Interactive ALV in webdynpro ABAP

I have a requirement where in, i have to show a report in ALV and on lead selection from ALV list i need to show another screen with some UI elements.Since i use view container elemnt it doesnt have required properties.
Please help me to find out existing methods which can help me making the ALV list interactive to show another screen.
I searched in the forum but didnt get the required solution.
Thanks in advance.

Naveen,
The basic Concept of using the ViewContainerElement is to bring the View of another component into the calling component. That means, the actions and methods for the table or any UI Element will still exist inside the View of the Called Component, the ViewContainerElement is just a Place Holder for this Called View.
Let us consider an Example:
v_view1 --> Calling Component
v_view2 --> Called Component
v_view1 will have the ViewContainerElement (V_CONT) binded with the inbound plug of v_view2 window.
v_view2 will have all the actions, methods, events to handle and manipulate the data.
So, anytime, there is a lead selection of the data, the events from v_view2 will be active to handle the leads.
To understand this, you need to debugg the v_view2 methods, anything which you have already created.
Please let me know, whether I've addressed your query properly.
Regards,
-Syed.

Interactive chart in Webdynpro ABAP

Hi Experts,
I would like to use this thread to discuss on SAP's recommendation to develop Interactive chart in Web dynpro ABAP .
Correct me if Iam wrong ,
1) Business graphics can not be made interactive.
2) With Gantt UI element ( I couldn't find documentation ).
3) Interactive Chart in FPM ?
4) Interactive Chart using FLEX Builder ?
5) HTML Island ? Though not available for Customers with lower version of SAP ?
What is SAP's Road map w.r.t Interactive chart in Webdynpro ABAP ?
Regards,
Karthi M

Hi Stuart,
Business graphics can be made interactive only with click action.
Gantt UI , Iam not finding any proper documentation. Cursing SAP for that.
If you are lucky enough to have latest version of SAP. Try with SAP UI5 which has got very good interactive capabilities of graph.

Uploading data from Interactive form in Webdynpro ABAP

Hello All,
I am uploading data from an Offline interactive form to an ABAP WebDynpro application. Form is first downloaded, data is filled and now I am trying to upload the form to another WebDynpro application. Form DataSource is mapped to Context node with same data structure. However when I upload the form, form data does not pass automatically to specified context node.
Do I miss any important step in between? I am on SAP NetWeaver 2004s SP10.
Thanks,
Nitesh Shelar.

hi,
the data is automatically passed to the context when the "interactive form" UI element is there in the view.
when you just upload the pdf, just like that, it will treat it like a PDF file, not an interactive form....
try using the same interactive form which you used to create the offline form.
i hope this helps,
regards,

Hierarchical sequential display in ALV for webdynpro ABAP

Hello,
I am doing an ALV report WebDynpro for abap. I have a situation where I have to display Open Items and all the partial payments in the ALV report. In short. In summary, I have to display a Hierarchical Table of data which two different structures of data, but linked and displayed together.
The only information I have to go about this is [Table as Hierarchy|http://help.sap.com/saphelp_nw2004s/helpdata/EN/3e/904b2624534e0db707c7314a5e1e9d/frameset.htm] in SAP Help.
If you have any pointers for programming a Hierarchical Sequential report in Webdynpro alv that would be great. Any classes, methods etc I can use or , how I can do bindings to the context etc...
Thank you for all your help.

Hi Asha,
If you want to use ALV then refer to this [thread|ALV display] and check Uday's reply. It will give you some idea.
If you want to use table to show your data, the refer this [article|https://www.sdn.sap.com/irj/sdn/abap?rid=/library/uuid/7a89b067-0801-0010-8192-a9896a60938e].

Drop down in ALV for Webdynpro ABAP

Hi Experts,
I was trying to implement one Web dynpro ABAP application that will show one ALV and ALV will content one dropdown so that user can select data from the drop down. Addtion to that, my dropdown should have data based on another column of ALV.
I have followed one article which is available in Net.
At the end of development, ALV is displayed with dropdown. Also dropdown has data binded. However, no data is visible in dropdown.
I have created one context node having four dictionary element and one elemt for dispplaying the dropdown.
In the DoInit method of view, i have written below code:

EXPORTING
    value = lr_drdn.
CALL METHOD lv_value->if_salv_wd_table_settings~set_read_only
EXPORTING
    value = abap_false.
I am still finding the answer why data in drop down is not visible. However, I can select by clicking dropdown and blank elements (since data is not visible) can be selected.

Hey
i am using the same code except i have just modified little bit the select statement to restrict the number of entries.
and also besides writing the code in wddoinit i have added the compenent usage of alv component and added the node
having the structure ckst and after that deleting the dictionary reference to add the attribute valueset in both places
component controller and view controller and mapped them and mapped the data node of interface controller of comp
usage to this node in comp contrlr.
and adding the view container and embeding table view of alv comp there.
that's it
and here is the code which is almost same as yours except small change in select statement.

Dropdown List in Adobe Interactive Form Using Webdynpro ABAP

Hi Pals,
In my scenarion I need to list the Rating Code in the Dropdown list box of the Interactive Form.
Form Created by using SFP transaction
Not XML Schema interface
Passing the values to the Form by using the default function module that which created automatically while creating the Form
Am binding the Field and also binding for the list Item. Even though the values are not listing.
$record.sap-vhlist.<Field name>\.DATA\.FIELD.item[*]
I have followed the above format , but no use ...
Field Name : rating_code
$record.sap-vhlist.RATING_CODE\.DATA\.FIELD.item[*]
Field Name : value
$record.sap-vhlist.VALUE\.DATA\.FIELD.item[*]
but it is not working for me, will appreciate if some one really help me to fix this.!!!!
Thanks & Regards
Andy.

For the form buttons to work on-line in your WebDynpro app, you need to change the PDF form to be Dynamic:
     if(firstTime){
          // We need to set the PDF to be Dynamic, for the form JavaScript code to work
          IWDPDFDocumentInteractiveFormContext pdfContext =
          WDPDFDocumentFactory
          .getDocumentHandler(wdThis.wdGetAPI(), "InteractiveForm")
          .getDocumentContext();
          pdfContext.setDynamic(true);
In this code segment, "InteractiveForm" is the UI id.
I was able to get that far, but I although I add subforms dynamically via javascript, the mapped WebDynpro context node doesn't pick up any new elements.
ie: if I start with two WD context elements (0..n) cardinality, then add a third via the form JavaScipt button, I see changes only in the two context elements when I submit. A third context element isn't created or populated.

ALV in Webdynpro ABAP

Hi,
When ALV is in edit mode, there are four default actions (buttons) in the toolbar of ALV - 'Check', 'Append row', 'Insert row' and 'Delete row'. I just want to know that when 'Append row' is clicked, Which event is triggered.
I need this to set some default values in the cells of newly inserted row.

Hi Anoop,

Hiding fields and subforms on interactive form for WebDynpro ABAP

Hi All:
I'm new to using interactive forms and I am creating a new form for material request. I need to hide selected fields based on the value of other fields. I also need to hide subforms the same way.
I have added the formcalc script to hide the field which apperas to work. But is I remove the field value, the hidden field is not made visible. This also applies to the hiding of the subform. I have tried the code at different events but no luck. If I enter 'KINC' in the plant field, the KINC_TAX_IND is visible. But if I remove or change the value, the KINC_TAX_IND is not being made visible.
Below is the code I am using:
if ( PDF_DATA.#subform[0].PLANT.value == "KINC" ) then
PDF_DATA.#subform[0].KINC_TAX_IND.presence= "visible"
else
PDF_DATA.#subform[0].KINC_TAX_IND.presence= "hidden"
endif
if ( PDF_DATA.#subform[0].PLANT.value == "" ) then
PDF_DATA.#subform[0].Subform2.presence= "hidden"
else
PDF_DATA.#subform[0].Subform2.presence= "visible"
endif
Thanks for any help.
