Binding of different context nodes in BSP WD Workbench

Im creating a new View .
How can i bind a new attribute node in this view to context node of <U>component controller</u>( not of custom controller)?
Edited by: Oleg Agranovich on Oct 27, 2008 3:07 PM

HI,
just like you would with a custom controller. It is the same method call in the CREATE_XXX method of the context class.
Just substitute the iv_controller_type variable with CL_BSP_WD_CONTROLLER=>CO_TYPE_COMPONENT
owner->do_context_node_binding(
        iv_controller_type = CL_BSP_WD_CONTROLLER=>CO_TYPE_COMPONENT
        iv_target_node_name = '<<CUCO_NODE>>'
        iv_node_2_bind = <<node>> ).

Reading Attributes from different context nodes in the same view

Hi,
I have added a new field as part of an enhancement for Trade Promotions. This field is a checkbox and part of the context node TRADE in the view TPMOE/HeaderEOF. This field will be checked or unchecked using a logic in the background.
The logic will be based on an attribute (Fund Plan ID) which is part of another context node FUNDPLAN in the same view.
How can I read the attribute of FUNDPLAN context node in TRADE context node?
A sample code will be quite helpful as I am new to CRM 2007.
Thanks,
Abhishek
Edited by: Abhishek Periwal on Oct 16, 2008 2:35 PM

Hi Abhishek,
If I understand your question correctly, you would like to access the Fund plan ID (in a different context node) in the getter setter methods of the check box attribute which you have added.
The code snippet mentioend by sudeep works perfectly fine when you are making any checks in the view implementation class. But since you are in the getter setter methods of the context class, this doesnot work as "me" always refers to the class instance in which you are present.
Now in this case what you need to do is :
1) create an attribute <view_controller> in your context class. Here the context is TRADE. The type of this attribute wud be same as the view controller class CL_TPMOE_HEADEREOF0_IMPL
2) Go to the view controller class and redefine the method
DO_VIEW_INIT_ON_ACTIVATION. This method is called only once when the view is loaded for the first time.
3) In this method, put the following code
me->typed_context->(Trade)->[view_controller] = me.
by the above code, you are setting the newly created attribute to the view controller instance.
4) The next step would be, go back to your getter setter methods or what ever it may be, try referring to the Fund plan ID by the code snippet mentioned below
data: lr_entity type ref to cl_crm_bol_entity.
lr_entity ?= me->[view_controller]->typed_context->[the context node in which the fund plan id is present]->get_current().
lv_field_value = lr_entity->get_property_as_String( **pass the field name here ).
This should definitely resolve the problem.
Thanks,
Vinay

How to use attributes from different context nodes in one view?

I am VERY new to the concept of CRM and currently working on creating an alternate version of the BP_HEAD_SEARCH. With help from SAPPRESSs book 'SAP CRM Web Client' i was ble to create my own simple Z-component.
However after going back and forth the book and the forum (including this [article|https://wiki.sdn.sap.com/wiki/display/CRM/Howtoaddanexistingfieldtoasearchpageofadifferent+component]) i was not able to find a solution to my problem. My current search uses BuilHeaderAdvancedSearch as context node for searching. But the search should also be able to use attributes from BuilActivity, which is directly related to BuilHeader. I can't seem to find a way to get attributes from BuilActivity into the search window of my component without having to change SAP-Standard.
Is this really the only way? Please advise on possible code and insertion point.

Any suggestions?

How to read the value of a field belonging to a different context node in GET_I method during runtime

I want the read the value of a field,'LCSTATUS' belonging to context node 'BTADMINH' in the GET_I method of the field, 'ZZFLD000008' belonging to context node,'ZBTACTIVITYH'.
In the context node class of context node 'ZBTACTIVITYH',I have created an instance attribute,GR_OWNER type ref to context class.
I get the following error in the line - lv_act_status = Lr_entity->if_bol_bo_property_access~GET_PROPERTY_AS_STRING( 'LCSTATUS' ).
'An exception (CX_CRM_CIC_PARAMETER_ERROR) occurred Message no. TPDA430'
I have used the below code.

Hi,
LCSTATUS is not an attribute of the BTADMINH structure. It is read using the relation to the status object
BTADMINH-> BTHeaderStatusSet-> BTStatusHCurrent-> ACT_STATUS.
Try reading the ACT_STATUS of object BTStatus as given below.
        data: coll   type ref to if_bol_entity_col.
       data: entity type ref to cl_crm_bol_entity,
                     lv_act_status TYPE string.
       entity ?= current.                                                               "BTADMINH entity.

Values retrieved by OVS not binded to the context node

Hi all gurus,
In SRM 7 I'm working on an ABAP web dynpro (/SAPSRM/WDC_DODC_CT) which is intended to show a document's header custom table. In the unique view of this web dynpro, the user can see the table (made up by custom fields) and can add or remove a line.
I created dinamically a pair of OVS search help for some of the fields of the table, in this way (method WDDOMODIFYVIEW):
* insert: Object Value Selector for ZZ_PROLE_R3 and ZZ_LIFNR_R3
      DATA: lo_tabnode        TYPE REF TO IF_WD_CONTEXT_NODE.
      DATA: lo_tabnode_info   TYPE REF TO IF_WD_CONTEXT_NODE_INFO.
      lo_tabnode = wd_context->GET_CHILD_NODE( name = 'THCUS' ). "the custom table node
      lo_tabnode_info = lo_tabnode->get_node_info( ).
      CALL METHOD lo_tabnode_info->set_attribute_value_help
        EXPORTING
          name = 'ZZ_PROLE_R3'
          value_help_mode = 131 "ovs mode
          value_help = 'OVS'
      CALL METHOD lo_tabnode_info->set_attribute_value_help
        EXPORTING
          name = 'ZZ_LIFNR_R3'
          value_help_mode = 131 "ovs mode
          value_help = 'OVS'
and these Object-value selectors seem to work properly: the user can trigger them and the selection populates correctly the related field, in the selected row, of the table.
So we could say that apparently, everything seems ok. BUT...
...if I then SAVE the document, or simply change to another view and come back, the new entries added via search help disappear.
It's like there's something missing (a binding?) on the "lower" level...But I don't understand what's the point.
Otherwise, if a value is entered directly by hand by the user, the new row remains persistently (that is to say, direct fill by the user populated correctly the table view AND related fields in the buffer table). Is there something I'm missing?
This is the third - and last - phase in my OVS method (ON_OVS_R3_ROLE):
WHEN if_wd_ovs=>co_phase_3.
*   apply result
        IF ovs_callback_object->selection IS NOT BOUND.
******** TODO exception handling
        ENDIF.
        ASSIGN ovs_callback_object->selection->* TO <ls_selection>.
        IF <ls_selection> IS ASSIGNED.
          ovs_callback_object->context_element->set_attribute(
                                 name = `ZZ_PROLE_R3`
                                 value = <ls_selection>-zz_prole_r3 ).
        ENDIF.
Help and suggestions are highly appreciated.

HI,
I found the clue, but basically I have no idea on why it happens
This is the point: when I select a possible value from a select list in the OVS help, then the corresponding value(s) on the tables are filled BUT no CHANGE BADI is in this case triggered. Odd thing is that even if I select the field populated by the search help and press ENTER, the BADI isn't triggered.
Standard behaviour, which happens anytime I enter a value "manually", triggers the CHANGE BADI automatically (I can see in debug that the stack of the calls contains a fire_event_update, that's probably the clue).
So I guess the point is how to make a selection from a select list in OVS be equivalent to a value enter manually, so that we could generally say that anytime an input is filled - no matter if by OVS or "by hand" - the underlying CHANGE BADI is triggered.
Any help or suggestion is really appreciated,
thanks.

Reading attributes of different context nodes

Hello,
I want to read attributes of BP_DATA/TaxNumberList Node: BUILHEADER from Node BUILTAXNUMBER.
I have tried all without success. In GENIL Browser they are not related.
What can i do?
Best Regards

Hi
I checked in the Model Browser. Seems 'BuilTaxNumber' has 'BuilHeader' as parent.
Can you validate once in TCODE GENIL_MODEL_BROWSER for ONEORDER Component set.

Is it possible to bind the elments with context node dynamically?

Hi All,
Is it possible to dynamically bind elements with context nodes?
In other words, at runtime, can we change the binding of an Inputfield to another context. Or a table to programmatically bind to another table?
Regards,
urbashi

hi urbashi.......
      it is possible..
       you should first pass the id of he ui element and then bind it.
       for ex:
         if there is an input field, you can get the attribute that is bound, using cl_wd_input_field->bound_value.
         if you want to set an attribute, use cl_wd_input_field->bind_value.
         the first one will give an idea of how a valueshould be given.

Data transfer between 2 views with context nodes

Hi all,
I'm working for the moment in CRM 7 with the BSP WD Component Workbench.
I have a small exercice (just to learn more about the webclient ect) and I have some problems.
I created 2 views:
- Worklist (List with all workflow items available for user)
- Workflow (When choosing a workflow item in the worklist, the workflow will be executed, or whatever...)
Now, I have a internal table with all workflow data and when I click on one workflow item, I want to give this data (from one record) from my internal table in a Context node tot the seconde view.
But how?? I realy don't know.
Can someone help me with this?
I created a custom controller
Should I use model nodes or value nodes?
what next? How can I fill this nodes with the data?
Any examples?
Thx!
Hans

Reading the Context Node in the same Component

Dear Gurus,
I have made enhancement to standard view and functionality is working fine.
Now i need to read the different context node (Different view) from the same component.
I try to do the way Webdynrpo read the context node but here there is Wizard and i stucked :-(.
Can you plz suggest or post small code to read context node.
Regards.
****Poorna****

Hi,
If those two views are assinged to one viewset in runtime repositoty, you can read the secod view by following code:
lv_viewname = me->get_viewarea_content( 'Upper' ).      " here(me =view1)
IF lv_viewname IS NOT INITIAL.
    lr_viewctrl = me->get_subcontroller_by_viewname( lv_viewname ).
    IF lr_viewctrl IS BOUND.
from here you can read the context nodes.

Unable to bind elements to context

Hello all,
As part of POC, I have created a table and have to push some dummy(hard-coded) data into the table. I have limited experience with ABAP OOPS.
To implement the code, I have the reference to context node. But, there are methods to bind element/elements/structure to the node and not to add element to node.
Now, i tried to populate the element and add it to internal tab and bind it to context node. It creates an entry in table but the data is not displayed.
The code is given below:
method WDDOINIT .
DATA lo_nd_zviposhead TYPE REF TO if_wd_context_node.
DATA lo_el_zviposhead TYPE REF TO if_wd_context_element.
DATA ls_zviposhead TYPE wd_this->element_zviposhead.
TYPES: BEGIN OF ty_itab,
          node_elements TYPE REF TO if_wd_context_element,
        END OF ty_itab.
DATA: element_itab TYPE table of ty_itab,
        wa_element type ty_itab.
navigate from <CONTEXT> to <ZVIPOSHEAD> via lead selection
lo_nd_zviposhead = wd_context->get_child_node( name = wd_this->wdctx_zviposhead ).
@TODO handle not set lead selection
    loel_zviposhead = lo_nd_zviposhead->create_element( )._
      loel_zviposhead->set_attribute( name = 'FIELD1' value = '0.601.010.005')._
      loel_zviposhead->set_attribute( name = 'FIELD2' value = 'Ordered')._
      loel_zviposhead->set_attribute( name = 'FIELD3' value = '4')._
      loel_zviposhead->set_attribute( name = 'FIELD4' value = '14')._
      loel_zviposhead->set_attribute( name = 'FIELD5' value = '0')._
      waelement-node_elements = lo_el_zviposhead._
    append waelement to element_itab._
<< the above code which is underlined is repeated to add 3 more sets of data >>
lo_nd_zviposhead->BIND_ELEMENTS( new_items = element_itab SET_INITIAL_ELEMENTS = abap_true ).
The result is a table with 4 elements but empty.
Kindly help me to achieve the result. If any better alternative to push hard-coded data to table, do let me know.
Thank you.
regards,
Sharath

Hello,
To add elements to the context, Please have a look at the following code:
method WDDOINIT .
" define a local structure type with all the attributes defined in the context
types: begin of ty_element,
           category type string,
           tooltip type string,
           date     type d,
           end of ty_element.
data:
    node_datasource type ref to if_wd_context_node,
    element type ty_element,
    elements type standard table of ty_element.
node_datasource = wd_context->get_child_node( name = `DATASOURCE` ). "get the reference to the node
element-tooltip = 'Birth day'.
element-date     = '20100627'.
element-category = 'ONE'
append element to elements. "add element to the internal table elements
element-tooltip = 'Birth day'.
element-date     = '20100627'.
element-category = 'ONE'
append element to elements. "add element to the internal table elements
node_datasource->bind_table( elements ). "bind to the node
endmethod.
This works!
above code is for adding several elements at once to the context node using bind_table.
If you want to create one element and add it to the context, use the following code:
lo_el_<node> =
lo_nd_<node>->create_element( ).
lo_el_<node>->set_attribute( name = 'attr_name' value = 'attr_value')
lo_nd_<node>->bind_element(
new_item = lo_el_<node>
set_initial_elements = abap_false ).
Hope this helps!

Srilatha

Using One Context Node's Info in the Setter of Another

I am very new to WebUI.
I have a view. In its context, it already uses context node BUILHeader . I need to create a field based on BP_NUMBER info in BUILHeader and place the derived information on the screen.
I created a new context node that has a field DerivedValue in it. I think I am supposed to populate it in it's P_Setter. How do I make he information from BUILHeader available to my setter.
I think this is simple, but I'm new. so I need a good code example here.
Thank you .
...Mike

Hi
Like Amar pointed out if it is possible pleae make sure that the field is also in BUILHeader context nide itself.
If you want it to be in different context node then
you can use me->typed_context -> "<context_node name >"
create an attribute "typed_context" pointing to the context class.
"<context_node name >" --- Here you can replace the any of the context node which is present in your view!! you can use
this anywhere inside the view. Hence you will be able to access other context nodes as well within the purview of the view.
Thanks

Query in Context Node

Hi all,
Can anyone please tell me as to when we go for creating a New Context Node.
Regards,

Where to create new context nodes in the component workbench should be clear. The Wizard on view generation or the wizard after right click on context nodes.
Creating new entries in the context nodes during runtime can be done everywhere. I experienced problems doing it in DO_HANDLE_DATA.

How to bind UI Element with Context Node Attribute Element

Hi,
I'm building my view dynamically in the wdDoModifyView method.
Is it possible to bind a "TextView" element to a specific element of an attribute node?
Scenario:
Node_Employees
|
+- Attribute_Code
|
+- Attribute_Name
Node Contents:
Employees
|
+- Code: 1, Name: Employee 1
|
+- Code: 2, Name: Employee 2
|
+- Code: 3, Name: Employee 3
I need to do something like binding a TextView UI element to the "Name" attribute of the element #2, what would result to show "Employee 2" on my view.
How can I do this?
Thanks in advance,
Geraldo.

Hi Saravanan,
First I populate the context node and it won't change during view's lifecycle. After that, I build my view and bind the TextView UI elements to the node context attributes elements.
If the node has 10 elements, I will build 10 TextView UI elements and bind them to each attribute element.
Regards,
Geraldo Brígido.
