Add/Delete elements from viewcontaineruielement in web dynpro abap

Dear all,
Please let me know how to Add/Delete elements from viewcontaineruielement in web dynpro abap? I have copied a viewcontaineruielement from another program and now i dont want few elements from that viewcontaineruielement in my view. Please guide

Hi Ajinkya,
I have copied a viewcontaineruielement from another program and now i dont want few elements from that viewcontaineruielement in my view. Please guide
Have you saved that VC element as template and using that template in another component?.If so,on resuing that VC element template it populates all the screen elements which you've save as template.
Now, select that VC element which you've re-used,based on you're requirement add/remove UI elements as Kiran suggested.
Hope it will resolve your issue.

How to add screen elements at run time on button click in Web Dynpro abap?

Hello All,
I have a requirement wherein the user wants to add the textbox dynamically at runtime on button click action. My questions is, Is it feasible to dynamically add screen elements at runtime? If yes, how?
Please help.
Thanks

Hi Ajinkya,
This is absolutely possible! Adding view elements at runtime is called "dynamic programming". There are a lot of good resources and tutorials on SCN if you do a search. To start you off, here is an excellent series by Thomas Szücs:
Dynamic Programming in Web Dynpro ABAP - Introduction and Part I: Understanding UI Elements
Dynamic Programming in Web Dynpro ABAP - Part II: Handling ViewElements
Dynamic Programming in Web Dynpro ABAP - Part III: Aggregations and DDIC-Binding of ViewElements
Another option that avoids dynamic programming is to create the view element at design time but bind its visible property to a context attribute of type WDUI_VISIBILITY. You could initially set its visibility to "none" until the user clicks the button, then you could change its visibility to "visible".
Cheers,
Amy

How to add button ui element in alv table data in web Dynpro ABAP

Hi Experts,
I have one requirement,
Actually I was devloped normal table in web Dynpro ABAP
in that i have one column Display as a button .
when i select that button need to display some data.
same requirement i need to devlope in alv table.
i am going to attach file please check.
Thanks in advance.
Regards,
Subba Reddy.

Hi,
You can create Button in your ALV table column with below code
DATA lo_button              TYPE REF TO cl_salv_wd_uie_button.
CREATE OBJECT lo_button.
    CALL METHOD lv_value->if_salv_wd_column_settings~get_column
      EXPORTING
        id    = <your column name>
      RECEIVING
        value = lo_system_select_hdr.
    lo_button->set_enabled( value = abap_true ).
   lo_button->set_text( value = 'Avaliable List' ).
    lo_button->set_tooltip( value = 'Avaliable List' ).
    lo_system_select_hdr->set_cell_editor( value = lo_button ).
And for button click action,
Create a method (say SHOW_DATA( ) ) with on_click event handler.And when you click button on your ALV table, SHOW_DATA( ) method will trigger.
Thanks

Integrating Flex/Flash in Web Dynpro ABAP(Netweaver 7.0) need info!

Hi all,
I need to embed a flash or a flex object inside a web dynpro abap application.I am working in Netweaver 7.0 and i don't have enhancement pack 1 installed.Is it possible ? If it is possible can anyone please provide me the coding and configuration details.
Thanks,
Saikat

I'm afraid that the SAP supplied integration technology - call FlashIslands - is only available from NetWeaver 7.01 and forward. You could perhaps do some simple integration (very little data transfer) with the iFrame UI element - although the iFrame is deprecated in 7.0 and 7.01, but does return to full support in 7.02. The other option would be to use the NetWeaver Portal or NetWeaver Business Client and have two iViews within the page. One iView would have WDA and the other some external technology (BSP, JSP, etc) to host the Flash/Flex content. Not tight integration, but you could potentially use Portal Eventing to at least communicate events.

Upload a .xls file in web dynpro abap

Hello,
I want to upload a .xls file into a internal table in web dynpro abap (Netweaver 7.31).
The file is not delimited, is not an csv file.
In my view I have an fileUpload UI Element with the attribute data is un attribute type XSTRING and the following function module are not in my system:
HR_KR_XSTRING_TO_STRING
ALSM_EXCEL_TO_INTERNAL_TABLE
How can I upload the file with this format?.
Thanks in advance.
Xavi

Unless the files are zipped together into one archive file, you have to do them one at a time. Furthermore with the normal browser based fileUpload UI element, you must do them one at a time and the user must manually select each one (browser security limitation).
If you are on 7.01 you can use ACFUpDown to perform multiple file uploads, but there is no file dialog or directory scan so file selection is difficult.
If you are on 7.02 you can use ACFUpdown and it has a multiple file open/save dialog.
If you are on 7.01 you could use FlashIslands to perform the multiple file upload. I have a tutorial and source code sample for this on SCN.
If you are on 7.01 you could also use ACFExecute to run a batch script on the client side that zips all the files and then upload the zip archive.

Window Navigation In Web Dynpro ABAP

In one of our requirements we would have to make use of the suspend plug in Web Dynpro Abap. Would anyone happen to have any other information on this topic. Is there a sample program available which demonstrates the same?
The requirement is that, I have to call an external window (output screen) from my present screen (input screen). While this external window is active, the calling window (input screen) should be disabled. When the external window (output screen) is closed the input screen should be enabled again. I have read that suspend/resume plugs can be used for this. However, I have not been able to figure out how to use them.
As a starting point, it would help if I can find out how navigation between two windows (not views) can be achieved.

You can enable and disable a view at least programmatically by binding the enabled property of all elements to one context variable and setting this to false when you navigate and back to true when you come back.
With these special plugs I haven't worked at time.

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.

Web Dynpro ABAP: Assigning of Conversion Exits in ALV

Hi,
We are currently developing a generic data display application using ALV technology in Web Dynpro ABAP. "Generic" means that the structure of the data is created dynamically during runtime (using RTTS) and that even the contained data elements are created dynamically without any relation to DDIC. The generation is based on metadata like field name, data type, length, decimals, conversion exit.
Our problem is that we were not able to find a way to assign the conversion exit of a data element ("column") in Web Dynpro ALV. Without this feature, no output conversions will take place since the data elements have no relation to DDIC. In the "classical" ALV, this could be easily done using method SET_EDIT_MASK of class CL_SALV_COLUMN.
Is there a similar method in WebDynpro ALV or at least an alternative approach to assign a conversion exit to a column or cell?
Thanks for your help in advance.
Best Regards,
Sven

Hello Sven Hader,
As you said you are generatiing the metadata like field name, data type, length, decimals, conversion exit dynamically.
Can you please let me know how you are diong this?
Meanwhile, you can try this approach to assign a Conversion exit to ALV Table column attribute dynamically.

Adding attachments to workflow from Web Dynpro ABAP Application program.

Hi,
workflow is supposed to start by a Web Dynpro ABAP Application.
The user can attach files to it.
A superior is supposed to review the files and either approve or reject the request.
I tried the following in Web Ddynpro ABAP:
CALL FUNCTION 'EWW_WORKFLOW_START'
EXPORTING
X_TASK = 'WS90000074'
IMPORTING
Y_WORKFLOW_ID = lv_WF_ID
TABLES
X_CONTAINER = lv_IT_CONTAINER
EXCEPTIONS
then followed by:
CALL FUNCTION 'SAP_WAPI_ATTACHMENT_ADD'
EXPORTING
WORKITEM_ID = lv_wf_id
ATT_HEADER = lv_swr_att_header
ATT_BIN = Item_FILENAMEATTACHED
DOCUMENT_OWNER = SY-UNAME
LANGUAGE = SY-LANGU
IMPORTING
ATT_ID = lv_swr_att_id
The Workflow has only one user decision step and one notification Step.
In the user decision step, there is a binding from ATTACHOBJECTS to the task.
But, in the log, you can see the attachment in the Workflow Container of the workflow instance, but you don't see it in the task (neither Inbox nor UWL)
I have checked the binding it is correct. I am getting the attachment in workflow container in '_attach_objects' element. but this attachment has to go to the user decision step, so I am binding the '_attach_objects' of workflow container to '_attach_objects' of user decision step. But the attachment was not going to user decision step.
Could you please let me know where am i doing wrong?
Thanks,
V.Nagaraju

@Ruslim Chang
Sorry to point out but the FM will return the Workitem ID only so there is no problem with the LV_WF_ID variable.
@vundralla nagaraju
Instead of making binding between attachobjects make binding between
WiGroup_ID <---- attachobjects
and then on the next step you try to make biniding in the user decision step by using WiGroup_ID.I think it should work.

Reading Dynamic Table Values in interactive form (web Dynpro ABAP)

Hi All,
I have created a Web Dynpro ABAP application which contains an Interactive Form, That Adobe Interactive Form contains Dynamic table (New rows can be added manually and deleted using a button).
I am not able to read the Dynamic table values in Web Dynpro u201COn Submitu201D.
In the Adobe form I have web Dynpro native button (I am using ZCI), while clicking the native button I need to read the dynamic table values.
How can I resolve this problem.
Thanks and Regards,
Boopathi M

that means, when u add the table instance at runtime, you will also have to add an element to the node that is bound to the table.
probably addNew() mathos may be useful to you.
it appends a new record to the record set.
xfa.sourceSet.dataConnectionName.addNew()
also when on the exit event of the table field, do the following:
var i = xfa.parent.index
$record.rootnodename.tablenodename.data<i>.fieldname = $.rawValue
xfa.host.messageBox($record.rootnodename.tablenodename.data<i>.fieldname)

Search Help on Adobe Interactive Form with Web Dynpro ABAP

Hi All,
I have created Adobe Interactive Form with ZCI type and XML based interface type using Webdynpro ABAP.
I placed a text field USER_NAME on the form ( data element is linked to search help USER_COMP ).
Added Native WD UI element 'Value Help' to form to search for users and changed script
*var fieldName = "INSERT_NAME_HERE*"; to var fieldName = "USER_NAME";
The problem is that when I click on the value help button, nothing happens.
Is any more additional steps required ?
Thanks

Concepts in web dynpro abap

concepts in web dynpro abap? how different is it from abap

hi,
webdynpro is pragramming model for developing ui which are placed in the portal. abap is totally different in this portal does not comes in to picture .
                                   webdynpro is for developing ui elements like buttons. check boxe etc. we ooabap in the webdynpro abap. not the abap concepts. u should have knowledge on oo concepts.
                                        in webdynpro there r again two ways one is webdynpro abap (ooabap) and the other is webdynpro java inthe second way we use java internally.
                        and also there will two engines j2ee and abap engine . one for webdynpro java and the other for web dynpro abap .

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.....
