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.

Reema.

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.

How to do the feild validations in web dynpro abap

dear all,
how to do the feild validations for the screen in web dynpro abap.
thanks,
jyothi.

hi jyothi,
There are diffrent ways of doing validations for fields of screen in webdynpro abap depending on the requirements.
I am giving simplest way of doing this validation(it may fullfil your requirement also)
For e.g you want that without entering value in particular field user should not proceed to submit the data in screen.
DATA lo_message_manager    TYPE REF TO if_wd_message_manager.
DATA lo_api_controller     TYPE REF TO if_wd_controller.
lo_api_controller ?= wd_this->wd_get_api( ).
lo_message_manager = lo_api_controller->get_message_manager( ).
DATA var1 type string.
DATA: node TYPE REF TO if_wd_context_node.
node = wd_context->get_child_node( 'DATA' ).
node->get_attribute( EXPORTING name = ' VALUE'
                         IMPORTING value =     var1 ).
IF var1 IS INITIAL.
    CALL METHOD lo_message_manager->report_error_message
      EXPORTING
        message_text = 'Please enter the value'.
      EXIT.
ENDIF.
Now in above code VALUE is the attribute with whome your input field is bound .So if user doesnt enter any value into it he will get above msg (u have to use message are ui element to use this method)
If you have any other doubt feel free to ask.
regards
Panky

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...
Regards,
Naresh

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.

How to find the BADI'S in Web Dynpro ABAP

Hi Experts,
I'm new to Web Dynpro ABAP. Can any one tell me, how to find the BADI'S for standarad components like i.e DEMO_ROADMAP .Please tell me, steps/procedure to find the BADI'S in WDA.
Thanks ,
Chaitanya
Moderator message: wrong forum, please have a look in the "Web Dynpro ABAP" forum.
Edited by: Thomas Zloch on Jun 18, 2011 4:30 PM

Hi Nagaraju,
There is another fool-proof method to find BADIs while executing a transaction -
1. Goto transaction SE80
2. Select "Class / Interface", type in the class name CL_EXITHANDLER and 'Enter"
3. On the method GET_INSTANCE, create a Breakpoint just after the call to cl_exithandler=>get_class_name_by_interface at the following line -
<i>CASE sy-subrc.</i>
Once the breakpoint has been set, call the transaction you wish to find the BADI for and you will notice that the debugger opens everytime a BADI is about to be called. You could get the name of the BADI from the the value of the variable "EXIT_NAME".
CL_EXITHANDLER is a service class that is called by standard SAP code everytime a BADI is about to be called. So, setting a breakpoint here should let you know exactly which BADIs are called.
Hope this helps!
Thanks,
Rohini.

The same way you do it in normal ABAP. There is nothing Web Dynpro ABAP specific about starting a background job.
There are API Function modules that begin with the name JOB_*. Have a look at the online help for samples:
