Read context node table type

Hi
I have a requirment to read the context node of type cl_bsp_wd_context_TV.
How to read using bol programming?
Any solutions.
regards
John

Hi,
what are you looking for?
* your context node
data lr_node type ref to cl_bsp_wd_context_TV.
* the list of entities
lt_entities = lr_node->table.
* the collection of entities
lr_coll = lr_node->collection_wrapper.
Was that your aim?
There are much more attributes...

Webdynpro reading context into table

Hi Guy,
I havent been able to find anything on this but I am assuming its a very common questions. I apologise in advance.
My question below:
I have a context 0..n
I would like to read this into table type t1.
Context and table are base on the same structure.
I understand I have to use get_static_attributes_ref or table. But I am not sure how to go about getting it and then casting it into type t1
Thanks in advance.

Hi Expets,
I am new to webdynpro Abap, i have developed a small application to set default values for two fields. i want to use code wizard to implement the code. When i click on code wizard icon in application tool bar, i have found lot of option like Method call in current controller, method call in used controller, Instantiate used component ... etc. But i didn't find the option Read Context Node/Attribute. Do i need to do any settings to get that. Kindly suggest. Your help will be greatly appreciated.

Hi,
Check the NW release,
I checked with NW 7.02 - 2 tabs were available.
with NW 7 - only 1 tab was available which you mentioned.
Additional tab (Context ) might have been added after NW release 7.0.

How to modify the data of Context Node of type table in BSPCOMP WB

Hi,
I have context node which is of table type. Now, beofre displaying the table, I have to delete few entries from this context node.
Could you please help me out, how exactly I can handle this?
Component: BP_DATA (Enhanced)
View: MarketingAttributesEOVP
Context Node: ATTRIBUTES
Thanks,
Sandeep

Make use of ON_NEW_FOCUS method of the context node to achieve the same. Get the collection first and then iterate it remove the entities which are not needed and then set the rest of the collection. You can also check standard code for reference.

How to read context node/attribute data of diff UI component of same screen

Hi,
I am new to CRM and as well as BSP, Now the requirement is, at the time of Lead creation, when the end user enters customer code and sales area i need to fetch and display the customer group 1 value( VIP,KAM etc) based on the customer's sales area, ( these are sales area specific values).
but the problem is Customer code is in diff UI component and sales area data is in diff UI component .
1) customer code attribute is in UI component BT108H_LEA, View BT108H_LEA\Detail, Context node is BTPARTNERPROSPECT.
2) sales area fields are in the UI component BTORGSET, View BTORGSET\OrgSetData, Context node is BTORGSET.
3) I have created new field(customer type to display the customer group 1 value "VIP") in UI component BT108H_LEA, View BT108H_LEA\Detail, Context node is BTLEADH.
To display the value in the context node BTLEADH, i need to know the sales area data which is entered in BTORGSET.
Kindly let me know how to read the data which is in diff UI component of the same Lead creation screen.
i written following code in context node BTLEADH, atttribute New Zfield, in get method, but not able solve, please guide me.
DATA: LR_ENT TYPE REF TO CL_CRM_BOL_ENTITY,
             LR_COL TYPE REF TO IF_BOL_ENTITY_COL.
LR_ENT ?= ME->TYPED_CONTEXT->BuilHeader->COLLECTION_WRAPPER->GET_CURRENT( ).
LR_COL = LR_ENT->GET_RELATED_ENTITIES( IV_RELATION_NAME = 'BuilSalesArrangementRel' ).

Hi Gangadhar,
I think i have not clearly explained my requirement, let me put it once again. My requirement is, I have to read two UI component data, validate and display some value in one new zfield which is in one of the UI components.
I need to display customer's sales area specific data like customer group 1 value in that new zfield. for that i need Customer code and as well as sales area data from the screen.
1) customer code attribute is in UI component BT108H_LEA, View BT108H_LEA\Detail, Context node is BTPARTNERPROSPECT.
2) sales area fields are in the UI component BTORGSET, View BTORGSET\OrgSetData, Context node is BTORGSET.
3) I have created new field(customer type to display the customer group 1 value "VIP") in UI component BT108H_LEA, View BT108H_LEA\Detail, Context node is BTLEADH.
As per my understanding, in the context node BTLEADH, GET_METHOD of atttribute New Zfield, i have to read customer code from UI component BT108H_LEA, View BT108H_LEA\Detail, Context node is BTPARTNERPROSPECT and Sales area data from UI component BTORGSET, View BTORGSET\OrgSetData, Context node is BTORGSET based on the values, validate and display the data.
But as per your recent reply you are asking me to write the code in get_property_attribute---division. so i didnt understand.
Kindly clarify if i am wrong.
awaiting for your response.

Read data from table type

Hi everyone,
I am calling a FM BBP_READ_ATTRIBUTES, it exports a line ET_ATTR(Table type) , now in this there is a field VLIST which is an Internal table . and It has entry in it.
Now I require to get this internal table.
I declare in data statement var type tabletype.
How exactly can i retreive this internal table .
when i double clicl on ET_ATTR , it a tabl type but i calls a line type BBPS_ATTR which is like a structure and there is a feild like VLIST which is an internal table .
Please help me to retrieve the data in this internal table.
Reagrds,
Raj

Plz try the following..
FIELD_SYMBOLS: <fs_vlist_tab> type VLIST. " plz give the table type of VLIST
DATA: WA_VLIST TYPE LINE OF VLIST
READ TABLE ET_ATTR INDEX 1. " as you saying it has only one line, read only index 1. o.w. you can read the other lines too as per you requirement.
ASSIGN ET_ATTR-VLIST TO <FS_VLIST_TAB>.
READ TABLE <FS_VLIST_TAB> into WA_VLIST index 1.
* and process your WA_VLIST as requried..

Remove leading Zeros from the mapped context node(Table)

HI,
I have he following requirement:
In the Leave approval application , in the Approver worklist we have the coloumn to display the resuqester's Perner.
The perner starts with leading zeros. We have to remove these leading zeros.
I have refer the following threads:
Removing leading zeros in a column
How to remove leading zeroes of string
and wiki document:
https://www.sdn.sap.com/irj/scn/wiki?path=/display/java/remove%252bleading%252band%252btrailing%252bzeros%252bfrom%252ba%252bstring
but I am not able to create the calculated attribute in the Mapped Node( NWDS is not allowing indicating it is not allowed for mapped nodes.)
Any pointer how I can remove leading Zeros from existing column?
If I create the calculated attribute outside the mapped node then it is taking only the first value of the mapped node.
Please note we do not want to modify the RFC.

Hi,
Thanks for inputs,
Now I created a test application where the original structure is as follows in the View Controller:
1) Context -> Z_Portal_Test_Input (mapped Node/folder) -> IT_Tab_Input(mapped Node/folder) -> Eid(Mapped attribute)
note: this attribute Eid has the values (01, 02,03,04,05)
2)Context -> Z_Portal_Test_Input (mapped Node/folder) -> Output(mapped Node/folder) ->IT_Tab_Input(mapped Node/folder) -> Eid(Mapped attribute)
Now as per your suggestion I created another node like this
Context -> Z_Portal_Test_Input (mapped Node/folder) ->testnode(value node) ->testValue(value attribute)
testnode cardinality is 1..1 and singlton = false
In the Layout
The tablecell editor of one coloumn is mapped to text     Z_Portal_Test_Input.testnode.testvalue
It is expected that this will show the values like(1,2,3,4,5) but it is showing value(1,1,1,1,1)
The code of get method is:
public java.lang.String getTestnodeTestvalue(IPrivateTestpernerView.ITestnodeElement element)
    //@@begin getTestnodeTestvalue(IPrivateTestpernerView.ITestnodeElement)
      String msg =wdContext.nodeZ_Portal_Test_Input().nodeOutput().nodeIt_Itab().currentIt_ItabElement().getEid();
        return removeLeadingZeroes(msg);
    //@@end
the functon removeLeadingZeroes(msg) is implemented as per the wiki link.
What wrong I am doing/ missing....

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.

ABAP: dynamic context node + attribute for DROP_DOWN_BY_KEY

Hello,
I need to create a Node with attributes dynamically and than assign it to a DROP_DOW_BY_KEY element in ABAP.
I create drop down this way:
drop_down_figure = cl_wd_dropdown_by_key=>new_dropdown_by_key( bind_selected_key = 'REPOSITORY.FIGURES' on_select = 'GET_OPERATOR' ).
cl_wd_grid_data=>new_grid_data( element = drop_down_figure ).
ui_container->add_child( drop_down_figure ).
However, here I bind to REPOSITORY.FIGURES. Instead of doing this I need to bind it to an attribute that I create.
I can access wd_context but I am not sure how to create a node in wd_context, then attribute for that node that will contain items for drop down.
bind_selected_key is type of String. If I create a node with attribute how do I cast it to a String so I can pass it to a constructor of a drop down?
Thank you.

How to create a table type context node

Hi,
I am trying to create table type context node. While creating, in the wizard no where I can see the option for this.
Could you please let me know how can I do this?
In one standard component: SRQM_INCIDENT_H, I can see multiple table type context nodes. Not sure how and why?
Thanks,
Sandeep

HI Sandeep,
When you right click on context node and create , a wizard will open. In that Wizard in one sreen it will ask for type of view. There you have to select Table View.

(ABAP) Internal table of type context node (Urgent)

Hi All,
I created a internal table in a view say ABC_VIEW using a context node say ABC_NODE. This is did using following statement:
it_abc type table of if_abc_view=>element_abc_node.
Now I would like to pass this as a exporting parameter to a method in component controller. Kindly suggest how i can achieve this. I tried the following:
it_abc exporting element_abc_node.
But this does not work.
Kindly reply soon.

Anoop
Message was edited by: Anoop Singh Saini

Hi Anoop,
Web Dynpro generates an internal table (and structure) for each context node in a controller's context. Such a definition is local to the controller where the node is defined, since a different controller could have a node of the same name with different attributes. Nonetheless, it is possible to transfer the data of a node to another controller by:
(a) Using a DDIC structure for a context node. The generated structure and the DDIC structure are the same then. The generated internal table is a standard table. If you define one in DDIC or somewhere else, you can use it for typing the parameter.
(b) Transfer the pointer to the node! You can still access it from any other place.
Best regards,
Thomas

Bind Dynamic Table To a Context Node

Hello,
I created an internal dynamic Table. I want to show this table in an ALV-Table. So I want to bind it to a context node.
I create the context node attributes by this:
lr_node_info ?= lo_nd_template_exp->get_node_info( ).
*Type of table type and context type have to be the same
LOOP AT lt_plchar INTO ls_plchar.
clear lv_text.
lv_text = ls_plchar-plchar.
TRANSLATE lv_text TO UPPER CASE.
ls_fieldcatalog-fieldname = lv_text.
ls_fieldcatalog-inttype = 'C'.
ls_fieldcatalog-intlen   = '10'.
APPEND ls_fieldcatalog TO lt_fieldcatalog.
ls_attribute-name = lv_text.
ls_attribute-type_name = 'CHAR10'.
lr_node_info->add_attribute( EXPORTING attribute_info = ls_attribute ).
ENDLOOP.
So I create a fieldcatalog and the attributes at once.
Then I generate the table with this:
CALL METHOD cl_alv_table_create=>create_dynamic_table
       EXPORTING
         it_fieldcatalog = lt_fieldcatalog
       IMPORTING
         ep_table = <fs_data>
       EXCEPTIONS
         generate_subpool_dir_full = 1
         OTHERS = 2 .
IF sy-subrc <> 0.
ENDIF.
* So now points to our dynamic internal table.
ASSIGN <fs_data>->* TO <fs_1>.
* Next step is to create a work area for our dynamic internal table.
CREATE DATA new_line LIKE LINE OF <fs_1>.
* A field-symbol to access that work area
ASSIGN new_line->* TO <new_line>.
Data: copy_table type ref to data.
field-symbols: <copy_table> type standard table.
create data copy_table like table of <new_line>.
assign copy_table->* to <copy_table>.
ok, nice. when i now bind the table to <copy_table> to lo_nd_template_exp it all works fine. But i also want to but the data into the table.
This also works. When I debug, I can see the table filled with the values. But then there's always this error:
Invalid operand type for the MOVE-CORRESPONDING statement.
Ok, I have read, that the types may be not fit. But I don't know why and how i can solve it.
Do you have any ideas?

Hi,
I've the same problem: I must create all attribute of my node at run-time and then create alv.

ENDIF.
Pass context node to ALV
lo_interfacecontroller =   wd_this->wd_cpifc_alv( ).
lo_interfacecontroller->set_data( node_lenght ). " node_lenght is my dynamic node
But I receive this message error:

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 read the context node of used component?

Hi,
I have component called : SRQM_INCIDENT_H. This component has used component - BTSTATUS.
Now, I need to read the context node of the BTSTATUS/UserStatus in GET Methods of Context node in SRQM_INCIDENT_H.
Can you plese help me out.
Thanks,
Sandeep

The component usages can be accessed from the component controller
You should however assure that the context node is present in comp controlelr of the used component.View context nodes cannot be accessed.
if not ,then you need to goto the component BTSTATUS ,add the context node explicitly to comp controller,and do correct bindings to the view context node.
Once you add the context node to the com controller,yo also need to expose it.
go to runtime repository->component_interface->interface_controller->context->right click and select ADD CONTEXT NODE, and add you newly creatde context ndoe of comp contorller here.
Now you cann access it using the code below in your comp SRQM_INCIDENT_H
data:lr_comp_controller type ref to <ur comp controller class>lr_comp_controller ?= me->comp_controller.
    lr_comp_usage ?= lr_comp_controller->get_component_usage( iv_usage_name = '<name of the comp usage as in runtime repository' ).
    CHECK lr_comp_usage IS NOT INITIAL.
    lr_cnode ?= lr_comp_usage->get_context_node( iv_cnode_name = '<the required context node name>' ).
