WDA: TreeByNestingTableColumn and ALV in webdynpro for ABAP

Hi,
1) I am trying to implement a tree with nested structure and multiple columns. I am using RecursionNode in the context and UI element TreeByNestingTableColumn. I am not able to figure out how to make a distinction between the key and parent key. In TreeByKeyTableColumn, we use key and parent key to differentiate. Is there any link which explains how to implement TreeByNestingTableColumn in Webdynpro for ABAP? (I got a link for webdynpro for java though).
2) Can ALV be used to implement a tree structure instead of using Table with TreeByNestingTableColumn or TreeByKeyTableColumn? Then I would be readily able to use ALV features like sort etc. If it can be used is there any link which explains how to do it in Webdynpro for ABAP?

Hi Srinivasa,
I can answer the first point. If you use a recursive node and TreeByNestingTableColumn, there is no need to have a rowKey and parentRowKey, since the recursion with the context already defines the hierarchy. As far as I know someone posted a blog that explains how to use the TreeByNestingTableColumn in Web Dynpro Java. I don't have the link available, but this blog would be good place to start. The implementation in WDA and WDJ is pretty much the same here.
Kind regards,
Thomas

put the code in the wddoinit method and it should work.
have a look at this article..

Eventing in Portal page between Team Viewer and Custom Webdynpro for ABAP

We are trying to implement a new Portal page that contains a Team Viewer Iview and a custom Webdynpro for ABAP iview.
The idea is that the when a manager select one of his direct report in the Team Viewer, the custom Webdynpro for ABAP would pick up the selection_changed event and retrieve the data for the selected employee.
We followed the instruction provided by SAP in note 1112733 and it worked in our development environment. When we moved the iviews to our testing environment it stopped working.
I also used the Diagnostic Iviews provided by SAP and I get the same result: Works in Dev, does not work in QA or in Prod.
We also followed the troubleshooting steps of note 945516 and it still did not help us. We can not find a difference in our system set up.
We are therefore looking for pointers as to what could be our problem.
Thanks!
Edited by: Benoit Fortin on Feb 20, 2009 2:28 PM

Problem was solved internally:
The reasons the eventing worked in Dev and not in QA or Prod, was that we had a different level of patch for ESS/MSS between instances, which I was not aware of.
Dev was on ESS/MSS version 600 SP14 and QA and Prod was on a different level. Once we implemented ESS/MSS SP 14 accross the board, everything was good.

WebDynpro for ABAP Vs Java

Hi all,
I have recently started learning Web Dynpro for ABAP.
I have worked in WebDynpro for Java.
1)I wanted to understand pros and cons of WebDynpro for ABAP and Java.
2)What are the functionality that are available in Web Dynpro for Java but not in Web Dynpro for ABAP.
3)What should be preferred when considering performance issues - WD for ABAP of Java?
Any Web Log or Link in this context will be helpful.
Thanks a lot,
Rashmi

Hi,
OOPs ABAP uses Classes and Interfaces which uses Methods and events.
If you have Java skills it is advantage for you.
There are Local classes as well as Global Classes.
Local classes we can work in SE38 straight away.
But mostly it is better to use the Global classes.
Global Classes or Interfaces are to be created in SE24.
SAP already given some predefined classes and Interfaces.
This OOPS concepts very useful for writing BADI's also.
So first create a class in SE 24.
Define attributes, Methods for that class.
Define parameters for that Method.
You can define event handlers also to handle the messages.
After creation in each method write the code.
Methods are similar to ABAP PERFORM -FORM statements.
After the creation of CLass and methods come to SE38 and create the program.
In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
see the links below, Understand them and start developing.

Webdynpro for ABAP - Textdirection top - bottom ???

Hi all,
is there any ui-element which enables textdirection top -> bottom or supprts HTML tags to realize this simple requirement ????
Thx !!!

I understand this, but if you implement right->Left and Left->Right you should also think about top->bottom & bottom->top, also there is a FormatedTexView with some HTML support but this has no style and can't be embedded as a Celleditor into the ALV... And also the fixed colors for ALV Cells i don't understand why there should be a limitation of colors for cells in CL_WD_TABLE_COLUMN=>E_CELL_DESIGN
I really like and enjoy the WebDynpro for ABAP concept but sometimes i feel really sad for such limits like i mentioned because that is basic layout stuff.....

Is DD/MM/YYYY supported in webdynpro for abap application

Hi All,
We are using 2 different time statements one developed in webdynpro for java and other in webdynpro for abap.date format in java is DD/MM/YYYY but in webdynpro for abap is DD.MM.YYYY.
is DD/MM/YYYY supported in webdynpro for ABAP application or even if user enters DD.MM.YYYY can we convert that to DD/MM/YYYY so that we will maintain uniformity in both the applications
Thanks

Issue regarding cell action in webdynpro for abap alv

hello gurus,
       i have one requirement in webdynpro for abap alv.i have one alv table in that i have one coloun employee name.
for that i have provided F4 help and that is editable field.if i select value from F4 help it is getting value correctly and it is showing properly at the same time it is allowing values entered manually insted of from F4 help.but as per my requiremnet it should not allow any manually entered values.how can i get this functinality. i am not aware indepth od WDA.
could you go through my isssue and could you revert me some solution.
thanks in advance.

Hi,
   I dont think this is possible because when you can change the value using F4 then it would obviously be
   possible to enter manually.
   You can try using a drop down instead because in drop down you cannot enter values manually,
   But this would be good if the values that can be shown in drop down are very low, if the values are more
   then again user will face problems selecting values.
   Else you can try out what srinivas suggested, But dont know whether we can have two cell editors at a time
   inside a single cell of ALV. Please post the answer if you have found any other way to do it.

In webdynpro for ABAP alv table issue

hello gurus,
                  i am new for webdynpro for ABAP.i strucked at one point at designing time.anybody could you suggest me on this.
thanks in advance.
let me explain my scenario first.
in my webdynpro for ABAP developement i have one alv table having ten fields.i am featching the data for eight fields from one Ztabale and updating , for rest of two fields we need to fill after displaying output using the respective F4 help. Right now these two fields are in input editable mode.now i am getting the values successfully from F4 help and at the same time it is allowing MANUAL ENTRIES also but as per my requirement it should not allow any manual entries . for this i have made these two fields are in readonly mode as like as rest of fields to avoid the MANUAL ENTRIES but at this time i didnot get any F4 helpfor those two fields.
so how can i achive my goal in this thing could any one suggest me.
my final conclusion is we need to get only F4 help values into those two fields . it should not allow any manual values at any point of time.
best regards,
babu

Webdynpro for abap and single sign on

I have developed application using webdynpro for abap and it is working fine. The problem is we can not get sso working . i.e. even though we configure SSO but still getting the screen asking to login into
sap web application server again
This is the 1st wda we have developed and not sure whether we can apply SSO with wda as it is find with webdynpro for Java. The basis team has gone thru all the configurations and could not understand why it did not work.
Thank you in advance.

Thank you for your quick response.
1. Is the portal certificate added to Backend ? - yes
2. Is the Backend and Portal in Same Domain ? - yes
3. Are you accessing the Portal using FQDN ? - No, we use web dispatcher to redirect. But the same result if we access Portal using FQDN.

Diff between BSP and WEBDYNPRO FOR ABAP?

Hi All,
can anyone let me know the Difference between BSP's and WEBDYNPRO FOR ABAP.
Regards,
Ravi

Hi Ravi,
In truth, Web Dynpro contains many of the enhancements than BSPs....like built-in value-help and select options...... they
will become standard in Web Dynpro. But these can also be added to BSPs also.
There are several architectural differences between BSP and WDA. WDA has some advanced features but more restrictive framework compared to BSP.
WDA is stateful only. While BSP supports both stateful and stateless programming models.
WDA doesn't aloow us to use our own custom HTML, JavaScript or other controls. To provide compatibility the rendering logic is completely hidden from the developer.
On the other hand, BSP has no such restrictions and allows an extreme level of custom rendering. This makes BSP a perfect platform for applications that require pixel-perfect layout or specialized UI elements.

Webdynpro for ABAP - Popup apearing for userid and pwd

Hi Experts,
We have implemented ESS and gone live. Now we have created one custom application in webdynpro for ABAP and attached with portal.
Initially there was a problem, the application was not getting executed because of system configuration, then I have configured the host name, port number correctly. Then the iView is getting loaded in the portal.
The problem is, when I am trying to access the iView, the popup apearing for the user id and password. This is happening only the webdynpro abap application, this is not happening for all sap standard iViews.
Could anyone help me with this issue?
Thanks
Jay

Hi Jayanthi,
as you had mentioned this is not happening for sap standard iViews(do you mean simple transaction iViews for which you have used a system alias, which was the same you had used for ABAP web dynpro iview)?
Of courese ESS iViews works with their own JCOs which is no way helpful or connected with wd ABAP.
So I believe if your SAP id and Portal id are different(or if they are same but SAP Logon ticket is not configured properly) then only it woudl ask for the authentication again- for Wd ABAP to work fine, only the connector property and WAS to tbe configured in the system object(aka system alias) used for ABAP iview. Now once you enter the login credentials, it is working fine right, then could you please test the user mapping under the user you are logged in, select the alias that you had used while creating the abap wd iView and provide userid/password here, then run the wd ABAP application, it definitely would work.
N.B: if you had provided the credentials once, then it woud be stored in the browser cache, so if you perform the user mapping in user admin, log off from portal, close all your browser windows, then clear cache,(cookies etc). then login to portal, run the wdABAP application, I am sure this would work(it worked for me!!!).
Thanks,
Jakes.

Any difference between webdynpro for java and webdynpro for abap ?

Hi all:

Webdynpro for ABAP and Portal Integration

Hi Experts,
we created a WebDynpro for ABAP application for portal. The application will modify/update few fields in backend sap HR table PA0006 (infotype 6) . The end user (portal user) should be able to update his data in backend with the iview created on this application.
I have below two questions in my mind.
1. Do we need portal eventing for this? It's a single iview in portal which will fetch and update his data through this WebDynpro for ABAP application.
2. It is for 10 countries of almost 1000 users (with same userid in portal and backend). How can I make sure that the enduser updates and fetch his records only. The SSO is already set up between Portal and Sap ECC system. Do I need to again pass the enduser portal id to the sap in coding to fetch and update the data or sso will take care of itself.
Thanks
Ajay

1. Do we need portal eventing for this? It's a single iview in portal which will fetch and update his data through this WebDynpro for ABAP application.
Answer: If you use, for exemple ITS to access this Webdympro, you will not need any action on portal for sure. Actually you will just need actions on portal, if you want to make some customization on portal side. If you want just show the Webdympro how it is, your action are all on backend..
2. It is for 10 countries of almost 1000 users (with same userid in portal and backend). How can I make sure that the enduser updates and fetch his records only. The SSO is already set up between Portal and Sap ECC system. Do I need to again pass the enduser portal id to the sap in coding to fetch and update the data or sso will take care of itself.
If you access via ITS, te custome will acess the backend with the user you have set on the SSO or user-mapping. The portal there is nothing to do in this regards, you must just take care of this on backend.
Please evaluating the answer you are contributing for the SDN keep growing.

Webdynpro for ABAP and Workflow

Hi All,
I have few applications developed in WebDynpro for ABAP. Now I have the following requirement in one of my application. I am creating some new entries in the custom table based on the user inputs and actions. Before creating a new entry some one needs to approve that. Once the approval is done I have to create a new entry.
I came to know that this can be achieved using workflow. I have no much idea on workflow. Could someone suggest me how I can achieve that please?
Thank You,
