Approach Context node in code

Dear forumpeople,
At this moment I try to set an attribute with this code:
wdContext.currentContextElement().set...
But, how should I set an attribute which is set in a node?
We tried:
wdContext.current***Element().set*("");
But this is not working because of a NullPointerException.
Any ideas?
Regards,
Adri

Adi,
That code applicable for context attubutes not for context Node Attributes.
Follow this code,
Adding Values to Context Node:
Syntax:
IPrivate<View Name>View.I<Node>Element x = wdContext.node<node>().create<node>Element();
WdContext.node<Node>().addElement(x);
x.set<AttributeName>("Value");
Example:
for ( int i=0;i<=10;i++){
IPrivateBusinessGraphicsView.ITestElement x = wdContext.nodeTest().createTestElement();
wdContext.nodeTest().addElement(x);
x.setMyAttr("100"+i);
x.setMyAttr("2000"+i);
This must be solve your Problem

How to populate the context nodes based on an event

Hi All,
I am having a basic problem. I have created a new Webdynpro Abap application. Here, in the main view, i have define a text view as well as a table. I have created context nodes A and B in component controller. The attributes under A are A1 and the attributes of B are B1,B2, and B3. I have also created an action button C in the same view. These have been mapped to the context nodes in the main view. A1 is mapped to the text view and B1, B2 and B3 are mapped to the table.
My requirement is as follows. When user Clicks on execute, i want to use the value A1 from the text view in a function module and return the values to B1, B2 and B3. B1, B2 and B3 are multiple values mind you.
I have successfully executed the function module within the WDONACTIONC method. How to i accomplish this Basic Task. Please Help
Best Regards

Hi Mazin,
Step 3 is as follows...
Say you have a context node, you have to bind this node with table UI element, now this node must contain some context attribute which you have to bind with your columns of table. now say name of context node is cn_table. now what you have to do is get data from FM in the internal table..........
now move data by using move corresponding or by looping depending on requirement to an internal table which has fields with the same name as that of name of your attributes... this is imp to display the data...... now you can bind this internal table with context node using code below.......
data lo_nd_cn_table type ref to if_wd_context_node.
data lo_el_cn_table type ref to if_wd_context_element.
data ls_cn_table type wd_this->element_cn_table.
data it_table type wd_this->elements_cn_table.
data wa_table type wd_this->element_cn_table.
data it type standard table of t005t.
data wa type t005t.
** navigate from <CONTEXT> to <CN_TABLE> via lead selection
select * from t005t into TABLE it.
loop at it into wa.
 wa_table-ca_one = wa-land1.
 wa_table-ca_two = wa-landx.
 wa_table-ca_three = wa-natio.
 wa_table-ca_enable = abap_true.
 append wa_table to it_table.
 endloop.
lo_nd_cn_table = wd_context->get_child_node( name =
wd_this->wdctx_cn_table ).
* get element via lead selection
 lo_el_cn_table = lo_nd_cn_table->get_element( ).
lo_nd_cn_table->bind_table( it_table ).
ca-one, ca_two, ca_three and ca_enable are name of my context attribute......

Read Context Node/Attribute option in webdynpro code wizard not available

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.
Venkat

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 populate a context node on the basis of the values in another node?

Hi,
I have a Webdynpro application which has to run on Portal as well as BlackBerry.
In this application I have a scenario where I need to have a sub node inside a node but as Blackberry doesn't support sub nodes with Singleton value false, I have to use another node for storing the values which earlier wre present in the sub node.
The actual scenario here is that we have two tables A & B. For each row of table A we have a no of rows in table B. This can be easily accomplished for Web Browser but we need to do this for Blackberry.
My question here is that how can i populate the data in table B at runtime using the concept of onLeadSelect. I am not able to fully undersans this concept.
According to my approach I have two a while loop which generates data for table A and inside this while loop I have another while which generates data for table B corresponding to each iteration of the outer while loop. I create the node elements for the rows of the table B and store them in a list and then store this list in a HashMap corresponding to a key formed by combining the values of all the elements of the row of table A.
Now I am not able to understand how can I display this data into table on user slecting a particular row.
Please guide ASAP.
It wille quite useful if you can provide me with some code snippets for the same.
Thanks in advance!
Manish

Hi Manish,
In WebDynpro u can use the onLeadSelect event of table A and do all the processing in that method.Like u can use this method to fill ur context node,which will be the source node for table B. So this way u need not to use any hash map.Fill the source node of table B with data corresponding to ur selected data of table A.
I hope this solution wud help u in solving ur problem.

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?

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,

How to set value from one view to other view's context node attr b4 save

HI all,
My requirement is as below:
There are two views in component BP_CONT.
BP_CONT/ContactDetails    IMPL class
BP_CONT/SalesEmployee   SALESEMPLOYEE    STRUCT.SALESEMPLOYEE
I want to set value from first view to second view's context node's attribute.
i get Sales Employee BP number in ContactDetails view, from here i want to set that value in to STRUCT.SALESEMPLOYEE
of second view in the same component.
please send me code snippet for doing the same.
Thanks in advance.
seema

Hi Seema
You can access the fields from different views by either using custom controllers or by using component controllers, in your case you can access the Sales employee BP number from the Component controller.
first access the component controller as below in BP_CONT/SalesEmployee (in do_prepare_output method) or in (specific setter method)
lv_compcontroller type ref to CL_BP_CONT_BSPWDCOMPONENT_IMPL,
lv_partner type ref to cl_crm_bol_entity,
lv_role type string,
lv_partner_no type string.
lv_employee TYPE REF TO if_bol_bo_property_access,
lv_compcontroller = me->COMP_CONTROLLER.
lv_partner ?= lv_compcontroller ->typed_context->-partner->collection_wrapper->get_current( ).
lv_role = lv_partner->get_property( iv_attr_name = 'BP_ROLE' )
IF LV_ROLE = 'SALESEMPLOYEE'
lv_partner_no ?= lv_current->get_property( iv_attr_name = 'BP_NUMBER' ).
endif.
now set the value
lv_employee ?= me->typed_context->salesemployee->collection_wrapper->get_current( )
CHECK lv_employee IS BOUND.
    lv_employee->set_property( iv_attr_name = 'SALESEMPLOYEE' iv_value = lv_partner_no )
Thanks & Regards

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>' ).

Hi,
LCSTATUS is not an attribute of the BTADMINH structure. It is read using the relation to the status object

Try reading the ACT_STATUS of object BTStatus as given below.

       data: entity type ref to cl_crm_bol_entity,
                     lv_act_status TYPE string.

Not able to set the value in marketing context node for BP_HEAD

Hi,
I am trying to set the value in marketing node of BP_HEAD from bp_addr component. i am calling the set_property method but it is not changing the value, when i debugg the code, it actually changing the value in bol structure but it is not calling the get/set method of bp head.
i am working on BP corporate person creation i.e. in bp_head component and account details view. I added the marketing attributes in UI configuration and also the address attributes.
this is what i coded in get method of country in standardaddress context node of BP_ADDR
lv_entity ?= current.
    IF lv_entity IS BOUND.
      lv_parent = lv_entity->get_parent( ).
      IF lv_parent IS BOUND.

Sorry, what I said was rubbish, because the LSMW and the session run in different external sessions.
I have searched forum for these terms: "company BUK parameter BDC background"
These threads Is it possible to set default company code in SM35? and Release BDC in SM35 in background, How to set defaul company code? seem promising, but I'm not sure they really solve.
In case these threads don't help you, I think you can create your own Z transaction which sets the BUK parameter id and then does a LEAVE TO TRANSACTION 'ABAON'. Then create again the recording on the Z transaction.
If you are using ECC6, then you may also enhance the standard to reset BUK parameter id at the very beginning of ABAON, in case it's run in batch input (sy-binpt = 'X'). Be careful as sometimes SAP does batch input on some transactions, so that could make the standard fail.
Last thing, you can contact SAP support, though it might probably be considered as consulting.

How to search data from a context node.

Hi Friends,
Thanks for ur help for previous problem . I am facing some other problem i.e how to
search data from a context node.
i have a context node :-
Car(main node) which consist of details, owners, engine and Brand as its sub node.
the value attibutes of difft nodes are:-
Car- category
Details- Mileage, Price, registration_no, miles_used
owner - name, phnno,addrs
Brand - main_brand, co_brand
Engine- Bhp,Rpm
Now i have to apply a search criteria on the basis of price, miles_used .
pls help to implement that .
Thanks & regards
Pravin jha

Hi PRAVIN,
What I can understand from your problem is that, you have a list with various properties and you want to display them and search them in your WD App. If I am correct, use the following approach:
Instead of using "details, owners, engine and Brand" Nodes, use the attributes inside the parent node. i.e in the node Car, add all the attributes viz. Mileage, Price, registration_no, miles_used, name, phnno,addr etc.
Now you can create a table of this node "Car" and can easily search on the basis of any criteria.
I hope this solves your issue. If you are looking for something else, please revert, I'll be happy to help you.
Cheers!!!

Also I cannot define the structure in the ABAP dictionary because it changes based on condition

Ok, I think I found a bug... It seems for adobe forms in WD4A, the root context node must be 1-1 and you must nest the 1-n node within that... Not sure why, but it worked. So in my case my context would look like this:
FOO_NODE (1-1)
     Widget (1-N)
          -Widget_info (1-1)
               *Name
               *Sku
               *Description
          -Widget_plant (1-M)
               *Plant_Code
               *Plant_State
               *Plant_City
          -Widget_pic (1-1)
               *Picture

Error while generating the context node

Hi ,
Requirement is to add the marketing attribute field under the Account details overview Page. As the field was not available in the context node i have added a new context node in the Account details. I used the wizard and added the context node BuilmktattributeRel so as i can add "Attribute set" under the BP overview page."
Now after adding the context node and while executing i am unable to see the overview view page, i am getting an error :
1. Component GET_ATTRIBUTE does not exist
2. Determination of BOL attributes failed
Also i am unable to regenrate the GET_I_method. If i want to delete the Zcontextnode, i am unable to do so.
Kindly help me with the technical approach to add the context node in the overview page.
Thanks in advance,
Sunil

One thread would have been sufficient.
