Updated data in a web dynpro application

hi
when we develop a web dynpro application using a model from an R/3 as a backend access system , how is the data updated in the application, in the portal whenever there is a change in the source OLTP data tha we used?
thanks in advance

Hi,
Do you want to change the message server name thriugh coding then use the below code.
Store the message server name in a customizing table.
use the below code to replace the MS name:
DATA    lv_temp_str TYPE char255.
DATA    lv_split1 TYPE char255.
DATA    lv_split2 TYPE char255.
DATA : lv_string TYPE string,
          lv_application TYPE string.
DATA    lv_dns_str TYPE /mrss/t_rm_dns_str.
CALL METHOD cl_wd_utilities=>construct_wd_url
    EXPORTING
      application_name = lv_application " webdynpro application name
    IMPORTING
      out_absolute_url = lv_string."url of the application.
lv_dns_str = message server name form the customizing table
lv_temp_str = lv_string.
SPLIT lv_temp_str AT '//' INTO lv_split1 lv_split2.
CLEAR lv_split1.
lv_temp_str = lv_split2.
SPLIT lv_temp_str AT '.' INTO lv_split1 lv_split2.
lv_temp_str = lv_split1.
REPLACE lv_temp_str IN lv_string WITH lv_dns_str.

Exchanging data between a Web Dynpro application and SAP Web Shop

I'll try to keep this as clear as possible:
1) We have the SAP Internet Sales system running, which has a series of Business Object classes and corresponding Backend Layer objects that can return data from several sources.
2) We are able to create our own Backend Layer objects that would return data from a component called IPC, which is a Java component.
3) I would like a Web Dynpro application to retrieve data from this backend layer object, but I am not experienced enough with Java to know if what I want to do is possible. I don't think that I can use JCo, because I am trying to get a Java component (class?) in Web Dynpro to access a Java class remotely.
4) I think I am asking is this: is there a way for a Java to Java connection to be created, much like Web Dynpro can use JCo to connect Java to ABAP systems?
If this is a glaringly obvious question to Java programmers, my apologies!
- Tony.

Somebody on another forum recommended using RMI. Which would be the better option in terms of ease of implementation?

How to send data from a web dypro application using workflow

Hi All,
I am working on a web dynpro application where the user will enter the header and item details for a FI document to be posted. Once the user enters the data the workflow should initiate and should also send the data across to the approver to approve. To initiate the workflow I am using the function module 'SAP_WAPI_START_WORKFLOW' and it's working fine and generating a uniquw workflow item id. Now my main concern is how to send the data across from web dynpro application through the workflow. I have my data in three internal tables: 1. header table. 2. G/L table and 3. Currency table, I am capturing all this data from the web dypro screen entered by the user. Right now I have the following code in my web dypro application.

Dear Colleague,
You have different method to send parameters to Workflow.
1. Method
Container Set Element
DEFINE SWC_SET_ELEMENT.
CALL FUNCTION 'SWC_ELEMENT_SET'
    EXPORTING
      ELEMENT   = &2
      FIELD     = &3
    TABLES
      CONTAINER = &1
    EXCEPTIONS
      OTHERS    = 1.
END-OF-DEFINITION.
Set the data into Workflow container
    SWC_SET_ELEMENT IT_CONTAINER 'parameter1' lv_parameter1.
Start the Workflow
    CALL FUNCTION 'EWW_WORKFLOW_START'
      EXPORTING
        X_TASK          = 'WS90000001'   " your wf
      IMPORTING
        Y_WORKFLOW_ID   = WF_ID " your workitem id
      TABLES
        X_CONTAINER     = IT_CONTAINER
      EXCEPTIONS
        INVALID_TASK    = 1
        NO_ACTIVE_PLVAR = 2
        START_FAILED    = 3
        GENERAL_ERROR   = 4
        OTHERS          = 5.
2. Method,
You can also add your parameters direly to a container,
DATA: lt_simple_container TYPE TABLE OF swr_cont,
        ls_simple_container TYPE swr_cont.
ls_simple_container-element = 'parameter1'.
ls_simple_container-value = lv_parameter1.

    EXPORTING
      workitem_id      = WF_ID " your workitem id
      do_commit        = 'X'
    TABLES
      simple_container = lt_simple_container.

Adobe form data not being retrieved by Web Dynpro application

Hi,
I have created an online interactive Adobe form embedded in a Web Dynpro ABAP application. The Web Dynpro application calls a function module to update data in SAP. My problem is that the ABAP code that was generated to retrieve the data from the Adobe form and call the function module does not retrieve the data if it has been typed into any of the input fields. Oddly enough, it does work if the data is entered by using the value helps that have been placed on the form.
I would appreciate any suggestions.
Thanks!
Russell

Use messageboxes on various events to find out when your value dissapeears.
If you´re not sure about the binding, you can always drag/drop from data view tab onto the layout and check the binding which the system generates for you. Just to make sure.

Example storing data in the default schema with a Web Dynpro application

Hi,
is there any example or tutorial for storing data in the default schema with a Web Dynpro application via SQLJ or Hibernate by using the default DataSource?
Thanks for Help,

Hi,
When you create the TAB-Strip object you should be able to set the default displayed TAB against the properties of the TAB-Strip.

Web Dynpro Application Deployment need server restart?

Hi Everyone,
When deploying Web Dynpro application on production environment, do we need to restart the sap portal system and server?
I have this issue that when ever we deployed new develop Web Dynpro application with new Abap Function module we need to restart our Enterprise portal production server. Is this really necessary. Is there other way to deploy Web Dynpro application with new Abap function module without restarting the server.
Please help,
Michael Mondelo

Hi michel,
for example , assume you imported a RFC bapi_flights from r/3 to webdynpro dc , and both rfc requests and webdynpro application is deployed to the development server and then moved to quality server.
now you have done some changes in the rfc bapi_flights i mean change in the structure .
case 1 : now with out reimporting the change to webdynpro application and you move the request to the quality r/3, your application dumps . because the structure change is not incorporated at your webdynpro DC.
case 2 : you have re imported the rfc incorporating the changes to the web dynpro applicaiton dc, now with out moving the structure changes request to the quality r/3 and you deploy the webdynpro Dc having the changes to your quality EP , still the applicaiton dumps because your appliction refers to the rfc with out structure change in quality r/3.
case 3 : you have moved the abap request having the strucutre change and also the webdynpro development component where the changes are also incorporated , now on moving both , your application might dump , because the meta data cache might have been not updated with the new structure change in the quality ep server. so you have invalidate the cache in the JCos you have used to import the rfc. or else on restarting the EP server , the new structure change will be updated in the server.
most of the cases Invalidation of cache works and in some cases you have restart the server fo the changes to update.

Passing a parameter while calling a web dynpro application on portal

hi
I am having a web dynpro application which retrieves data from R/3 system via RFC using Jco destinations define in the Portal.
Now we have different kinds of portals running on the same WAS, now I want the application to run which access data from different R/3 systems thru different JCo destinations.
I need to create a logic such that mu application runs fine on any portal with any Jco destination.
Is there any provision to achieve this.
kindly let me know about this.
Thanks and regards
kris

Gopi,
there's an parameter called "sap-wd-arfc-useSys" you can pass to the application, to change the used JCo-Connection (read more at http://help.sap.com/saphelp_erp2005/helpdata/en/f4/651741f163f023e10000000a155106/frameset.htm)
so, if you're running the WD-aaplication on <b>one</b> WAS and call it from different portals, you have to create three (or six with the META-connections) JCo-Connection on your WD-WAS.
In a WD-application you can access URL-Parameters with:
WDWebContextAdapter.getWebContextAdapter().getRequestParameter("<your URL Parameter-Name>");

Some User get this message also in test an development. What could be the reason?
Note: Nothing has changed in coding or context.....this error occurs without any changements
Thanks for your help
Best Regards
Martin

Hi,
May be you can put an external breakpoint in the method "_get_attribute_rtti"(of class CL_WDR_CONTEXT_NODE_INFO).
From that you can find out which attribute is causing the dump , and try to solve the issue . May be some data dictionary object is not transported to production.(Assuming that you have permission to put breakpoints in production system..:))

I want to editable description field in my web dynpro application

Hi expert,
The requirement is to make the Description field editable. However, the container for the dynpro only appears to allow for a certain type of action and is essentially used to display the Line Item details, giving no option to change the Line Item Description.
so i want to editable in this description field in my web dynpro application /SAPSRM/WDC_DOTC_PC_I_BD .
Kindly give me soulation ASAP.
Thanks and Regard's.
Vikash

Thanks for the reply.
The name of the view is V_PC_DOTC_ITM on which we have the records. On each line item there is a description field which is of type (LinkToAction). I want to enable user so that it can change the Description text (I will handle the action). Also, if you have any idea about updating the database table from here as it needs to be updated in BBP_PCPOS table.

The Web Dynpro Application 'XssMenu' has expired

Hi,
we implement an ESS Scenario, with One Enterprise Portal 6.0 SP17, a mySAP ECC 5.0 System with ERP2004 and a seperate server with a java stack, because our customer don´t want to install and use a java stack on their HR/ERP systems. They want to minimize the performance.
After some configurations, we get the startpage for ESS. If I click on a service like travel management it has no effect. If I click the second time, I got an error "500 Internal Server Error" with the message
The Web Dynpro Application 'XssMenu' has expired. Please restart the application either with the refresh button or click the following link XssMenu.
Same error comes, if I choose travel management in the second navigation level and click the service. And same message on every service.
Now I tried anotehr way. I call the ess startpage directly on the external java stack. And here´s no problem. All WebDynpro-Services works fine.
Can anyone help me, why the WebDynpro Service doesn´t work in the Portal?
Best regards
Christian

We had exactly the same problem. We had multiple java servers and our switch was not retaining stickiness. So it would send the user to a different java server which hadn't got any session data for that user.
If this could be it, get something like httplook to do a trace of what is happening. We saw it switching java servers.
If you do not have multiple servers it could be switches chopping out cookies, causing the same issue.

The Web Dynpro application 'UWL' has expired

Hi ALL,
We are using Enterprise portal 7.0. and backend SRM server
When the user login into portal it will take him to the UWL page
in that the user click for any "Approve shopping cart" the error message showing
" The web dynpro application *'UWL' has expired. restart the application. choose 'refresh' in the iview tray or use the*
*browser 'refresh' button to restart the iview"*
user not getting the error message every time. error coming occasionally
we suggest the user to clear the cookies and restart the browser and relogin.
but some times it works some times not
Can any one know the exact problem (any parameters has to be change or any other solution)?
Regards,

SAP NW.BASIS Consultant

Dear Abdul ,
Hope you are doing good.
We have seen similar cases of WD Session Expired error message when the jsessionid cookie issued by the server with the initial requests was not returned from the client with subsequent requets to the server. The only way to ascertain whether this is the case in your system will be by checking the HTTP watch trace (note 1558903 - How To Trace a Portal Scenario Using HttpWatch).
As the jsessionid cookie is used for session management, when it is missing from the request headers the correct session could not be retrieved and as result new session will be created for that user. Set the parameter JSESSIONID.CookieDomain to "NONE" as mentioned in the sap note: 791765 and see if the issue persists. This configuration should be accessible in
Config Tool -> expand the tree "cluster-data" -> "Global Server Configuration" -> "services" -> "servlet_jsp" -> Go to "Global
Properties". Do make the changes, save the customization and then restart the complete SAP server (not just the JAVA server nodes).
Kindly go through the note completely.
Also make sure that the SystemCookiesDataProtection and SystemCookieHTTPProtection is set in the HTTP Provider Service on
the server nodes.
Do make the changes,save the customization and then restart the complete SAP server.
Thank you and have a nice day :).

Error message display in web dynpro application?

Hi All,
In my web dynpro application I am displaying error messages but the focus does not go to the field where error occured and also if I click on the error message it does not lead to the place of error.
And also when I navigate to another view the error message does not go.
Below is my code:
*    report message
      DATA err1_text TYPE syst-msgv1.
      err1_text = wd_assist->if_wd_component_assistance~get_text( key = '002' ).

        EXPORTING
          msgid      = 'ZAA'
          msgno      = '005'
          msgty      = 'E'
          p1         = err1_text
        RECEIVING
          message_id = lo_text.
Please suggest me the way to do it.
Thanks & Regards

Hi,
I got your point.. in the BIND_TABLE( set_intiail_elemts = abap_true) change this to ABAP_FALSE.
Because of this you are gettng the intiial values. Eventhough your table has no BALNK/space records.
bind a single element
node->bind_table(
    new_items             = lt_year_list
    set_initial_elements = abap_true ).
change as
bind a single element
node->bind_table(
    new_items             = lt_year_list
    set_initial_elements = abap_false ).
You can use this code - I have tjhe dropdwon for projects event I'm doing the same.
navigate from <CONTEXT> to <PROJECT> via lead selection
lo_nd_project = wd_context->get_child_node( 'PROJECT' ).
***Gets the selected project id from drop down
if lo_nd_project is not initial.
    CALL METHOD lo_nd_project->GET_LEAD_SELECTION
      RECEIVING
        ELEMENT = lo_el_project.
get all declared attributes
    if lo_el_project is not initial.
      lo_el_project->get_static_attributes(
        IMPORTING
          static_attributes = ls_project ).
change your code to
lo_nd_year_list = wd_context->get_child_node( name = wd_this->wdctx_year_list ).
***Gets the selected project id from drop down
if lo_nd_year_list is not initial.
    CALL METHOD lo_nd_year_list->GET_LEAD_SELECTION
      RECEIVING
        ELEMENT = lo_el_year_list .
IF lo_el_year_list IS NOT INITIAL.
    get single attribute
    lo_el_year_list->get_attribute(
      EXPORTING
        name = `YEAR`
      IMPORTING
        value = lv_year ).
