Enhancement of Standard Webdynpro Component ( Component Usages )

Dear All,
There is a standard WDC_MAIN. It uses many sub components WDC_SUB1, WDC_SUB2, WDC_SUB3.
The problem here is I need to access the context node information of all the sub components ( WDC_SUB1, WDC_SUB2, WDC_SUB3. ) in the main component WDC_MAIN.
<<<Reason for the need to access context nodes in sub component:
I need to collect some fields from various views of various subcomponents into one view of my Main Component. I think this can be done by enhancement implementation where I can create a new view>>>
I can access the nodes of sub components only if the context node in the component controllers are marked as Interface Node. But I cant edit the sub component, because it is a standard SAP provided component.
Solutions that I am trying:
1. I tried to create enhancement implementation and tried to achieve this... but I dont know for some reason SAP doesnt allow to enhance the context node as Interface node.
2. I tried to copy the standard component to Z component, but another risk here is that, this main component is referenced else where and it is difficult again to give reference to this new Z_ component.
Kindly guide me on how to achieve this.
Thanks in advance!!!
Regards,
Sur.

Hello,
Using enhancements, create a context node and a an interface method so you can pass the contexts that you need over this method.
Or you can try to do an external mapping to you context like in the ALV component.

Enhancement in standard webdynpro Screen

Hi,
We have a requirement to add a new field in the layout of the standard webdynpro component
FPM_OIF_COMPONENT for the E Recruitment portal.
Please let us know if this can be done by enhancing the standard WD component.

Suvarnamathy

Hi,
Its possible using WDA Enhancement framework.
However you need to identify
1) The correct WDA component that you need to enhance ( right click on view in browser and look for technical details )
2) Look for the view that you need to enhance.
3) Look for the node in which fields inside this node are bound
4) Look for the DDIC structure/table to which this node is bound
Once you identify all above four points , you need to start enhancing in this order
1) Enhance DDIC Structure/table with new fields
2) Enhance WDA Component by pressing CTRL+F4 and create an enhancement implementation of WDA Component
3) in the view, enhance the node first
4) add the needed UI element in the layout and bind it to the node attribute
For more information refer :

Enhancing Standard webdynpro component

Hi friends,
I have never worked on enhancing standard web dynpro components,
Now i have got requirement, In SRM webdynpro component i have to place Custom Label and Custom Hyper Link, when i click on that hyperlink, one pop up window shud be open, can any please guid how to enahnce this standard webdynpro component
Thnx

Hi,
To Enhance any standard compoenent, and specially a "VIEW" just follow the below steps:
1. Go to SE80, Give the Component Name and press Enter
2. Go to the Desired "View"
3. Click enhance button (ICON Like spiral,6th from left to right of Application toolbar)
4. A Pop up will appear asking your Coposite Enhancement name and Enhancement Implementation name. Create "NEW" on both the occasion.
Now for UI Enhancements:
a) Click the "ROOT UI Element container" , right click add the custom UI elements and assign Property values as per your requirement( like binding,text,action etc.,). It is just like adding UI elements in Z-Compoent.
b) Create actions wherevr required
For Coding Level enhancements:
Here, for all the methods which are in the standard compoenent will have "PRE" and "POST" Exits. The difference is "PRE" Exits will render before calling the actual code and "POST" Exit will render after rendering the actual code.
Note: Till Enhancement Pack (EHP3) we had only PRE & POST Exits. And Now on from EHP 4 and More we do have an option "OVER WRITE" Exit.
Apart from Exits, we can create our own Events/event Handlers. These Event Handlers will work only for the enhancements.
We Can write our own logic in the newly created event/event handler.

Hi Kumar,
By using Enhancement Framework you can do this.
How can we add a new field to the Standard Webdynpro application?

Enhancing a standard component - Table Cell Variant

Hi Forum,
I am trying to enhance the standard WD component /SAPSRM/WDC_UI_SC_DOTC_BD view V_SC_DOTC_BASIC in SRM 7.0 .
The requierment that for certain condition the Quantity cell in a row should be read only.
Carried out the following steps:
1. Created an enhancement
2. In the standard table column ITEMS_TABLE_QUANTITY [Columns] , removed the standard inputfield.
3. Added two cell variants ZITEMS_TABLE_QUANTITY_CV1 [CellVariants] and ZITEMS_TABLE_QUANTITY_CV2 [CellVariants] first one contans a text view and second contains inputfield. Variant key for first one is DISPLAY and for second one is EDITABLE.
4. Enhanced the method WDDOMODIFYVIEW with below code:
**Read the ITEMS table
DATA lo_nd_items TYPE REF TO if_wd_context_node.
DATA lt_items TYPE wd_this->elements_items.
DATA ls_item LIKE LINE OF lt_items.
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lv_disable_quantity TYPE wd_this->element_context-enable_quantity.
DATA lr_table_column TYPE REF TO cl_wd_table_column.
** navigate from <CONTEXT> to <ITEMS> via lead selection
lo_nd_items = wd_context->path_get_node( path = `COMP_CONTEXT.ITEMS` ).
lo_nd_items->get_static_attributes_table( IMPORTING table = lt_items ).
lr_table_column ?= view->get_element( 'ITEMS_TABLE_QUANTITY' ).
LOOP AT lt_items INTO ls_item .
    IF ls_item-catalogid EQ 'VEP_Staples_D0'.
      lr_table_column->set_selected_cell_variant( value = 'DISPLAY' ).
    ELSE.
      lr_table_column->set_selected_cell_variant( value = 'EDITABLE' ).
    ENDIF.
ENDLOOP.
But even after the condition is true ALL cell i.e. the complete column is DISABLED or when the condition is false the COMPLETE column is enabled instead of enabling disabling ONLY THE SPECIFIC CELL.
Is there a problem with the code in WDDOMODIFYVIEW or something else?
Thanks,
Anubhav

Hi Saravanan
Under ITEMS node I added one more Node(cv_quantity) and one attribute(cell_variant_quantity) with in this node.
And code in WDDOMODIFYVIEW :
DATA lo_nd_items TYPE REF TO if_wd_context_node.
DATA lt_items TYPE wd_this->elements_items.
DATA ls_item LIKE LINE OF lt_items.
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lr_table_column TYPE REF TO cl_wd_table_column.
** navigate from <CONTEXT> to <ITEMS> via lead selection
lo_nd_items = wd_context->path_get_node( path = `COMP_CONTEXT.ITEMS` ).
lo_nd_items->get_static_attributes_table( IMPORTING table = lt_items ).
lr_table_column ?= view->get_element( 'ITEMS_TABLE_QUANTITY' ).
DATA lo_nd_cv_quantity TYPE REF TO if_wd_context_node.
DATA lo_el_cv_quantity TYPE REF TO if_wd_context_element.
DATA ls_cv_quantity TYPE wd_this->element_cv_quantity.
IF first_time EQ abap_true.
lr_table_column->set_selected_cell_variant( value = 'EDITABLE' ).<--Initially ALL cells shoud be editable
ELSE.
lr_table_column->bind_selected_cell_variant( path = 'COMP_CONTEXT.ITEMS.CV_QUANTITY.CELL_VARIANT_QUANTITY' ) .
* navigate from <CONTEXT> to <CV_QUANTITY> via lead selection
lo_nd_cv_quantity = wd_context->path_get_node( path = `COMP_CONTEXT.ITEMS.CV_QUANTITY` ).
IF lo_nd_cv_quantity is BOUND.
lo_el_cv_quantity = lo_nd_cv_quantity->get_element( ).
      LOOP AT lt_items INTO ls_item .
        IF ls_item-catalogid EQ 'VEP_Staples_D0' AND ls_item-number_int IS NOT INITIAL AND ls_item-description IS NOT INITIAL.
          lo_el_cv_quantity->set_attribute(
                                            name = `CELL_VARIANT_QUANTITY`
                                            value = 'DISPLAY' ).
        ELSEIF ls_item-catalogid NE 'VEP_Staples_D0' OR ( ls_item-number_int IS INITIAL AND ls_item-description IS INITIAL ) ."If the condition is not satisfied OR no item is added to that line
          lo_el_cv_quantity->set_attribute(
                                            name = `CELL_VARIANT_QUANTITY`
                                            value = 'EDITABLE' ).
        ENDIF.
      ENDLOOP.
ENDIF.
ENDIF.
Now If I add an item that DO NOT satisfy the comdition to be read only, for that row the quantity is enabled but for all the rows below it quantity cells are DISABLED.
Hope my issue is clear?
Thanks a lot,
Anubhav

Changing the attributes of Standard Webdynpro component

Hi Friends,
There is one table ui element in standard webdynpro component, right now we can select only one row, now i want to select multiple rows, can any one help me how to change this property
Thnx and Regards
Kumar Srini

Hello Kumar,
if this node is statically created in the standard component then you can't change the selection cardinality. By statically created means, if you can see the context node in the Context Tab of the controller.
If its dynamically created, then in the Post-exit method, you can delete this context node and create it again (via coding). while creating you can set the Selection Cardinality to multiple.
Hope this helps.

Enhancement to standard WD component are not reflecting in other systems.

A few months back, an SAP consultant created a couple of enhancements to the web dynpro component DPR_DET_DATA_TASK_O for CPROJECT in ECC (the SAP consultant is no longer available).
The first enhancement transported fine to our quality system
The changes on the transport for a second enhancement did not reflect on our quality system.
Transport did not show any errors.
None of the objects are local objects.
¿Does anyone have any idea of the cause of this problem o what I should be looking for?
Thanks in advance.

Hi,
I've had occasions where texts have not been correctly shown after a transport, and have had to manually regenerate (activate) the WD component in the test/prd systems - when I did that the texts then showed.
Hope this helps,
Chris

Enhancing standard webdynpro components

Hi Experts,
I need to change the layout of the standard web dynpro components. I started enhancing the relevant methods in the component controller with pre, post and overwrite methods but when it comesto the UI, after enhancing the componenet if i go to the enhancement to change the UI it is changing the standard UI. In my case the requirement is grouping the UI elements on the SAP standard Webdynpro components and change the format of the data on the screen.Can you please provide suggestions on how to enhance the web dynpro layout without modifying the layout? Please feel freeto askme for further info on the same.
Thanks alot inadvance,

Ravi.

hallo Ravi,
You can delete the layout and create a new layout with the changes you needed. for example the standard UI consists a group with layout as flowlayout.
You have to delete this group and create the group with same name and change the layout to Matrix layout.

Webdynpro Development Component Callable Object Escalation

Hi,
In gp sequential block workflow using webdynpro development component callable objects When the initiator intiates a workflow ,it is assigned to the first approver.Now if the approver does not take any action within 2 days i want to escalate the task to the second approver.How can i do this escalation?
There is a standard parameter call <b>due date</b>...in action.How can I set this value dynamically from my application..
During escalation , the next approver has to be taken by executing an rfc in the background
Please help....
Thanks,
Shamila

Hi,
You can define a CAF Core application service (implemented in the CAF Core layer) or a background CO (implemented by a J2EE class interface) which can call a RFC to get the next approver and return the next approver's user id as an output parameter. You can use dynamic user assignment in the next action (approval), by selecting the processor as "Filled From Context Parameter" (at the Roles tab in block level) and select the user id output parameter of the background CO/CAF app service CO.
You can get more details on different types of CO at the CAF Tutorial Center @SDN

Calling a webdynpro ABAP component from a BSP...

We have a BSP application. On which we have a tab strip control. Upon clicking on one of the tabstrips, is there a way I can launch and display an output from a webdynpro ABAP component?
Any ideas will be appreciated.
Thanks

Raja,
I tried get the iframe tag
<IFRAME NAME="Frame1" SRC="your_web_dynpro_link.htm" >
</IFRAME>
with the SRC = "<the URL from the web dynpro application>"
Did not work. I am sure I am doing something wrong. In fact it did not work even for a BSP application.
Any ideas anyone?

Access Portal groups in webdynpro ABAP component

Hi Experts,
I have a requirement to access portal group in web dynpro ABAP application and based on whether user is assigned to particular group or not further processing for application will be done.
Are there any UME API or some other API's available to access portal groups in Webdynpro ABAP component?
Thanks in Advance..!!
Regards,
Shruti Shah

This might be a question better suited to the portal forum. The WDA Portal APIs do not have such functionality. You might be able to take the Java Portal APIs and wrap them in a web service so that they are callable from ABAP.

Has anybody created Iview from "Webdynpro Java" component in CE7.1 ?

Hi All,
Has anyone created Iview from Webdynpro Java component in CE7.1.
Because the wizard that appears for creation of Iview has only "Webdynpro ABAP"
component.There is no option to create iview from "Webdynpro Java" component.
Althought in portal content--->Template folder i can see there is also
another template for "SAP Webdynpro iview" which i think is for the Java scenario.
But issue is, its not coming in the wizard.Can anyone tell me how to make it appear in the wizard ? It will be of great help to me.
Thanks and Regards
Ashis

Hi Ashis,
your deployed webdynpros are published under "web dynpro applications". just copy the webdynpro from there and paste it into the portal content section.
