Problems using ALSM_EXCEL_TO_INTERNAL_TABLE in Web Dynpro ABAP

Hello experts, im using the fm ALSM_EXCEL_TO_INTERNAL_TABLE.
When i call this fm from a web dynpro i have a dump that says that cannot import the clipboard.
Any ideas why this is happening?
(The parameter of the function are Ok, becouse if I call the function from SAP/R3 everything work fine)
ThankS!

I didn't mean to imply that there is a Function Module that should work from Web Dynpro. In fact I would be highly suprised if there was one. As already posted in this forum, the only way to get data from the client desktop is with the fileUpload UI element. No function module is going to be able to work with the Web Dynpro UI element.

Shooping cart creation in SRM 7.0 using web dynpro ABAP classes.

Hi,
We have recently upgraded to SRM 7.0 from SRM 4.0. We are using customized portal application for the creation of the shopping cart.I am planning to create custom FM which will use the standard Web dynpro ABAP classes to create the shopping cart.
Could you please guide with the classes that are need to be implemented and the sequence of the classes used in the shopping cart creation.
I think these are the classes that are used in the standard web dynpro ABAP component.
CL_FPM_EVENT ->                  Creates an instance of this class based on an event ID.
CL_BADI_FLT_DATA_TRANS_AND_DB -> Data Handling: Transport and Database.
CL_EXITHANDLER ->               Class for Ext. Services Within Framework of Exit Technique.
CL_EX_BBP_DOC_CHANGE_BADI ->     BAdI Class CL_EX_BBP_DOC_CHANGE_BADI.
CL_BBP_OBJECTS_ACCESS ->         Access Functions for Object Types.
/SAPSRM/CL_PDO_BO_SC ->          Shopping Cart BO.
Your expert comments will be appreciated...

Ajax/Javascript in Web dynpro ABAP

Hi,
I need your help in figuring out what artefacts of web dynpro ABAP could help me resolve a problem.
In a Web dynpro abap application, we have a button that redirects a user to an external site. Some of our users can go to this site from their computer and some others can't because they are not allowed. I would like to be able to show the button only to the users that have the right to execute this navigation.
In order to do that, I need to embed some script in my web dynpro application that will test if the URL of this application sends back an HTTP/200.
With the latest versions of Web Dynpro ABAP, is it possible to embed javascript of ajax? How can it be done?
If not, what could I use to base the visibility of my button on a validation that has to run on the users's browser?
Thank you very much for your help!
Renaud

Another way it could be done creating a custom ztransaction (abap report) performing a PING to the ip server , reading log txt, saving if the user is authorized or not , and redirecting to the Abap Web Dynpro.
Then On wddoinit select zztable for authorization.
But i don't know if this solution will work for you (ping specific port 80? or other requirements)

Problem in web dynpro ABAP program

There are 2 input fields on first view carrid, connid and one "GO" Button
1) "FLIGHTINFO" is the node under context of first view
2) " FLIGHTTAB " is a node under context of component controller having cardinality " 0..n " ,Dictionary structure "SFLIGHT" (i have selected only these many attributes " carrid, connid, fldate, planetype, seatsmax and seatsocc " )
3) I have created Method "FLIGHTTAB_FILL" in component controller to fill context node FLIGHTTAB
Insert the source code for doing the following:
-     Navigate to context node FLIGHTINFO
-     Get element at lead selection for context node FLIGHTINFO
-     Get CARRID and CONNID
-     Fill an internal table with all datasets from database table SFLIGHT, who meet the constraints for CARRID and CONNID.
-     Navigate to context node FLIGHTTAB
-     Bind the internal table(having all standard fields of sflight ) to the context node FLIGHTTAB ( having those 6 attributs).
4) On action GO ->Implement the invocation of Method " FLIGHTTAB_FILL".
5) I have mapped node FLIGHTTAB to context of OUTPUTVIEW. Display table on view OUTPUT_VIEW (for this i hav used code wizard).
Problem: after entering values of connid & carrid I m getting proper entries in internal table. but output view is not at all trigger (although i have created plugs). Is it necessary that while binding internal table with context node FLIGHTTAB should have same no of fields (i.e. in this case 6 )?
I am a fresher, My concept of bindings and cardinality are not so clear so can anybody help me out?
Thanx in advance for replying.

Hi johnright ,
    No i dont think it is necessary that while binding internal table with context node should have same no of fields as the internal table . You might get some improper values in the corresponding fiels but it will not lead to any error.
In your OUTPUTVIEW once you created the table UI element in layout and you bind it to FLIGHTTAB node you dont have to use any code wizard method to display the values. If the node contains values it will display automatically. (in your case you are filling it in step #).
Check :-
1. In your On action GO after filling the table you are firing the out bound plug :-
    WD_THIS->FIRE_INITIAL_OUT_PLG(
2.All outbound plug and inbound plug are link properly and every thing is ACTIVATED.
If still unable to find the error try to debug method wise and find where the error occurs and reply to us.
Binding:-
In web dynpro ABAP you will not able to get any value of any variable outside of any method. Here we use context node which is referrence that we create reference to any particular structure we required. Now to hold the values you need to bind
the values of your internal table to the context node.
If the node is in view then its values are visible to all the local method of the view.
If the node is in component controller then the you bind a value to the node from one view and you can get it in another view.
Remember binding and mapping are not same.
Mapping is done between node like inthe second scenario i have explained you need to create a node in view controller and then you need to map it to the corresponding view of component controller to send values across view.
cardinality:-
Each node contains data fields that represent one of the following:
    An individual instance of an object type
    A table of instances.
This property of a node is known as its cardinality of table of instances.
If you need table instance :- 0..n or 1...n
   In case of 1...n one default value is created. generally we use this as mainly we need to work with table.
In case you need a individual instance of a object or like you want value like a structure only :- 0...1 or 1....1.

Problem with Table display in Adobe Form of Web Dynpro ABAP

Hi Team,
I'm trying to display a table in Adobe Print Form (not interactive). The table is bound to the context node in the Web Dynpro ABAP where the cardinality is 0:N. I get a short dump. Don't know what to do here. I'm able to display individual fields from my context successfully. Looks like something is missing when I try to display a table. Any pointers to display a data table in Adobe? Any step by step example you know of where I can find out what I did wrong? Many thanks for your time
We are on support pack SP06 on 2004S release.
DUMP INFORMATION:
Short text
    Access via 'NULL' object reference not possible.
What happened?
    Error in the ABAP Application Program The current ABAP program "CL_WD_ADOBE_SERVICES==========CP" had to be terminated because it has come across a statement that unfortunately cannot be executed.
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 procedure "CREATE_PDF" "(METHOD)", nor was it propagated by a RAISING clause.

Hi Thomas,
We upgraded our system(2004S) to SP10 so that we can use the ADOBE form printing in Web Dynpro ABAP but could not apply note 1034425 because of the validity constraints in SNOTE. All the pre-requisite notes are already in the system apart from one note 1029721 which talks about supporting input helps. We don't want to use input helps in our system and cannot upgrade to SP11 because of problems with Business functionality.
Questions:
1) Is note 1034425 absolutely dependent on 1029721?
2) If NOT, can someone please correct the validity so that we can implement using SNOTE.
3) Would it be OK if we manually apply the changes specified in 1034425 without implementing 1029721?
4) If all of the above is not applicable, is there any other note which fixes the above mentioned short dump.
Your help in this matter will greatly help us in using the ADOBE services provided by SAP WDA.
Thanks much

Problem with image loading in flex (with web dynpro ABAP integration)

Hi,
I am working with integration of flex and web dynpro abap. I am facing unusal problem while loading the images. I have the images in the MIME folder of web dynpro application. Since my swf file and all the images that I want to use are in the same folder(MIME), I am accessing them giving just the image name as source for the image in flex.
By this method I get the images sometimes, but not everytime. So could anyone suggest me alternative method.
Regards
Prashant Chauhan
Edited by: Prashant8809 on Jul 17, 2011 11:56 AM

Hello Prashant,
you need to mention the full path as source for the image in flex.
ex. if your WD application name is Z_TEMP and image file name in mime folder is 'image.jpg' then you need mention the source in flex as
http://servername:50001/sap/bc/webdynpro/sap/Z_TEMP/image.jpg
Hope this solves your problem.

Sequencing Problem in Web Dynpro ABAP

Hi Web Dynpro (ABAP) Guru's,
Can anyone tell me how to read a parameter from the WDA url in my view? The situation is like this: My WDA is being rendered in the Portal EP 6.0 as an iView. When my WDA is called the portal also appends in the URL the plant number. I want to grab that plant number and use it in my view to show some default data.
As per other weblogs/forum posts I defined a parameter "PLANT_NO" in the "Default" startup plug of my Main window. I'm using the Get_Data method to read this parameter in the plug. I'm able to read the URL parameter here and so far it is good. Read below for the problem..
If I understand the order of operations correctly, doesn't the views get created, then the default plug code is run, then the views are placed on the window and then shown to the user. Since my views are created before my default plug is run I DO NOT get the URL parameter value in the WDDOINIT of my view. When I debug the application, the WDDOINIT of the embedded view gets called before the Default startup plug. Am I missing something here?
If someone can tell how to read the URL parameter in the WDDOINIT (instead of Default Startup) of the view I could default in the data I want to display. OR any other suggestions to get past this problem would be appreciated.
Does this make any sense and does anybody have an idea of where I could find some info about how to do this?
Thanks much for your help. Points will be awarded.

Thanks Klaus for the response.
I don't want to read the parameter from the default plug, but need to access the URL parameter and display default data in my view. Let me explain the scenario:
My Web dynpro application is called from the Portal. The Plant number is passed in the URL as:
http://...../sap/bc/../../<Web Dynpro Application name>?PLANT_NO=0012
I want to show Material Stock values in the view for Plant "0012". To access this value I've defined a parameter with same name (PLANT_NO) in the default startup plug of my main window. I get access to the URL parameter through this plug parameter.
I have only ONE view embedded in this window where the Stock values are selected from table MARD for the specified plant. I want to get the plant value from URL in my WDDOINIT method to make this selection from database. I'm then binding the results to the view table UI element. My problem is that the URL parameter is read in the Default plug, but the data selection and view binding happens before in the WDDOINIT method where I don't know the plant.
Again, I don't want to read the plug parameter, but I want to get the URL parameter (PLANT_NO) and then render the view based on the data selected for this parameter. Please let me know how this can be achieved by reading the URL parameter in WDDOINIT method (Constructor) so that it can be used subsequently in the application.
Thanks for your help and looking for a resolution.....

Is Web Dynpro ABAP being used in production?

Friend,
My company wants to start using Web Dynpro ABAP.
I wanted to know if Web Dynpro ABAP is in ramp up mode or the latest release is good for production?
Are many of you already using Web Dynpro ABAP in production?
Thanks in advance.

THere are many ramp-up customers that are currectly developing/using WDA. It is still in ramp-up and not available for general customers. Are you a ramp-up customer for Netweaver 2004s? If so, you are free to develop and use WDA. If SAP felt that it wasn't ready, they probably wouldn't have released it for ramp-up. Any problems that have come out of ramp-up, have probably been addressed and fixed with support packs.

Shared memory used in Web Dynpro ABAP

Hi Gurus,
I am using shared memory objects in Web Dynpro ABAP. Everything was working fine until we went live to production. After some research I realized that users are not always able to reach data in shared memory because of different approach of web environment and classic GUI when using more servers. Solution would be to go to database instead of shared memory. However I am still interested if there might be some other way to solve it. Any ideas?

To my understanding writing to the database is the safe option. There are no other ways to solve your problem with Shared memory.

Problems creating new Web Dynpro ABAP application

All,
I am following this tutorial to create my first Web Dynpro ABAP application
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/fc/501b42b5815133e10000000a155106/frameset.htm
In this tutorial I was asked to create a component as Local object.
But after giving the name of the component, I get an alert saying
"Object can only be created in SAP Package"
When I confirm this, I was shown a "Create Object Directory entry" dialog box which asks for attributes like Package.
And this box has Local Object button, when clicked I get the message "Test Objects cannot be created in foreign namespaces".
I found some other article through Google
http://www.octavia.de/fileadmin/octavia_files/content_bilder/Hauptnavigation/SAP_NetWeaver/WebDynpro/Web_Dynpro_Part_I.pdf
According to this, I tried to give $TMP as Package. But still have the same error
"Test Objects cannot be created in foreign namespaces"
Where am I and what should I do to create a new project?
Thanks.

Thanks Abinav.
My problem is with naming convention only. Component name starting with Z solved my problem.

Adobe form to save data using Web Dynpro ABAP

Hi. I am pretty new to SAP world and trying to learn and work on a task given to me relate to
creating Adobe offline form using Web Dynpro ABAP same time.
I have several questions and hopefully, many gurus like you will provide answers.
I noticed there are many examples creating and using Adobe interactive forms (though not many newer version),
but I didn't see (at least I didn't find any) any detail example on saving data to an internal table (such as fixed assets, vendor master, etc)
using interactive form. Is there any detail explanation/example on this?
I have ask this question in another forum (before I found this forum) but didnu2019t get the answer yet.
2. When I tried to see graphic layout and modify the layout from Web Dynpro, I can't see the graphic layout.
All I see is text list of fields/buttons that I created, but can't see section for graphic layout where I can modify layout.
I am sure I didn't install/configure something correctly.
Anyone has any idea what I didn't do?
I have another question, but I will wait till later after I figure out above ones first.
Thanks for all your help in advance.
John

Hi John,
In the WD4A view, there is a button "Show/Hide Layout Preview".
Click on that button to be able to see the Layout.
Note that this button is next to the Pretty Print button.

Reading HTML Content using Web Dynpro ABAP

Hello,
I was wondering if it is possible to read the content (HTML) behind a given URL using Web Dynpro ABAP. If so, are there any functions available to parse the HTML ? I have been asked to develop an application that requires going to a URL, reading the content, and formatting a table from that content for presentaion within Web Dynpro ABAP. The HTML of the URL is nothing more than a "Table of Contents" to existing documentation ( Word Documents )
Thank you for any help / advice you can provide
Larry

You can get the HTML returned in a table using fm RSFO_HTML_REQUEST2.
Once you have that, you can convert it to a string using any number of methods. CL_RSR_WWW_RENDERER=>TABLE_TO_STRING should work fine.
One option for parsing it would be to get it converted into an iXML object, but you might have to do quite a bit of manipulation first depending on what the html looks like. You can see more info here on iXML classes: [http://help.sap.com/saphelp_nw04/helpdata/de/86/8280ba12d511d5991b00508b6b8b11/frameset.htm|http://help.sap.com/saphelp_nw04/helpdata/de/86/8280ba12d511d5991b00508b6b8b11/frameset.htm]
Otherwise I would just make use of find statements with regex patterns to sort through the html.

Rules Engine using Web Dynpro ABAP

Hi,
Can we build a Rules Engine which works with Web Dynpro-ABAP? Something similar to BRM in CE-7.2.
Thanks,
Prasanna

Do you mean BRM or BRF. BRF is the name of the business rules framework that is integrated in the ABAP engine. BRM is Business Rules Management and a part of NetWeaver CE - running on the Java Stack and a part of SAP NetWeaver BPM (Business Process Management).
Generally if your work is all ABAP based you would use BRF. Here is a small eLearning that shows the usage of BRF within Web Dynpro ABAP.
