Extend ABAP Webdynpro session

Hi experts,
Is there a way to extend the abap webdynpro user session?
The problem is that the users want to have 30-40 minutes gap between any user interaction on the application (e.g. they are on a meetting they discuss something, then enter a value to the webdynpro application then they are discussing another issue, and after 30-40 min they enter another value to the WDA application)
Currently the application cannot have 30-40 mins gaps between two user interaction, becase the whole app will end in a session timeot error.
Thanks
N.

Yes there is. Check the following help link:
http://help.sap.com/saphelp_nw04/helpdata/en/25/7e153a1a5b4c2de10000000a114084/content.htm
Roughly speaking it's the parameter rdisp/plugin_auto_logout within ICM. This will allow you to extend the timeout counter.
My advice: Do not extend it. Since people are both demanding AND stupid, this will not only lower your security and your performance but people will quickly ask you to extend it, AGAIN, so they can have an hour lunch break period between WebDynpro interactions...
Hope it helps you though
regards, Lukas

ABAP WebDynpro - Session remains open....

Hi Experts,
We have configured ABAP Webdynpro (SD Order Creation) iView in SAP Portal. When we test it from intranet, everything works fine and session in backend gets terminated when we leave that page on portal. But when we test it from internet, session remains open and not getting closed. How to terminate these onen sessions??
SAP Portal and backend SAP ECC are on same domain....
Helpful answer will be respected.....
Thanks

Hi Parmod,
are you accessing the application in exactly the same way in the two cases?
logging into portal from internet?
One thing that you might need to be wary of is a lack of pop-ups. The portal uses a pop-up window when a user closes the browser to terminate the session.
I've had plenty of problems with pop-up blockers that have prevented this pop-up from terminating the portal sessions. Sometime these pop-up blockers are configured to operate only on internet sites and not on internal intranet sites. That might be a possible cause.
Cheers,
Chris

WebDynpro ABAP - inter session events possible?

Hi Experts,
I have a ABAP-WebDynpro application with various tabstrips to show and maintain process data within a production process. Each tabstrip contains several data of a specific process step. At the beginning, very few data are already present. While production progresses, chemical analysis is being taken and machine data is gathered. Assoon as new data for the process step is available, a refresh should be performed.
Though not perfect in every aspect, we made this scenario work in a similar way in ABAP Dynpro by using inter session eventing (ISE). Is there a possibility to trigger events in WebDynpro cross-session - for example after adding data to the database?
Best regards
Jens

There is no real cross session eventing available in Web Dynpro. The problem is two fold. First, UI updates can't be initiated by the server in HTTP (unlike the SAPGUI which does have a push mechanism to the client). This is a current limitaiton of HTTP itself and not something Web Dynpro related. So to trigger the phase model of Web Dynpro, something must occur on the client to trigger the server event. In NetWeaver 7.0 and 7.01 you have to use the timedTrigger UI element to acomplish this:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/da/a6884121a41c09e10000000a155106/frameset.htm
You then generally used a shared memory object (or even temporary database entries) to communicate data or events between to different processes. For instance a background job is running and places it status in a shared memory object attribute. The Web Dynpro can then fire a TimedTrigger every minute to check the value of this shared memory object attribute.
In NetWeaver 7.02 we improve this process with a new capability called the Web Dynpro Notification Service. Instead of the timedTrigger, we can simulate a push of data/events to the client using AJAX. We open an secondary server request to the ICM to check the status of an event. That way we don't have to disrupt the client side activity or incurre the full Web Dynpro Phase Model until we know a change in the status of our event has occured. Also since the status info is stored in the ICM Cache, you don't even have to fall into an ABAP Workprocess to check the status.

Calling a PP03 BDC from abap webdynpro throws an exception from the class

Hi Experts,
I am calling a BDC FM for PP03 TCPDE form abap webdynpro.
When i run the standalone FM, it works fine and When called from Webdynpro its giving a dump saying an exception is raised in the class CL_GUI_SPLITTER_CONTAINER.
Can you please let me know how to resolve the issue? Your siggestions will be of great help to me.
Thanks,

Hi,
The FM might be calling a dialog or bringing a GUI screen up. This would cause the Webdynpro session to disconnect abruptly.
Any conversion exit, GUI screen,dialog popup, transaction handling..etc would cause the webdynpro to disconnect. So you cannot use all FM's as it is.

Is it possible to launch a Screen Personas screen from an ABAP WebDynpro application?

I am running SAP EHSM Incident Management within SAP Portal. EHSM has an ABAP WebDynpro frontend based on BOPF/FPM
In the same portal session for a single user, we want to be able be in an
active record in EHSM and then launch a screen personas screen based on a
SAPGUI transaction from either a button click or portal tab click. As part of
the launch, we want to pass an HR PERNR ID to the Screen Personas/SAPGUI
transaction from the active record in EHSM and run a search. Is it possible to
do this? Project team is saying this is a technical limitation.
I know that Screen Personas cannot be used for a WebDynpro screen, but we just want to launch a screen and pass a parameter. We assumed during blueprint this would be possible.
Thanks

This is definitely possible.
Here is a link containing an example of building the URL to start a transaction via Personas and pass a variable plus a command in the URL. This could be enhanced with specifying the flavor as well.

Debugging abap webdynpro application

hi gurus,
an abap webdynpro application is runninf fine in developmernt server but not in production system. i transported the application again to refresh the application in production. but still the error persists. now i want to debug the abap editor in production system. so i wrote code 'BREAK POINT' in abap editor. but program is not stopping at this code. in dev as well as in prod system. please suggest.
Moderator Message: There is a separate forum for Webdypro for ABAP. Please post your question there.

Hi
Few links to check:
External debugging is not working
Re: Debugging Abap webdynpro appln
Re: Unable to Debug WD ABAP application
Dedug is not working in Production Server.
a) Check on number of R/3 sessions opened at a time.
b) Check that user ID configured in portal using System Mapping Under 'Delegate User Administration' is the same user for which you are setting external breakpoint in backend system.

Internationalization in ABAP Webdynpro

Hi All,
What is the methodology for implementing ABAP webdynpro. Can any body let me know what are the various possiblities for Internationlization.
Regards
Vijay

Hello,
To implement Web Dynpro ABAP you must use the MVC (model, view, controller) model, and about internationalization you can use the [OTR (online text repository)|http://help.sap.com/saphelp_nw04/helpdata/en/36/00f13a62d1ad6de10000000a11405a/frameset.htm].

Your opinion on: BSP or Java Webdynpro or ABAP Webdynpro?

Could you please give me your opinion on the business scenario we have here:
We are implementing SRM 4.0 with backend R/3 4.6C, WAS 6.4 and Portal 6.0. SRM has its typical shopping cart applications mainly for procurement and the workflow trail displaying the approval. The client wants us to build a few custom forms on the web frontend of SRM (or may be in Portal). The idea is to store these forms and display when needed with the status info just like a shopping cart.
Now the requirements for these forms are as follows:
1. These forms will have multiple fields which need to have the F4 kind of help. (the F4 options will reside in SRM or R/3)
2. The form should have some kind of a ALV grid (autoexpanding feature) which will allow the user to put in multiple line items so that they could submit more items on one form.
3. Users need to be able to attach a spreadsheet to the form which should not be editable once the form is submitted. The attached spreadsheet should be stored. (We are planning on using Archivelink Filenet for this)
4. Upon submission, a workflow will be kicked off as per the defined Org structure for approval of the form.
5. After submission, the user should be able to go and view the approval status of the form and also print the summary of the values that he entered in the form. (may be a smartform could be provided for this)
We looked at different options to accomplish this task:
BSP:
Creating BSP pages and giving access as links to the user on the webfrontend of SRM. Now, if we go the BSP route, we need to develop in SRM as the R/3 4.6 c does not have BSP development capabilities. If we take this approach, I am not sure if all the above requirements (specially like attaching spreadhseets) will be met with BSP pages.
SAP Webdynpro Java:
It seems that the Webdynpro is easier to use because of the graphical tools available. But the only problem if we go this route is that we will have to find a java guy.
SAP Webdynpro ABAP:
We currently have WAS 6.4. As per the documentation, the ABAP Webdynpro development tool is available from NW04s onwards. So, we are still not sure if we could use it. But, we want to push towards upgrading if necessary. Being an old time ABAPer, developing ABAP Webdynpro seems do-able. (i know it may not be that easy).
Last but not the least, DIALOG Program:
Creating a dialog program in R/3 or SRM seems fairly simple. Then, an iview could be created on the portal for this transaction, though at this point I am not sure how a spreadsheet could be attached and stored within a dialog program.
The creation of the workflow may not be that bad after the original form is designed. The graphical display of the approval trail might be difficult, but we might get away with a report for that. For printing the details of the form, I guess I could develop a smartform and put out a button on the screen to print it out in the display view.
Could you please give me your opinion / best approach for accomplishing this task, keeping in mind the complexities of these new dimension products?
Thanks
Sri

I would say that all four solutions to solving your tasks are technically feasible. Here are some thoughts that I had however:
First ABAP Webdynpro: it is true that ABAP webdynpro is only available with Netweaver04s. 04S is still in ramp-up which means that only a subset of the customer base is allow to implement it. It will not become generally available until later this year (check the service marketplace for current release estimates). That being said, it probably elimintes WDA as a possiblity for your project unless you are will to wait and to upgrade.
However having worked with WDA for a while it is probably the best tool to custom develop what you describe. It has excellent built-in F4 value help. It also has a damn fine ALV grid implementation. The spreadsheet could be just as simple as file upload in binary or your could try your hand at office integration. Finally for the form you could use Adobe Interactive Forms which also has very nice integration into WDA.
Now to Dialog Programming: You could of course use dialog programming. It seems a little bit of a waste to custom build something so large if WDA is in your near future. There are obvious disadvantages (little OO structure, no MVC, etc). You would have ALV grid, office integration and of course F4 help. You could still use Adobe forms if you implement this on the 640 system. However there are integration points with dialog and Adobe Interactive Forms. You could still use printed forms however. If you did the dialog program on the 640 system, you could use the integrated ITS to expose it to the web. The integrated ITS in my experience has quite nice performance although the look and feel remains just like the SAPGui.
The Java Webdynpro route: Well you hit the nail on the head - if you don't have a Java programmer already and you don't have the bandwidth to invest in learning Java, this can be a problem. The Java Webdynpro environment is quite nice. There are some things I like better than ABAP and some things that ABAP is defintely still better at. However when it comes to heavy integration with an ABAP backend - ABAP Webdynpro is still the way to go. Java Webdynpro does have a help feature (OVS), but it isn't "for free" or nearly as nice as the ABAP Webdynpro (perhaps it will get there some day). That is one of the major advantages of WDA - its closeness to the business data brings several framework advantages like F4 and field help. WebDynpro Java in 640 also doesn't have an ALV grid implementation. I am sure that this is something both environments will eventually have, but right now ABAP has the advantage. On the other hand, Webdynpro Java has equal support when it comes to office integration, file upload, and Adobe Forms support. You would have a more difficult time integration SmartForms however.
Finally we come to BSP. Honestly if I were in your position I would probably choose BSP (unless you could wait for the ABAP Webdynpro upgrade). You could build a nice MVC OO application using BSP (stateful or stateless). The BSP product is mature and quite well documented thanks to SDN. You have the BSP Extensions which when used in Design2003 use the Unified Renderer. That means that your output will look nearly identical to the same UI elements in Webdynpro. Also BSP supports portal integration (session management, eventing, and themes).
The downside to BSP is that it isn't a full framework (also one of its advantages). You can insert all your own html and javascript (unlike webdynpro). But this also means that SAP doesn't delivery as many framework services. For instance there is no ALV or Value Help. There is no Office Integration or Adobe Forms integration. There is some farily good Smart Forms integration. Now the upside- many people have already hit these limitations and overcame them. In the weblogs on SDN and in a certain SAP Press book (cough, cough) you will find out of the box solutions for many of these problems. You can find ready to use solutions for Adobe Integration, Office Integration (using Microsoft Office Web Controls), and F4 help. It will mean investing a little more time up front to get this "home grown framework" up and running - but it is perfectly feasible.
There is a learning curve to all these new technologies however. This sounds like an abmious project. I wouldn't want to try and tackle this project in any of these technologies if I was new to them. With Webdynpro or BSP - consider giving yourself time to learn the environment and cut your teeth on some demo apps before jumping into such a huge development.

SOFM: Dsiplay method is not working when called from ABAP Webdynpro

Hi All,
I want to open an attachment from ABAP Webdynpro.
I have approached in this fashion:
1) Get the attachments as SOFM object key
2) On Click of a link on Webdynpro, I am calling a function module within which I am creating an instance of the SOFM object
3) Then I am calling the DISPLAY method
It is not opening.
But, if it opens when I driectly execute the function module. It open when I directly test the business object.
Any Idea ?
Thanks & Regards,
Deb

Display Method uses the Dialogue Module, You should not access such methods in web dynpro which are SAPGUI specific.
Web Dynpro Applications are run in Browser environment which cannot understand Dialog, it can understand only HTML.
Read the attachments and get the content and use FileDownload UI element to show it to user.

Hi,
As far as i know when you use Adobe forms in a WD4A application, language is your "web" connection language.
You can have a look at standard class CL_WD_ADOBE_SERVICE, it's used when generating an adobe forms from WD4A. , more particulary look at method DETERMINE_DOCPARAMS.

Doubts in ABAP WebDynpro

Hi Experts,
I am new to ABAP WebDynpro and self-learning going through SDN stuff and other online-help. Please provide me
your kind explanation on below doubts.
1. When do we use GET_ATTRIBUTE and GET_STATIC_ATTRIBUTE
2. How to read the index of a particular selected row in table?
3. How do you change position of a particulr node dynamically?
4. Is it possible to execute a component without a window?
5. Is it possible to run a VIEW without embeding into a window in Webdynpro application?
6. How to read the content entered in PARAMTER and SELECT-OPTION elements in ABAP Webdynpro? Can anybody pass code how to read entries?
I mean GET_ATTRIBUTE or GET_STATIC_ATTRIBUTES is used for reading attribute value.
7. Is it possible to fix the Message window position? Show at the bottom of a screen? Please provide some code for this.
8. Is it possible to change the color of a laber attached to a attribute dynamically? For example somefield is mandatory but you forgot to enter and press on u2018Continueu2019 then program should show that elementu2019s lable with redcolor text. Please provide me example code.
Thanks in advance for the support and useful explanation!
Regards,
Meera.

Hi
Refer the answers inline
1) When do we use GET_ATTRIBUTE and GET_STATIC_ATTRIBUTE
GET_ATTRIBUTE
Method to get the values of a context attribute.
The prerequisite for this method is that the application knows the data type of the attribute.
The value of the given attribute is copied to the export parameter. To do this the export parameter must have a data type to which a value can be written.
GET_STATIC_ATTRIBUTES
This method copies the static attributes to the transferred variable. If the structure is not identical, a move-correspondingis performed, which is not as efficient as a direct move, but is still useful in many cases.
Static attributes are those that either have been declared or that belong to the structure with which the node was declared.
2) How to read the index of a particular selected row in table?
data: lr_element type ref to if_wd_context_element,
 lv_index type i.
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
lv_index = lr_element->get_index( ).
3) How do you change position of a particulr node dynamically?
 Explain Bit deeply
4) Is it possible to execute a component without a window?
 No it is not possible, actually the component view can be viewed by embedding it to the window
5) Is it possible to run a VIEW without embeding into a window in Webdynpro application?
 No it is not possible, without window you cant run the view
6) Is it possible to run a VIEW without embeding into a window in Webdynpro application?
DATA LO_ND_MAIN_NODE TYPE REF TO IF_WD_CONTEXT_NODE.
DATA LO_EL_MAIN_NODE TYPE REF TO IF_WD_CONTEXT_ELEMENT.
DATA LS_MAIN_NODE TYPE WD_THIS->ELEMENT_MAIN_NODE.
DATA LV_INP_VALUE LIKE LS_MAIN_NODE-INP_VALUE.
navigate from <CONTEXT> to <MAIN_NODE> via lead selection
LO_ND_MAIN_NODE = WD_CONTEXT->GET_CHILD_NODE( NAME = 'MAIN_NODE' ).
get element via lead selection
LO_EL_MAIN_NODE = LO_ND_MAIN_NODE->GET_ELEMENT( ).
get single attribute
LO_EL_MAIN_NODE->GET_ATTRIBUTE(
 EXPORTING
 NAME = `INPUT_VALUE`
 IMPORTING
 VALUE = LV_INP_VALUE ).
7) Is it possible to fix the Message window position? Show at the bottom of a screen?
 Yes it is possible to show the messages by using the message area UI element in the needed position
8. Is it possible to change the color of a laber attached to a attribute dynamically? For example somefield is mandatory but you forgot to enter and press on u2018Continueu2019 then program should show that elementu2019s lable with redcolor text.
 Im working onit and let you know after i complete.
