Replicate ME52N create attachment and attachment list in Web dynpro

Dear Experts,
Please can someone provide sample code and 'How to' steps to replicate ME52N create attachment and attachment list in Web dynpro?
I've looked at FILEUPLOAD and FILEDOWNLOAD in Web dynpro and this seems suitable for only 1 file attachment.
Many thanks, Jas.

Hi ,
If your are having a UI like ME52N and you want an attachment feature in each row, I have below suggestions:
Suggestion 1: If you use ALV
Add a column in list of type Xstring or which ever suits your document specificatio
Add a Button on the ALV for attachment,
On click of the button you can Popup a browse window and user can select the file.
The content of the file can be stored as Xstring for that Line item.
Suggestion 2: IF you use Table UI element
Add an attreibute to context node of type Xstring
In the Table set, you can set FIleUpload as the editor for this column.
I hope it helps.
Regards,
Sumit

Hi Gurprit,
A null value is being passed at runtime. Make sure that you enter values when filling in the form.
Also check for the cardinality of the nodes being used. You can also initiliaze your value attributes as follows:
In wdDoInit() method:
wdContext.currentNodeAElement.setValueA("");
Context is as follows:
RootNode
|____NodeA
        |_____ValueA
Hope it helps.

data sources and Attribute lists need to be maintained in GUI but these can further be used for Segmentation in Web UI using the Graphical Modeler.
hey main thing is that when we design all the things our out put is reflected in both interface & most important thing is that 90% of our customization done in gui.only web_ui related customization done in web_ui.

Window size, and navigation issues with Web Dynpro and GP

I have a Web Dynpro application which navigates to other Web Dynpro applications. I also need to integrate this application into a GP. When I create a process that calls the Web Dynpro app, two things I've noticed are:
1. The window size presented in the GP process is too small, and there is no way to scroll to see the rest of the app. How can I change the initial size of the Window to show the entire application? This is an absolute show stopper...
2. Other functionality is made available to the Web Dynpro app by navigating to other Web Dynpro applications. Outside of the GP, this works correctly. However, from within the application when started via a GP, I get the following error when I try to trigger an action that will lead to a navigation event:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Cannot navigate via outbound plug CreatePdf of view TestView because there is no navigational link attached to it
at com.sap.tc.webdynpro.progmodel.view.View.navigate(View.java:541)
at com.sap.tc.webdynpro.progmodel.view.View.navigate(View.java:462)
Any ideas? Do I have to manually instantiate the various components when the root Web Dynpro app is called from a GP?

Update: this was my mistake - I had neglected to configure all the view containers in the WebDynproCO window, which was generated by adding the GP interface to the component. All is well.

Drop down list in web-dynpro abap

Hi friend,
i want to drop down list in WEB-DYNPRO abap kindly give me one example .
regards
vikash

Suppose you have created a DropDownByIndex on your screen & bound its "Texts" attribute to a context attribute by name DROPDOWN then you can put the below coding into your WDDOINIT method to fill the values to be displayed:
METHOD wddoinit .
DATA: lv_node TYPE REF TO if_wd_context_node,
        lt_texts TYPE if_main=>elements_dropdown,
        wa_texts TYPE if_main=>element_dropdown.
lv_node = wd_context->get_child_node( name = 'DROPDOWN' ).
wa_texts-application = ' '.
APPEND wa_texts TO lt_texts.
wa_texts-application = 'MS Word'.
APPEND wa_texts TO lt_texts.
wa_texts-application = 'MS Excel'.
APPEND wa_texts TO lt_texts.
wa_texts-application = 'Notepad'.
APPEND wa_texts TO lt_texts.
lv_node->bind_table( new_items = lt_texts ).
ENDMETHOD.
Suppose you are using a DropDownByKey & bound the "Selected Key" property to the context attribute by name TEMP then you can proceed as shown below to fill the dropdown with values:
data: lr_node_info type ref to if_wd_context_node_info,
        wa_value_set type wdr_context_attr_value,
        lt_value_set type table of wdr_context_attr_value.
lr_node = wd_context->get_child_node( name = 'NODE' ).
lr_node_info = lr_node->get_node_info( ).
wa_value_set-value = '1'.
wa_value_set-text = 'One'.
insert wa_value_set into table lt_value_set.
wa_value_set-value = '2'.
wa_value_set-text = 'Two'.
insert wa_value_set into table lt_value_set.
wa_value_set-value = '3'.
wa_value_set-text = 'Three'.
insert wa_value_set into table lt_value_set.
lr_node_info->set_attribute_value_set( name      = 'TEMP'
                                         value_set = lt_value_set ).

Advantages and dis advantages of web dynpro java

Hi Guys,
May i know what are the advantages and dis advantages of web dynpro java?
Regards,
Madhu

Hi Madhu,
Web Dynpro (WD) is a proprietary web application user interface technology developed by SAP AG and exists in a Java (Web Dynpro for Java, WDJ or WD4J) and an ABAP (Web Dynpro ABAP[1] , WDA) flavor. Both have in general the same functionality, but usually one flavor is improved after the other, so temporary one flavor is more advanced than the other. Hence, the decision for one of the two flavors shall be based on organizational and business circumstances, but not on functionality.
WD follows an adapted MVC pattern and a model driven development approach ("minimize coding, maximize design") with a large number of dedicated hooks in generated code to place custom coding. It is intended for business applications that shall follow standardized UI principles, connect to backend systems and be scalable.
Main advantages of Web Dynpro over other technologies
typed access for design time checks, e.g. navigation links and messages are accessed via types instead of string keys like in JSF
diverse services for backend access, like aRFC, JEE and Web Service data models
integration with SAP Interactive Forms by Adobe, which are interactive PDF forms, during design (same IDE) and run time (data sharing)
integration with business process management and business rules management (since NetWeaver CE 7.1 EHP 1)
designed to support development big scale applications by adding multiple grouping layers on top of Java packages (DCs, SCs, products)
runs on different clients e.g. web browser, mobile device, widget engine
comes with a big collection of UI elements providing a wealth of functionality and only have to be configured but not programmed
Main disadvantages
proprietary, running only on SAP servers
less flexible due to support for multiple clients (i.e. custom html is not possible). To reduce the limitations, several measures have been taken. For example, WD supports so-called "islands" for e.g. flash applications that enrich the Web Dynpro UI element collection by rich UI elements. This disadvantage doesn't seem so serious but in fact basic features that user expect to receive cannot be implemented (e.g. coloured rows in table, colours in general, advanced aligning of simple UI elements (due to nonexistence of more complicated ones), selecting multiple rows in tree-like tables (this is due to preserving basic concept of WD) and many more). Having the flash feature means that developer completely avoids WD UI (And thus cannot use other features).
rendering speed in browser for larger tables (>1000 rows)
The designtime and runtime environment is part of SAP NetWeaver 7.0[2] (also known as Netweaver 2004s) and following releases.
The name comes after the original Dynpro library, whose name meant "Dynamic Program".

Pradeep Kumar

Creating pdf and attaching to email

Hello,
I am trying to write a script to help manual work and am stuck at below point:
When click save in SAP I get pdf document generated (nhremote). What I would like to do is to somehow automatically save it on my drive and attach it in the new email that is generated after each save.
Script end:
'session.findById("wnd[1]/usr/btnSPOP-VAROPTION1").press - SAVING the changes and pdf is generated at this point. takes some time to popup.
'Set MyApp = CreateObject("Outlook.Application")
'Set MyItem = MyApp.CreateItem(0) 'olMailItem
'With MyItem
'.To = "[email protected]"
'.Subject = "Subject"
'.ReadReceiptRequested = False
'.HTMLBody = RDD
'End With
'MyItem.Display
is there any way I can put action to save and attach saved file to the email? Also please keep in mind that the script is looped and it does this for many documents. Since NHREMOTE to generate pdf usually takes sometime and is a popup window I'm afraid it can be very complicated and mess up easily.

This script starts the TAC SE38 and loads the Report PROGDELE. It exports the report as PDF and sends the PDF file via e-mail to hugo.bambi.
All you have to do, to try this script, is to customize your SE38 view, that the shortcut Shift+F5 ist set to File.ExportPDF.
You see, it is possible to save a PDF from SAP and to send it as e-mail attachment . Also you see it is possible to handle SAP dialog windows. And it should be not a great problem to do this steps in loop for more than one document.
Let us know your result.

RoboHelp - how to create Number1 and Number list styles?

In RoboHelp 11, I have multi-level lists and normal lists. The multi-level list will continue numbering after a break in the list, like so:
1. step one
2. step two
break
3. step three
If I want step three to start a new list, I go to the HTML and manually add a start="1" attribute. The normal list will start over at 1 after each break, and if I want it to continue I need to add a start attribute for wherever I left off.
What I want is what I use in FrameMaker: a list style for Number1 that I can add when I want to restart lists, and a Number/Number_next for continuing where I left off, without having to manually alter the HTML. I feel like I'm missing something because I can't find an option to create a list like this in the CSS editor, and I can't figure out what to add manually to the CSS file in a text editor that makes RoboHelp recognize what I want it to do. But obviously the option exists because the multi-level list and the normal list exhibit both behaviors that I want.

In RoboHelp (or HTML), there is no feature like you have in Frame. Both Multilevel list and regular HTML lists require you to set the numbering after you break.
An alternative way of working may be to not create real paragraph but to end line feeds pressing Ctrl+ENTER. This won't break the list numbering while you can add multiple lines.
Kind regards,
Willam

Create image of XSTRING data and display it in Web Dynpro

Hello,
I am trying to dynamically display an image in a Web Dynpro ABAP Image-Control. The problem is that the data is stored in the DB as XSTRING and I can't find a Method for example to create a new object in the MIME-Repository of the data which is read out of the DB at runtime.
I have already converted the XSTRING into w3mime-Format with the function module RSFO_XSTRING_TO_MIME, but the Control needs a string of a url to display the image (for example to a MIME-Object of the component or a link to a file on the ITS).
Is there somehow a possibility to do this?
Thanks for your help,
Kolja

Creating and Edit Order in Web Dynpro (seperate window or view?)

Hi,
I have just done with Web order creation in web dynpro and is going to start on Edit now. Should I have a seperate window for Edit or should I put it together in the same window as Create order?

Hi Jackson,
Most of the time for such kind of requirements it is generally prefer to have a seperate view for edit and that is being called using the plugs from the main screen.
The flow will be like this:
View 1 (main View having data, Fieds for editing are disabled) -
> Fires Plug to Edit view -
> Edit View ( With all fields enabled which you want for editing).
In kind of a design the main advantage is, you can directly keep the required nodes in the component controller and map these nodes in main view and edit view, both. Without even caring for any data flow.
Data flow will be automatically be taken care by the component controller. The only one thing which needs to be handled is the UI elements enable and disable property. Because in the case of the main view you need to keep the disbale property of most of the UI element as True (as you don want user to edit anythign in this main view). In the edit view the disable property of same UI elements will be set to False, as used can edit any thing in this edit view.
If you keep this kind pf approach one more added advantage is that you can pass various parameters in the plug function. So if you want to handle something on the bases of sone flag etc then you can pass those parameters in the plug method.
However, as replied earlier, the decision is purely based upon your requirement. If the requirement is to show the edit screen as a Pop-up then you can help it!! Go with it..
I hope this will solve your issue. Please revert back if you need any other information.
Thanks and Regards

I am not able to create a callable object of my web Dynpro application

Hi,
I have my Portal server installed with NW2004S and with other components as follows.
·WAS 7.0 SP9
·EP7.0 SP9
·CAF 7.0 SP9
·VC 7.0 SP9
But now my webdynpro application is not reflecting in web Dynpro Component(GP Interface) during the design time, when I am trying to create a callable object.
So please can you suggest what is the problem and how I will get it corrected.
Regards,
Paresh.

Hi Aliaksei,
I had created a complete CAF application which was working fine. Then the server got crashed and i lost everything.So then i again installed the server and upgraded it to SP7.But than i was not able to see my web dynpro application while creating callable object. So i created another instance in the server at the base level(SP4) and i was able to create callable object.
There is no problem in the webdynpro application.I have added runtime library referece to my project : sap.com/cafeugp~api and also implemented the Interface IGPWebDynproCO in my component.
So i dont know where i am going wrong while i am upgrading the server.
Regards,
Paresh.
