Mapping - Remove Node

Hi,
I need to implement the following scenario:
I have one source message type with this structure:
<Products>
   <Product>
      <product_code>Code01</product_code>
      <product_description></product_description>
   </Product>
   <Product>
      <product_code>Code02</product_code>
      <product_description>Product 02</product_description>
   </Product>
</Products>
The desired target message should be like this:
<Products>
   <Product>
      <product_code>Code02</product_code>
      <product_description>Product 02</product_description>
   </Product>
</Products>
If product_description is empty or doesn't exists in source target then that product should not be generated in target message.
How can i achieve this is message mapping?
Thanks,
Pedro Leal

Hi Pedro,
To achieve your requirment, you will have to use the node function exists and creatIf. Provide the condition like:
product_discription-> exists --> createIf -> Product.
The rest is 1...1 mapping.
Thanks and Regards,
Sanjeev.
PS: Award points if helpful.

External Context Mapping and "The Mapping to Node...Has Not Been Completed"

Hi there,
I've got 2 components: A, B where A consumes the data provided by B.
I'm calling the component B which includes a view provided by A. This view (provided by A) needs data inputted by the user in a view in B.
The context of B contains a node called MULTIVALUES flagged as Interface + Input Element Ext.
The component A uses the component B, in the component usage interface controller of the component A I've referenced the component controller of A. I have then created a node in A's component controller and done the mapping from the component usage interface controller of A to A's component controller.
The manually created component controller node in A is NOT an interface.
Now when I invoke B I'm getting an error:
The Mapping to Node COMPONENTCONTROLLER.1.MULTIVALUES Has Not Been Completed.
What's still missing?
Thank you!

it is indeed much more complex and you need lot of understanding about the component instances and their life time.
What i do normally for such complex cyclic dependency , i try to split the common part which is needed in bot component_a and component_b and create a new super component_s.
Component_s is used in both components. You can even go further that you create view component which has nothing but the viewContainer UI elements to embed the views from component_a and Component_b.
The view component has to create all the used components (comp_s,comp_a,comp_b) and after creating call the interface method in comp_a and comp_b to set the component usage of comp_s (use the if_wd_comp_usage=>entering-referencemode).
In this way the comp_a,comp_b share the same instance of comp_s.
What i am saying is to look for a solution in application architecture and not with in the exiting components coding.

The Mapping to Node &ATTRIBUTE_NAME& Has Not Been Completed.

Hi All,
Could anybody tell me when this exception arises.
we could not track this exception as all the mappings have been done as desired.
Need help immediately.
Regards,
ARti.

Hi Aarti,
I encountered the same problem, but could resolve it.
There are two kinds of context mapping possible:
1)Cross component context mapping - In this case, the properties of the interface context node of the used component would look like:
Interface Node: X
Input Element (Ext.): must not be set
Then in the COMPONENT CONTROLLER of the using component, map the desired context node on the left hand side (of the component controller) to the interface node of the used component on the right hand side.
This is done when we need to receive value of the interface context node of the used component in the using component.
2)External context mapping: In this case, properties of the interface context node of the used component would look like:
Interface Node: X
Input Element (Ext.): X
Next in the CONTROLLER USAGE in the using component(this is a new node added in the hierarchy in SE80 when displaying the WD component, when component usage has been declared in the current component), right click the desired component usage and select 'Create controller usage'. Now it is here where you define mapping between the interface context node and the context node of the current component controller. By doing this, component controller of the using component would act as the data source.
This is done when we need to pass value to the used component from the using component.
The important point to remember is that whenever attribute Input Element (Ext.) of the interface node has been marked as X, ensure to define a mapping for this context, else it results in a runtime error "The Mapping to Node COMPONENTCONTROLLER.1.<interface_context_node> Has Not Been Completed" .

The error is " The Mapping to Node has not been completed

Hi All,
I am getting a strange type of error and need help immediately.
The error is " The Mapping to Node COMPONENTCONTROLLER.1.PLANNING_ENTITY Has Not Been Completed" for the node that exists in the Parent component and is being used in all the child nodes thru reverse mapping.
I have done mapping in all the child nodes but still the message is coming.
Could anybody tell me the reason .
Regards,
Arti.

Basically somewhere you have defined a context node 'PLANNING_ENTITY' to be an Input-Element. At the same time you did not define (through a component usage at design time) where the input to that node is coming from. This means the mapping path to the node is not complete, and the node does not know where it is mapped to.
Either:
- You untick the checkbox 'Input-Element (ext.)' inside the controller context, or
- You find the component that uses the component with the node 'PLANNING_ENTITY' and select Component_Usage->'Name of Usage'->'Add controller usage'. Inside the controller menu you see then, you can now provide a mapping to the context node.
I realise this now sounds a little confusing, but I'm happy to provide more details should you need them.
Cheers,
Robin

Mapping one node to many nodes

How do you map one node in a controller context to many other nodes in another controller context?
Here's the situation I'd be using this.
I have an Adaptive RFC model from which I created a Custom Controller. I then used the wizard to map to the model.
The model corresponds to RFC functions and many of those functions accept the same parameters, LanID for instance. I simply want to have one "LanID" node in a controller that I would set. The change would then propagate to the other LanID context nodes in the Custom Controller mapped to the model.
What's the best way to handle this?

If I understand correctly.. B1, B2 and B3 are all in the SAME custom controller? Even if they are, I don't see a problem of mapping them all to A1 which is in another controller. Let's say that A1 is the "original" node, and B1, B2 and B3 are the "mapped" nodes.
If you require that B1, B2 and B3 are "original" nodes, and A1 is the "mapped" node, then this is scenario is impossible.
If you can be more specific, I will try to answer your question better.

Context Mapping: child-nodes of non-mapped parent nodes

I am somewhat curious about Context Mapping in WebDynpro.
Which parents nodes need to be mapped in order to map child nodes ? Does a child node has more than one parent node (e.g. grandparent - two steps above) ?
A.1 -
MAPPED----
>    B.1
- A1.1   NOT MAPPED
- A1.2   NOT MAPPED
        - A.1.2.1     MAPPED TO>    B.1.2.4
        - A.1.2.2   NOT MAPPED
- A1.3   NOT MAPPED
Is it sufficient that only one of these parent nodes (e.g. direct parent node not mapped, but parent node of this parent node is mapped) need to be mapped so that the child node can be mapped ?
Is this assumption true or not ?
The SAP library states:
"Conversely, child nodes of non-mapped parent nodes cannot be mapped, otherwise this would result in irresolvable conflicts at runtime with respect to the parent-child relation in the context and the mapping relation." (http://help.sap.com/saphelp_nw04/helpdata/de/51/a3384162316532e10000000a1550b0/content.htm)
This statement is not absolutely clear on this issue.

Let me put it this way
You have a node vehicle and you have a child node for that the car. The car node have parameters car1, car2.
Let the vehicle node have parameters veh1 and veh2
Then if you map vehicle node one to any other node (say in the comp. controller) you have the option of mapping its children i.e veh1,veh2 and carnode.
You can have that veh1 is mapped and veh2 is not mapped.
vehicle node(mapped)
veh1(may or may not be mapped)
veh2(may or may not be mapped)
car node(may or may not be mapped)
If instead you try to map only the car node the vehicle node will also get mapped automatically but not it's child parameters like veh1 and veh2.
vehicle node(mapped)
veh1(may or may not be mapped)
veh2(may or may not be mapped)
car nodemapped)
car1(may or may not be mapped)
car2(may or may not be mapped)
Hope this would help.
Do revert for further clarification

Map context node web dynpro to context DATA of interface controller ALV

Hi Experts,
I have started creating simple ALV by following the example in the below mentioned link.
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/3439404a-0801-0010-dda5-8c14514d690d
I have completed 95% development but stuck with last bit of
Set data to ALV for display (via reverse context mapping).
When Click on the Controller Usage button. The component controller of your Web Dynpro component DOES NOT appears on the right side of the screen.
Therefore I can not Map context node NODE_FLIGHTTAB of your Web Dynpro component to context DATA of the interface controller of the ALV component.
Could you please shed me light on this.
Your time and help much appreciated.
Best Regards
CB

Hi Chandra,
You need to add component controller first. Just go to the property tab of interface controller of the alv component and click on create button and then add the component controller. After that you'll be able to see the node in the context tab.

Dynamiclly remove node from JTree

hi all,
I want to remove nodes from a tree dynamically. I used "treeModel.removeNodeFromParent(node);". The node was removed from that treeModel, but the tree never updated. I tried to use tree.repaint() method. It doesn't work. Any suggestion?
thanks a lot in advance.

try with TreeModel.reload(); This will surely work

Remove node using Grid Control

Hi
Can you post some steps removing node from 10gR2 CRS using Grid Control
Have 4 node cluster, and wants to impliment steps this way.
1) First remove instance(s) on node to remove by going "CLUSTER DATABASE(S)"
select SERVER
under "Change Database" select "delete instance" go from there...
2) go CRS page and choose "Monitoring Configuration" and choose and update
I have manual steps.. but wants to try with GC...
Any information is helpful
Thanks,
Krishna.

I have never gotten Grid Control and database control working for a single database. I have tried. Oracle dbca gives you a choice for Grid Control or database control but not both.
Right, because intuitively it doesn't make much sense (but, as i mentioned, my situation is a bit out of the norm).
But, would there be some sort of error message returned if you did go in and manually start EM? Have you tried to go in and manually start up the dbconsole when GRID control was already running?
I checked the port.ini file and it showed this:
Enterprise Manager Console HTTP Port (SAIN) = 5500
Enterprise Manager Agent Port (SAIN) = 1831
So it's recognized in that file. It seems odd that DBCA would bother to include that if you select instead Grid Control.
Regarding the additional overhead of running both, would it be a big deal to simply turn EM on when I want to use it, then to turn it off so as to eliminate the additional overhead??

How to map the node which i have created dynamically into the view

Hi All,
Many thanks to all ur answers in advance.
I have created a node dynamically.I want to display the fields which i have fetched in that node.
i dont know how to map the node which i have created dynamically into the layout of the view.
Other than Using ALV is there any other way to do.
for example usin table control

Hi,
use the reference variable of view to access the corresponding UI element and then use the method of that UI element to do data binding with context node.
for ex:
Context node = flights
element = inputfield, ID = inp_name
data view type ref to if_wd_view.
data lr_inp type ref to cl_wd_input_field.
lr_inp ?= view->get_child_element( ' INP_NAME' ).
use following methods of input field to define the data binding.
SET__DDIC_BINDING( )
BOUND__PROPERTY( ).
BOUND__PRIMARY_PROPERTY( ). " for input field it is value property.
Get the reference of view from wddomodifyview method as importing parameter(view). Store this parameter as controller attribute.
Thanks,
Rahul

How to remove nodes in Message mapping

i want to remove in resultanat xml file..
please tell me how to remove if the values are not exsisted for that Segment ..
i think its possible in message mapping..
please guide me..
Munna

Hi Munna,
Try Creating a UDF in your mapping name it like: "Create"
Paste the below mentioned code in it
========================
String str = a;
if(str != null && str.length()>0)
return "true";
else
return "false";
========================
2) Save this function .
3) Now Map like this
(Source Node->UDF Create)->Check if it returns a string "true"--> if yes Map it with source node->add this in the "then" of an "if with out else"---->Target node.
4) Test now in testing tool in Message mapping.
Try it.
it will work

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....
