How to change Context Node/Subnode parameters?

How can I change node parameters AFTER I have created them? For instance, I have a sub-node of a lead node. I now want to assign a supply method to the subnode however, I can not edit this now. Is this possible? Thanks!

Never mind....found it....I have to change it at the COMPONENT CONTROLLER context level...NOT at the VIEW context level. Doh!

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' ).
LR_ENT ?= LR_COL->GET_FIRST( ).
IF LR_ENT IS BOUND.
    LR_ENT->GET_PROPERTY_AS_VALUE( EXPORTING IV_ATTR_NAME = 'DIVISION' IMPORTING EV_RESULT = LV_DIVISION ).
ENDIF.
I'll appreciate if you can provide me some documents to refer.
awaiting for your responses.

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.

How to get Context Node data in respective HTM page

Hello Experts,
My Scenario is as follws: Two views are there one is table view[contain customer data] and another form view[where i require the data]. my requirement is, table view is having customer information with their city names. i need the city name in my form view's .htm
Both views are having same context node which are bounded via custom controller.
Could you help me out to solve this
With Regards
SRiNi

Hi,
this should be very simple as the context nodes are defined as page attributes on your .htm page.
Example:
Your Context node is named /TEST/.
In your .htm page you can access it by:
<%
data:
lr_property type ref to if_bol_bo_property_access.
lr_property = /test/->collection_wrapper->get_current( ).
%>
EDIT:
In case there is no page attribute, you can use the SET_MODELS method in the view implementation class to set a variable. Be sure to create the variable you want to set on the .htm page in the page attributes first.
cheers Carsten

How to populate context node of component controller

Dear People,
Is there any way i could access my custom context node of component controller in the context node class of my custom controller.
I am navigating from one component to another, Upon initial launch everything is working fine, however if i go to home page and come back. the assignment block is coming empty.
In WD_USAGE_INITIALIZE i m binding my custom controllers context node with the component controller's context node of the other component and it works fine when i load the UI. however if i go to home page and come back. the assignment block is coming empty.
Following code is in method of DO_VIEW_INIT_ON_ACTIVATION of the other componenet.
METHOD do_view_init_on_activation.
DATA:   lv_btstatus_parent TYPE REF TO cl_crm_bol_entity,
        lv_comp_ctrl      TYPE REF TO cl_btstatus_bspwdcomponen_impl.
CONSTANTS:
        lc_us_header      TYPE crmt_relation_name VALUE 'BTStatusHUserAll',
        lc_us_item        TYPE crmt_relation_name VALUE 'BTStatusIUserAll'.
lv_comp_ctrl ?= me->comp_controller.
check if relationname has been passed from outside
    gc_relation_name = lv_comp_ctrl->get_relation_name( ).
IF gc_relation_name IS INITIAL.
check type of parent to determine relationname
    *lv_btstatus_parent ?= lv_comp_ctrl->typed_context->btstatusparent->collection_wrapper->get_current( ).*
   check lv_btstatus_parent is bound.
    CASE lv_btstatus_parent->get_name( ).
        WHEN 'BTStatusH'.
          gc_relation_name = lc_us_header.
        WHEN 'BTStatusI'.
          gc_relation_name = lc_us_item.
    ENDCASE.
ENDIF.
CALL METHOD super->do_view_init_on_activation.
ENDMETHOD.
Here lv_btstatus_parent is bound during initial launch, however after navigating back to the same page, its blank leading to exception.
any suggestions would be helpful.

Change SIA node name after restaure

hi,
we have backup an XI31 system (on server named AAA) and restaure it on another windows server ( named BBB).
on CCM the SIA name is SIA.AAA
on CMC the node for each server XI is AAA
the pid for each server is AAA.server.pid
how to change this node name ?
recreate SIA ?
thank's

Hi
you have two options:
1) In the CCM create a new SIA with the default servers (use other CMS and SIA ports than the defaults) and point the CMS to the old repository. hen finished just remove the old SIA. Drawback: you have to reconfigure your server settings.
2) Try to clone the old servers in the CMC (I assume you already have a CMS running on the new node) and when you through activate the new servers and remove the old ones. Do not forget to deactivate the old SIA in the CCM.

Changing Certain Node Icons

I can't seem to figure out how to change certain node icons in a JTree due to a 3 letter string. For example 2 nodes one saying "Intro" the other say "Edit - SEC" - the one with SEC has a different icon to "Intro"
MyRenderer class, here the code which is used to check the string of the node......
if(leaf && isSecuredFile(value)) {
setLeafIcon(leafSecuredIcon);
setToolTipText("This file is Secured Access Only");
else {
setToolTipText(null);
return this;
protected boolean isSecuredFile(Object value) {
DefaultMutableTreeNode node = (DefaultMutableTreeNode)value;
NodeRecord nodeInfo = (NodeRecord)(node.getUserObject());
String nodeTitle = nodeInfo.NodeRecord;
if(nodeTitle.indexOf("SEC") >= 0) {
return true;
return false;
}// MyRenderer class
I tried the above piece of code, and it compiles with no errors but when I try to run the applet it comes up not initialised with the following....
java.lang.NoClassDefFoundError: MyRenderer
at firstPanel.<init>(firstPanel.java:99)
at JNavigator.jInit(JNavigator.java:55)
at JNavigator.init(JNavigator.java:40)
at sun.applet.AppletPanel.run(AppletPanel.java:344)
at java.lang.Thread.run(Thread.java:484)
However if I take out this code it works fine but I need to be able to assign different icons depending on the node title string. Therefore I need help.

here's the whole class, if thats any help...
public class MyRenderer extends DefaultTreeCellRenderer {
ImageIcon leafIcon;
ImageIcon leafSecuredIcon;
public MyRenderer() {
leafIcon = new ImageIcon("Leaf.gif");
leafSecuredIcon = new ImageIcon("LeafSecured.gif");
public Component getTreeCellRendererComponent(JTree tree, Object val, boolean sel, boolean expand, boolean leaf, int row, boolean hasFocus) {
super.getTreeCellRendererComponent(tree, val, sel, expand, leaf, row, hasFocus);
// sets Icons
setLeafIcon(leafIcon);
setClosedIcon(new ImageIcon("Folder95C.gif"));
setOpenIcon(new ImageIcon("Folder95O.gif"));
// set Expansion icons to + -
ComponentUI treeUI = tree.getUI();
if(treeUI instanceof BasicTreeUI) {
((BasicTreeUI)treeUI).setExpandedIcon(new ImageIcon("minus.gif"));
((BasicTreeUI)treeUI).setCollapsedIcon(new ImageIcon("plus.gif"));
// decides who icon to use
if(leaf && isSecuredFile(value)) {
setLeafIcon(leafSecuredIcon);
setToolTipText("This file is Secured Access Only");
else {
setToolTipText(null);
return this;
protected boolean isSecuredFile(Object value) {
DefaultMutableTreeNode node = (DefaultMutableTreeNode)value;

String nodeTitle = nodeInfo.NodeRecord;
if(nodeTitle.indexOf("DOM") >= 0) {
return true;
return false;

How to find if a particular context node attribute is changed.

Hi,
When a screen is opened, the context node attribs has some values. On some event, i wanted to check if one particular attribute in the context node has changed. Is it possible to figure this out.
(ps note that I need not find if any change has happened to the entire table but only one column (attribute) of the node. Note that the node has cardinality 0...n. So there are multiple possible values)
Thanks in advance.
regards,
suresh.

Hi,
If you use the [Context change log|http://help.sap.com/saphelp_nw2004s/helpdata/en/ae/f95e42ff93c153e10000000a1550b0/frameset.htm]
and loop over the result table, looking for a certain attribute name and node name,
you'll get all the changes of that attribute, for all elements in that node.

Sort a context node that has subnodes

I have a context node with cardinatliy 0:1.
It has one subnode, 3 attributes, and a recursive node.
Now, I would like to sort the content of the node by one the three attributes.
How can I do that?

Hi Daniel,
but if the subnode is mapped on the parent, it will have the same 0...1 cardinality - and it won't make sense to sort it.
If perhaps both the parent and subnode have 0...n cardinality but you are only creating one root element - this makes more sense.
Sorting the second/third/nnn level of a hierarchy is difficult - because it is difficult for the user to specify which level they want to sort. I would assume that you'd just make it so that ALL levels were sorted according to whichever criteria you choose.
You could consider representing your data as a table popin's (which would then make it more obvious which level was being sorted) but if your data has n levels of hierarchy this will very quickly become a nightmare of recursive dynamic coding.
As you are no doubt aware, the standard table sorting logic as implemented in CL_WDR_TABLE_METHOD_HNDL does not work for hierarchical tables. (7.01, goodness knows, it might in 7.02)
So I see two options:
I think you would either have to go down the path of creating your own table handler, unfortunately the standard table handler CL_WDR_TABLE_METHOD_HNDL is marked as final - so you couldn't just subclass that and override the sort handling (which doesn't work for hierarchical tables). Instead you'd probably have to re-implement. Then reassign the handler in the WDDOMODIFYVIEW. I remember doing similar sorts of things to implement sorting in WDJ in the early days when the standard handler didn't do all I needed it to do. (i.e. it was sorting by key rather than by text for dropdown by keys).
Or, in the event when you open/display a node, sort the contents according to the state of toggle buttons that you implement in the root node of your hierarchy. When these toggle buttons change state - recursively sort your your entire context.
This means you don't have to mess with the standard table handler, but does give a very non-standard sort implementation.
Good luck, if you have any questions, please do let us know.
