technology that SAP has delivered with Webdynpro ABAP.
Has anybody installed this already and can you comment about the performance of Webdynpro ABAP AFTER activating this new rendeing engine?
regards,
Atul Kulkarni

We have implemented the EHP1 for NW 7.0 and ERP EHP4 back in May 2009. The performance of web dynpro applications is much better with the new rendering engine. The new name is living up to it's character of speed of light.
The usability of the application has increased with the new trade show plus theme. For example pink background for fields with errors. Access Keys and Hot Keys are very useful, specifically if you are migrating legacy applications from systems/languages which rely heavily on access keys.

SAP recommanded WebDynpro ABAP Startup parameter

Hello everyone
We have a webdynpro abap application where the display at the browser is very slow.
The problem is not at the application itself. All table read are very quick. But when displaying the record to the browser it is deadly slow.
1000 records:
Read time less than 1 second.
Display time to the browser 28 seconds.
All the code has been optimized to reduce reading time. But the time required to display is killing all users patience.
I would like to know if someone has any kind of documentation indicating SAP recommandation of the startup parameters, at the WAS level or at any levels.
Is there any tools available to trace where is the bottle neck? Why it is so slow to display?
So far, the debugging tool just indicates that all database read section are working with great efficiencies.
we tested the application using windows explorer 7 and firefox 3.5. Same result with both browsers.
any suggestino wil be highly appreciated.
Regards
DSTJ

Hello Thomas
Thank you for your reply.
At the browser level, the display has been set to 10 rows only.
The selected record at the server level is 1000 records. But only 10 rows are displayed at a time.
I am trying to find any documentation related to parameters that have to be setted to have optimal performance using WebDynpro ABAP application.
Related to my comment where the information was refering the webdynpro java was related to the Arun P. link not your post.
The WD_TRACE_TOOL give some information. Unfortunatly I don't know how to use it. I need to play with it.
You refered to CTRLALTSHIFT+P. I don't know where to perform those key stroke. I tried at the browser level, at the SE80 level without success. So, I didn't understand that part.
If you can guide me further, it will be highly appreciatted.

Poll: Development in ABAP Objects / Webdynpro vs. classical Dynpro

Hey there ABAP developers,
I just want to ask if you can give me one or two minutes of your attention for two poll questions.
At the moment I´m writing my master thesis about the development of a monitoring tool in ABAP. One of my bigger chapters is about the decision, which programming paradigm should be used for new development projects in SAP. And another important one is about WebDynpro vs. classical Dynpros.
Because of the fact, that I can´t create any polls in here, I just started this discussion and hope for many replies .
It would be very nice if some of you could give me an answer to the following questions (only 2 ), so that I can maybe use the result of this poll in my master thesis, if there are enough responses.
1. What percentage of new development projects are you developing in ABAP Objects? (Not to be considered small reports that just runs for only one time)
     A. 0 %
     B. less than 25%
     C. 25% - 49%
     D. 50% - 75%
     E. more than 75%
2. Which GUI technology do you prefer?
     A. Classical Dynpro
     B. WebDynpro
     C. Business Server Pages (BSP)
     D. others (please mention)
I want to thank you in advance for answering the questions,
Best regards,
Christoph

Hi,
Present SAP Implementation projects are very rare, maximum projects are support and up gradations only .
If they want Implement the SAP newly , defiantly they should creating ABAP Objects.
Why Because ABAP Objects are Object Oriented Concepts, so, for future reference and re usability..etc .
Now Come to the First Quetion.
if it is implementation project   ABAP Objects are 25% - 49%.
if it is Support project ABAP Objects are 25%
Now Come to the Second Quetion.
Depend upon Reqmnt, but Most of the Applications are Webdynpro . i.e 70%.
Remaining 30% All ( BSP and GUI ....Etc..)
This is my opinion.

If I understand you correctly you are saying that you called some standard SAP functionality from within your custom Web Dynpro Applicaiton and now you would like to know what authorization objects will be triggered when you run you WDA. Is that correct?
You could use SU24 similar to way that you search for Tcode assignment to authorizations. Choose External Service as your Type of Application. Then choose WEBDYNPRO as your type of External Service. Then supply the application name of the WDA application. However this doesn't sound like it will give you exactly what you want - searching for all auth checks within an application. Maybe I'm not fully understanding the correlation you tried to make to SU24.

Webdynpro ABAP content authorization object in SAP portal ?

Hi
We are on EHP 6.06 , we have an authorization problem in sap portal for the webdynpro abap content. our standart users got the error "page can not be found" for the services provided from webdynpro abap. when I assign the user to administrator group in sap portal the services working fine. I also checked the SAP ERP roles no problem is there. I guess I should create a new portal role for them cause its the only difference between users who can reach or not but have no idea what to put in it in SAP portal. Any idea ?

in portal content directory => double click on the Content provided by sap folder. Than you should have a dropdown somewhere where you can select "Authorizations". You should add the group endusers and check the checkbox.

Webdynpro ABAP or Webdynpro Java?

Hello experts.
I want to learn to develop WebDynpro's
Do you which of the two tools do you recommend? webdynpro java or webdynpro abap.
Greetings

Hi Lupe ,
Although both technologies have same functionalities but even then they are not identical.
Following are some of the differences:
Language :- First difference is the programming language used as the names Webdynpro ABAP and Webdynpro JAVA reflect. In ABAP Webdynpro, along with ABAP coding, RFCu2019s are also supported via Service call. Unlike Webdynpro ABAP, we cannot do ABAP coding in Webdynpro JAVA. Instead RFCu2019s and Web services are created and used in it to serve this purpose. In addition to Web services and adaptive RFC, Java Beans is another model supported by Webdynpro JAVA.
Design Time Environment :- Webdynpro ABAP requires ABAP Workbench (SE80) while SAP Netweaver Developer Studio is necessary for designing Webdynpro JAVA applications. So, additional installation is required. This studio reduces the development effort and utilizes some visual tools for creating components which can be reused.
Storage :- Applications developed using Webdynpro ABAP are stored centrally in ABAP server whereas in case of Webdynpro JAVA, the code remains on the client machine that is developed using a tool called Netweaver Developer studio. So, due to the powerful version control system of Webdynpro ABAP, the load removes from the development machine which is not possible in case of Webdynpro JAVA.
Skills Required :- For Webdynpro ABAP, a developer should have knowledge of ABAP programming, Development tools, Database concepts, ABAP Objects. However, Webdynpro JAVA requires skill set comprising java programming, java development tools and object-oriented concept.
Performance:- Large scale applications that involve large number of web users canu2019t work well on ABAP server. So, for robust and scalable applications, Webdynpro JAVA is preferred because of powerful J2EE server as proved by Sun Microsystems. However, small-scale or applications involving small or medium users can go well with Webdynpro ABAP. Thus, performance varies depending on the number of web users and one can choose ABAP or JAVA accordingly.
So the decession is that its totaly based on your available skillsets and your scenario to be implemented.

Translation of non-ABAP objects

Hello colleagues,
I know that SAP provides special Translation Environment for translation of ABAP-objects (TX SE63 etc.). But what about translation of non-ABAP objects? Could be SE63 suitable for this task or it can be performed only via translation xlf files (SAP NW Developer Studion and so on)?
Regards,
Arkadiy

Hi Prakash,
firstly thank you for you reply.
Secondly I know about three main categories of non-ABAP objects but I haven't an information about what is it certainly? So there are at least two questions in my opinion:
1) Could it be suitable to translate Java objects or WebDyn Pro Java objects?
2) If yes, how it can be suitable for it? Because I know how I can translate Java or WebDynpro via NW Developer Studio, but I don't know how it can be possible via SE63.
Really I can't find any helpful information about translation non-ABAP objects via SE63.
Could anyone help me in my questions?
Regards,
Arkadiy

[HELP] Webdynpro Abap application keeps refreshing on Portal

Hello Gurus,
Im facing a really annoying and weird problem, i've created a screen exit on the transaction IW21, on this screen i have a custom container, and im using the class cl_gui_html_viewer to show off a webdynpro abap application on this container. If i access IW21 via SAP GUI everything works fine, no problema at all. But once we've published this transaction IW21 on Portal something very weird happened, the webdynpro application keeps refreshing on every action done in the screen. I've entered on debug mode to verify if the program is performing the code to create the html object again, but the program pass in the perform only once. An example: when i click in save the program pops a screen to choose some characteristics and i can clearly see the webdynpro application refreshing under this screen, like if i press F5 on browser. As i said everything goes pretty much fine in SAP GUI, but in Portal keeps refreshing.
Anyone have any idea how can i solve this?
Regards,
Rafael

Are you calling ITS transaction and Webdynpro application is within this transaction?

Adding leading zeros in abap objects.

Can anyone explain me
1. How to add leading zeros to a field in abap objects.
For eg:
data: dmb(6) type c value '123456',
actually the output value of c should have leading zeros added to it for length 16.
i.e '0000000000123456' . If the length of dmb is less than 16 then leading zeros should be added to that value to make it 16 as length.
Please tell me how to do it in ABAP Objects.

Hi Camila
Try to use the statement
DATA: ALPHABET(15) VALUE ' ABCDEFGHIJ',
 M1(4) VALUE 'ABCD',
 M2(6) VALUE 'BJJCA '.
SHIFT ALPHABET LEFT DELETING LEADING M1.
The field
ALPHABET
remains unchanged.
SHIFT ALPHABET LEFT DELETING LEADING SPACE.
The field ALPHABET now has the following contents:
'ABCDEFGHIJ '.
SHIFT ALPHABET RIGHT DELETING TRAILING M2.
ALPHABET now has the following contents:
' ABCDEFGHI'.
IN CHARACTER MODE
Effect
This is the default setting (see above), and the addition is therefore optional.
Note
Performance:
For performance reasons, you should avoid using SHIFT in WHILE loops.
The runtime required to shift a field with length 10 by one character to the right or left requires about 5 msn (standardized microseconds). A cyclical shift requires around 7 msn. The runtime for the ...
LEFT DELETING LEADING
... variant is around 3.5 msn, for ...
RIGHT DELETING TRAILING
... around 4.5 msn.

ABAP list processing statements in ABAP Objects

Hi,
Based on the Online help "The ABAP statements used for list processing are not yet fully available in ABAP Objects".
Is there any chnage planned about this for the next WAS release?
Thanks,
Peter

Hi Peter
I believe, most of the measures taken are for some compatibility and performance issues. So, there is no need to expect great changes about this.

How to insert the image or logo into the table as a field in webdynpro abap

Hi Friends,
Please tell me how to insert the image or logo into the table as a field in webdynpro abap.........

Hi Alagappan ,
In your view layout you take table UI element and then you bind it with some context nodes.
The attributes of your nodes comes as a field.
Now in these fields you can set various properties and image is one of them.
Go to ->
1. View Layout -> Right Click on ROOTUIELEMENTCONTAINER -> INSERT ELEMENT -> TABLE
2. Right click on table -> Create Binding.
Here you have to bind it with the appropriate context node.
You will get two properties here
a- Standard Cell Editor :- ( make it image )
b- Standard properties :- ( If required set image properties ).
3. If you want put image from out side then import it as a mime object and set the source of your table field ( used as a image )
also have a look :-
[Image Properties|http://help.sap.com/saphelp_nw04/helpdata/en/f3/1a61a9dc7f2e4199458e964e76b4ba/content.htm]
Hope this will solve your problem.
Reply if any case of any issue.
