Demo on Adobe interactive forms using WebDynpro for ABAP Part 1

I have created a table ‘ZDEPT’ with just three fields; I will be creating an Adobe form for these three fields and will be updating this table using ABAP Web Dynpro framework.

Go to transaction SE80 and create a web dynpro component ZADOBE’.

Enter the details in the popup window as shown below

Assign a package to the application or save as a local object

You can see Component controller, Interface controller and window being created

Create a View as shown below

Give the view name as ‘MAIN_VIEW’ as show below

You can see the main view being created.

Go to the context tab of the “MAIN_VIEW’ and create a empty node.



Give the name of the Node as ‘Adobe’ and press enter as shown below.

You can see the node ‘Adobe’ being created below.

Create another node under the node adobe as shown below.

Give the name of the node as ‘ZDEPT’ and Dictionary structure as ‘ZDEPT’ and press the button ‘Add Attribute from Structure’.

Select the Fields as shown below and press enter.

You can see the node ‘ZDEPT’ with three fields being created under the node ‘ADOBE’.

Now create an attribute ‘PDF_SOURCE’ under the root node ‘CONTEXT’ as shown below



Give the Attribute Name as ‘PDF_SOURCE’ and the type ‘XSTRING’ as shown below

You can see all the nodes that we have created; your screen should appear like the one shown below.

Go to the Layout tab of the ‘MAIN VIEW’ and create a place holder for the adobe form, Right click on the ‘ROOTUIELEMENTCONTAINER’ select ‘insert Element’ from the context window as shown below.

Enter the details in the POPUP window, give the name of the place holder as ‘ADOBE’ and type ‘InteractiveForm’ as shown below.

You can see the placeholder ‘ADOBE’ being created, check the CHEKBOX enabled in the property list, this is a required entry for an interactive form, (an activex control ‘Active Control Framework’ will be automatically downloaded on to the client from the server when the web page is first called). Increase the height to 500px and width to 500px as shown below.

Click on the button in the property list for the property ‘pdfSource’ and select the node ‘PDF_SOURCE’ from the context window.

In the property List for ‘template Source’ property give the name of the adobe form ’ZADOBE’ that we will be creating during this session and double click on it.




In the POPUP window, give the adobe form interface name ‘ZADOBE’ as shown below and press on the ‘Context button’ as shown below.

Select the Node ‘Adobe’ from the context window as shown below.

Save the application as local object.

Press the button ‘Save’ to save the main view.

You can see the Adobe form application with our web dynpro context node ‘ZDEPT’ being mapped to the context of the Adobe form in the Data view tab.

Just Drag and Drop the ‘ZDEPT’ Node on to the form, in the subform tab of the object make the content as ‘Flowed’ as shown below

Drag and Drop ‘Text’ from the Library pallet and enter the text as you wish

Drag and Drop the Submit button on the form as shown below




Just select the event click* and language JavaScript and run at client (No coding is required)

Now save and just activate the Form and the interface as shown below.

Go to the properties page of the form and double click on the interface ‘ZADOBE’ you can see the ‘XML Schema’

You can see the ‘XML Schema’ interface (You can have three types of interfaces ‘Abap dictionary interface, Smart form compatible interface and XML interface) for interactive forms using WebDynpro you have to use the XML Schema interface.

Press the back button to go back to our web dynpro application.

Now we are back to our web dynpro application.

Select the window ‘ZADOBE’ as shown below

Drag and Drop the “MAIN_VIEW’ on to the window

Go to the ‘Main View’ layout tab and select the node ‘ADOBE’ and in the property list Under Events click on the create button for the event ‘onsubmit’ as shown below



Give the name of the action as ‘CLICK’ and press enter.

Go to the Actions tab of the ‘MAIN_VIEW’ you can see the Action ‘Click’, double click on the action ‘CLICK’.

You can see the Method ONACTIONCLICK. Here you can code your business logic, you can call a BAPI or a function module based on the requirement. We are going to code for inserting the values into the table zdept, the values will come from our adobe form.

Copy the below code and paste it in the method.

method ONACTIONCLICK .

data:
Node_Adobe
type ref to If_Wd_Context_Node,
Node_Zdept
type ref to If_Wd_Context_Node,
Elem_Zdept
type ref to If_Wd_Context_Element,
Stru_Zdept
type If_Main_View=>Element_Zdept .

data wa_zdept type zdept.

* navigate from to via lead selection
Node_Adobe = wd_Context->get_Child_Node( Name = IF_MAIN_VIEW=>wdctx_Adobe ).

* navigate from to via lead selection
Node_Zdept = Node_Adobe->get_Child_Node( Name = IF_MAIN_VIEW=>wdctx_Zdept ).

* get element via lead selection
Elem_Zdept = Node_Zdept->get_Element( ).

* get all declared attributes
Elem_Zdept->get_Static_Attributes(
importing
Static_Attributes = Stru_Zdept ).

wa_zdept-DEPTNO = Stru_Zdept-deptno.
wa_zdept-DNAME = Stru_Zdept-dname.
wa_zdept-LOC = Stru_Zdept-loc.

insert into zdept values wa_zdept.

endmethod.

Your Screen should look like the one shown below.

Now Save and Activate the Webdynpro.

Create a Web dynpro application as shown below. Just right click on the node ‘ZADOBE’ and from the context window select createàWeb Dynpro Application.

Enter the Application name as ‘zadobe’ as shown below.

Save the Web dynpro application as local object



Go to the ‘MAIN_VIEW’ Actions tab and keep a session break point in the code, to just see if our code is being executed when we submit the data from the adobe form.

Now we will test the application, right click on the node zadobe and select ‘test’ from the context window.

Logon with your credentials; give your username and password

You can see the Adobe form that we have designed, enter the data as shown below and press the submit button. (As I said earlier an activex control will be installed on to the client machine, you can see the activex control in the internet explore go to the menu: ToolsàInternet optionsàgo to the programs tab àPress button Manage add-ons.

You can see an activex control named ‘SAP ACF’, if you don’t have this control you will not see this page: Note you need to have adobe acrobat reader 7.1 installed, I have used version 9, the activex control was not working properly so down graded my adobe reader to 7.1)

Press F8 to continue.

You can see the entry in the table ZDEPT being updated.
