Exception Handling in webdynpro abap

Hi
I have a function call which raises an exception. How do i handle it?

hi,
In WD4A, Exception handling in FM is same as We do in R/3. You can check sy-subrc after calling the function module.
Also you can raise error message by using web dynpro code wizard(control + F7 ) button:
Select Generate message radio button. You will find number of methods in F4. You can use them as per your requirement
Example :
Suppose you call a FM like this in WD ABAP :
CALL FUNCTION 'F4UT_RESULTS_MAP'
 TABLES
 shlp_tab = t_shlp_tab
 record_tab = t_record
 source_tab = t_HCP
 CHANGING
 shlp = p_shlp_descr
 callcontrol = icallcontrol
 EXCEPTIONS
 illegal_structure = 1
 OTHERS = 2.
Now after this FM, check the sy-subrc value Like this:
if sy-subrc = 1.
<Report message for exception 1>.
elseif sy-subrc = 2.
<Report message for exception 2>
endif.

I dont wanna to display the exception mesage doen the bottom,
Instead of dispalying the exception message, i want to dispaly some other things like confirmation box or dialog box..
How to catch exceptions in webdynpro?
if use try catch finally block in webdynpro,
and in catch block i kept messaeg of popup confiramtion box, it is not been displayed....
Thanks in advance
Shravan

For displaying error in confirmation box, try following code:
Create a eventhandler named as "Exception"
try
//Some statements
catch(Exception e)
IWDControllerInfo controllerInfo =wdControllerAPI.getViewInfo().getViewController();
String dialogText = "TYPE UR ERROR MESSAGE";
IWDConfirmationDialog dialog = wdComponentAPI.getWindowManager().createConfirmationWindow(dialogText,
controllerInfo.findInEventHandlers("Exception"),"OK");
dialog.open();
OR
To display error message at some place other than bottom( which is default), add a UI element named as MessageArea and placed it at the required location in View and trying executing the application.

How to handle events in webdynpro abap

Hi,
can any body explain how to handle the events in webdynpro abap.
i want to know some concepts in general.
Thanks,

Hi Mahesh,
you can create event handlers under the actions tab in you view. evry event handler has an importing parameter wdevent of type ref to cl_wd_custom_event.
you can also create events in your component controller and they can be handled within your views
check cl_wd_custom_event class for details about what all information you get when an event occurs.
for further details you can check out the following links

OnSelect event for a Drop down UI Element in Webdynpro ABAP Select Options

Hi Experts
We have built our UI based on the webdynpro ABAP Select Options. We have a requirement that, when we change the value of a drop down box in the UI, I need to hide some fields. Can anybody help me out in handling of OnSelect event of a drop down box built using webdynpro ABAP Select Options. We are on SAP Netweaver 7.0 EHP1.
Rrgards,
Srikanth.
Edited by: Srikanth Kancherla on Apr 29, 2010 10:43 PM

Hi Srikanth,
as you seem to be already aware, the component is dynamically built.
so you would have to enhance the code that builds the element and insert a reference to a new action (enhancement) that could handle the onSelect event.
What is it about this that you particularly want help with?
Cheers,
Chris

DMS Document not getting created thru Webdynpro ABAP Strange Problem

Dear all,
My requirement is that I have a Webdynpro ABAP application sitting on SAP Server1 and I am having a FileUploadUI Element in there for uploading files and we have SAP Server2 with the DMS configured. So, what we have done is we have an RFC in SAP Server2 and we are calling it from our webdynpro ABAP application sitting on SAP Server1. And we are calling BAPI_Create2 with all the necessary parameters in this RFC to create the DMS document with the file from webdynpro ABAP application. But its not working. I am passing the Presentation Server File Path of the File to the BAPI_create2.Even if I write the file to the application server of SAP Server2 and then pass this file path to the BAPI_Create2 then also it doesn't work but when I execute this RFC locally in the SAP Server2 with the presentation server file path It executes successfully.
I don't know what I am missing.
Please help.
Thanks and regards,
--Sonal

Dear Thomas,
Suppose I have got the file copied to the application server in SAP Server2 using datasets from WDA in SAP server1.
Now I have an RFC say ZFILE_UPLOAD in SAP Server2 for which we have made an SAP ABAP RFC Connection from SAP Server1. In this RFC I am calling BAPI_create2 using the application server filepath(of SAP Server2) in docfile parameter along with ur suggested destination then also it doesn't work. Gives an error that "error in storing and checking file" i.e. Error 253.
One more query how to handle the file upload of different file types say I am uploading a pdf file from my webdynpro abap application in SAP server1. Then I get the xstring and pass it to ZFILE_UPLOAD and convert it into binary and write it there in SAP Server2 using datasets. Is it possible to upload any kind of file and then creating the DMS document out of it?
and how to call this RFC?
Thanksn and regards,

How to call the RFC from R/3 to SRM, when we use webdynpro abap? (Urgent)

Hello
We use SRM Server 5.5 with classic scenario.
We want to call RFC in R/3 from webdynpro ABAP.
How can we do that?
We are developing the web report using webdynpro abap.
So we need some of R/3 data such like PR(EBAN)and PO(EKKO,EKPO).
When user choose the search parameter, report diplay the Shopping cart, PR and PO data on webdynpro. So we call the R/3 RFC to display the PR, PO data.
But I tired to call the RFC in R/3, We could not call it.
How to call the RFC from R/3 to SRM, when we use webdynpro abap?
Thank you,

SAP uses META Function modules in SRM to get data from R/3 back-end.
For getting Purchase requistion data, use the function modules ->
META_REQUISITION_CHANGE Change purchase requisition
META_REQUISITION_CREATE Create Requisition
META_REQUISITION_DELETE Delete/close purchase requisition
META_REQUISITION_GETDETAIL Display requisition details
META_REQUISITION_GETITEMS Display requisition items
META_REQUISITION_GETRELINFO Get Releasease Info for requisitions
For getting Purchase order data, use the function modules ->
META_PO_CREATE Create purchase order
META_PO_DELETE Delete reservation
META_PO_GETDETAIL Display purchase order details
META_PO_GETITEMS Display purchase order items
META_PO_GETRELINFO Display purchase order release information
Hope this will definitely help. Do let me know.

Anonymous user Unbale to access an WebDynpro ABAP iView

Hi,
I have developed an application using webdynpro ABAP and integrated that into portal.
For this webdynpro application i have to create an iview, assigned it to a page, assigned this page to a custom role. I also set Authentication to anonymous for the page and iView. Assinged the custom role created to anonymous Group.
But while running it i am getting an error "An exception occurred while processing your request. Send the exception ID to your portal administrator. Exception ID 04:55_25/10/11_0047_14739050"
When I checked the log, it shows the error as "Deprecated scope of type SERVERSESSION_AT_LEAST_ONE_APP_SCOPE is used! Please replace the usage of scopes with new
mechanism based on "Cross application session communication API".
I also checked the note 1031159 and changed the configurations accordingly but getting the same above error.
I am on EP7.3 version.
Please guide me to move further successfully in showing the webdynbpro abap applicaiton to anonymous user.
Thank you.

Hi,
I'm also working on EP7.3 and R3 WD4A integration. But I just can't find any WD for ABAP from whithin EP7.3 wizard.
I tried to create the WD4A iview by right-clicking a PCD folder and then "New"->"iView"->"iView from remote source" to get a search screen. I choose a system alias (point to bk web as), use "*" as application id, and pick "WebDynpro for ABAP" as the application type.
However, I always got "Nothing found. Change your search criteria."
I did do some activation work on backend R3 SICF setting. I'm able to directly access web dynpro via http://mywebas.domain:8000/sap/bc/webdynpro/mywd....
If you're using the same scenario, please let me know anything I missed or any other special setting.
Thanks

Error Handling in Inbound ABAP Proxy with EOIO

Hi,
The scenario
I have a File to ABAP Proxy scenario and since the requirement is that the messages have to be processed in a single queue in the SAP system (i.e. EOIO), the sender file channel was configured to be EOIO. This ensures that all messages that enters the SAP system are put in a single queue and then processed one after the other.
The Issue
Now if one of the messages that enter SAP system fails during the processing in the ABAP program, the queue gets stuck and all messages after that go into a scheduled state. And one has to manually clear the errored message in order to continue processing the other waiting messages.
The Question
I know this is a default behavior in an EOIO scenario, however is there any way in which if a message fails in the ABAP program then one can automatically push it out of the queue and keep processing the other messages after it ?
Thanks
Bharath

As a general rule I only use EOIO when there is a possibility of dependancy between messages (message 1 must be first and finsihed before message 2 starts). Assuming your just moving the errored message asside, I would assume that EOIO should be just EO.
Alternatively, change the ABAP proxy to handle the error and return a clean status. Exception handling (try/catch) should be used were ever dangerous code is being used.
If alerting in the proxy end point is to much trouble - change your proxy to a sync scenario return the error to PI and fire alerts from there <- I think this should be avoided but it will work.
The main point is the exception handling so that the proxy fails "gracefully".

I don't think you quite understand how hibernation mode works.
"The state of a computer is stored into its main memory, which is also called RAM. When a
computer is powered off, the contents of this memory are irremediably wiped out. Hiberna-
tion works in the following way: before being powered off, the computer saves all the con-
tents of the memory to a ﬁle on the hard disk drive. On wake up, data stored in this ﬁle is
read out and restored to the memory. Therefore, the RAM contents are the same before
and after the hibernation process, and the state of the computer is also the same. The
saved ﬁle is named sleepimage, and is located in the /private/var/vm directory. Hi-
bernation is sometimes also called “software suspend” or “suspend to disk”.
The default suspension feature of Mac OS X, called sleep works in a different way. When
entering sleep, every subsystem of the computer is shut down, except the main memory
which is still powered. This process preserves the contents of the memory, and allows the
computer to wake up quickly. However, a sleeping computer still consumes a small
amount of power. Sleep is sometimes also called “hardware suspend” or “suspend to
RAM”.
Apple introduced the safe sleep feature in Mac OS X 10.4.3 for the Powerbook HD line of
laptops. This feature is a variation of the default suspension behavior. The main memory is
still powered during the sleep, but the contents of the memory are also saved to the disk at
the beginning of the operation. The saved ﬁle will only be used if the laptop runs out of bat-
tery power while sleeping, in order to restore the original state of the computer.
This safe sleep feature is what makes hibernation possible in Mac OS X 10.4.3 and above."
Quoted from *Deep Sleep v. 0.7 documentation*
