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.
Regards
DSTJ

  • How to Generate New Version of Enhancements done to Std WebDynpro ABAP obj

    Hi Experts,
    We have enhanced a SAP Std WebDynpro ABAP component (HAP_DOCUMENT_BODY) using Enhancement framework provided by SAP. Multiple enhancements were done on the same component for different requirements. Now, under the Enhancement Implementations folder of this component, you can see 5 enhancements of the component each referring to the 5 different changes done (most of the changes were done to the same view ).
    These changes has now been transported to the Quality System. Now, the client wants one of the changes to be removed. I am not sure of the impact of removing, for eg: the 3rd enhancement,  on the other changes done as multiple enhancements were done in a mixed manner.
    What i want to do is to generate a new version of WebDynpro component on Dev which has all the enhancements done so far using Utilities -> Versions -> Generate new version. Then try to delete the 3rd enhancement folder, so that if something goes wrong, I can always revert to this newly created version on DEV which has all changes available.
    Questions:
    1)  Before that, I would like to know if I can generate versions of the enhancements done of WebDynpro ABAP using enhancement framework by using Utilities -> Versions -> Generate new version ?
    2) If yes, I want to generate one version which has all the enhancements done so far using enhancement framework. For doing so, where should i do the click or selection (Is it Std Main Component or is it Enhancements in the enhancements folder-if so, there are 5 of them, and which one??) before i go to  Utilities -> Versions -> Generate new version. I am not clear where i should select or keep the cursor selected on before generating a new version? 
    Please guide with step by step details.
    Thanks,

    I have moved this post to the HTML5 layouts forum, which is more appropriate.
    I am guessing you are using Rh11 as you have a trial copy. I have some instructions for Rh10 and the only difference should be the script used. See the contact page on my site and request those details. Include a link to this thread.

  • Webdynpro ABAP integration with Flex

    Dear All ,
    We are trying to integrate the Flex with ABAP WebDynpro. On the front end there are a set of check-boxes and whenever the user selects one or more check box , we need to make a note of this selection and save this to the database. Data in FlexBuilder is getting stored as ArrayCollection with two columns label and selected.
    We need to integrate the same into SAP using WebDynpro ABAP. We have created a datasource to read the values. Even after giving the identical names in webDynpro the data is not getting populated.
    If any of you has worked on a similar requirement earlier, please revert back .

    Problem is when I am executing with enduser portal WWID's (i.e. WWID's are also defined as sap
    user), 'WebDynpro ABAP Application scenarios' giving me dump in screen & in ST22.
    Pls guide me what roles or authorization we need to assign to user ID's

        The current ABAP program "CL_WD_ADOBE_SERVICES==========CP" had to be

        come across a statement that unfortunately cannot be executed.
    Error analysis
        An exception occurred that is explained in detail below.
        The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
         caught in

        Since the caller of the procedure could not have anticipated that the

        The reason for the exception is:
        You attempted to use a 'NULL' object reference (points to 'nothing')
        access a component.
        An object reference must point to an object (an instance of a class)
        before it can be used to access components.

  • SAP Webdynpro ABAP Application Caching Issues

    Hi All,
    We have developed custom applications using Webdynpro - ABAP, using FPM and accessing those applications through SAP Netweaver Portal 7.0. I have deactivated all the caching techniquies in Portal @ iview level and Page level, Portal Runtime and ContentFetch side, But still causing the same problem.
    I have a doubt, wether this is happening because of SAP Logon Caching @ SAP WAS system level. I have checked the SSO parameter settings in RZ10 Profile parameters. Our basis people have set both accept and create parameter value = 1. Is this causing issue?
    Or Is there any other settings which is required to do in Portal or SAP system level. Please let us know , really appreciate your value suggestions and help.
    Please find the below links, which im referring to...

    Hi-
    (though the url seen in the application in se80 in the webdynrpo abap component does not have workitem id paramter)
    It is required to have a parameter WI_ID (as an Application parameter) in your WDA. And via this Application parameter WDA will receive the workitem id, when the task is exceuted from UWL (provided configuration is done in swfvisu)
    Could you confirm, there is no Application parameter (WI_ID) in your WDA?
    It picks the same workitem id everytime. I tried doing this with a couple of different user ids. but I cant figure out from where it picks this particular workitem id
    If you defined WI_ID in Application parameter and there is an option to provide value and it seems, you have defined some value over there or other way might be in your method (inbound plug), you may gave default value to WI_ID in the parameter
    If your application is working properly from UWL and for testing purpose, you could put a breakpoint and change the workitem id, when executing from se80

      l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).

  • For sap mdm do i need to know webdynpro abap or java

    hi
    i want to learn sap mdm, then do i need to have knowledge in any of  following languages?
    1. webdynpro abap
    2.webdynpro java
    3. normal java( core java/j2ee )
    4.  normal abap
    thanks
    akhil

    If you are using ABAP APIs then normal ABAP knowledge will come in handy
    If u want to connect your MDM server to a portal system, then Portal knowledge will come in handy
    Even the basic MDM scenarios are generally done by using Exchange Infrastructure
    so basic knowledge of that is essential

  • 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.
