Abap mapping: remove a parent or child node.

Hi all,
I will trying to remove a parent node (and all childs related to it) or a specific child (field) om my XML input message to obtain a new output message.
Reading the meaning of the methods remove_node and remove child (if_ixml_node) I can not find a solution in writing the right Abap code.
My ouput document is so defined:
data: outcode type ref to if_ixml_node.
I receive the following error message when I try to find all possibilities.
Runtime Errors OBJECTS_OBJREF_NOT_ASSIGNED_NO
If someone can give me a simple code for solving my issue, I will appreciate this.
Thanks,
Regards,
Giovanni

Programmatic, using bean add Parent and child nodes in af:tree dynamically

Hi All,
i have to add parent and child nodes dynamically in tree .
Example :
i have created a tree like below.On click of button i will get value A ,from pl/sql function i will A1 and A 2 values.which i have to show in pop as tree.
A
|-----A1
|-----A2
If user clicks on A2.I have to catch A2 value and pass to pl/sql function which gives A2.01 and A2.02 values.
A
|-----A1
|-----A2
|------A2.01
|------A2.02.
A, A1 ,A2,A2.01 ...........values comes from pl/sql funchtion .
thanks in advance ......... any suggestion will greatly helps

How to differentiate parent and child node in af:treeTable ?

Greetings,
I have a requirement, I display master child view objects using <af:treeTable> component, When user expands a parent row, I have to make parent row is in read only and expanded(child) row in editable. To accomplish this I have to identify the 'node' whether it belongs to parent or child view object. In this example Tree table binds with EmpVO, There is a view link beteween EmpVO and DepartmentVO.
<af:treeTable value="#{bindings.EmpVO.treeModel}"
var="node"
rowSelection="single" id="tEqSum"
summary="Employee Summary"
<af:column sortProperty="#{bindings.EmpVO.hints.LocCity.name}"
filterable="true" sortable="true" width="90"
headerText="#{bindings.EmpVO.hints.LocCity.label}"
id="c3">
<af:outputText value="#{node.LocCity}" id="ot21"/>
expandAllEnabled="false">
</af:treeTable>
Thanks in Advance,

Hi,
You can find out the node depth by using
#{bindings.<your_tree_binding>.treeModel.depth}Based on the depth, you can decide whether its a parent node or child node (for a 1 level tree- say dept and emp, the depth for parent would be 0 and for the child it would be 1).

How to test ABAP mapping used in a Integration Process node

Hi,
anyone can suggest me how to debug an ABAP mapping used into a transformation node belonging to an Integration Process ?
Thanks.
Francesco

Hi, Francesco.
I've debugged ABAP Mapping with SXI_MAPPING_TEST transaction.
If you have creted a scenario including your ABAP Mapping, you only hace to put the correct sender/sender interface and receiver/receiver interface. You have to put some XML document as an input.
I wrote in my code the Break-point instruction an debugged the process without problems.

Find the grand parent of child node

Hi gurus,
I have a table with the following structure
Supp_Num     Parent_Num      Inidicator
     1                  Null                    0
     2                    1                      1
     3                    2                      1
     4                  Null                    0
     5                     4                     1
For all the parent Nodes the indicator will have '0'
For all the child Nodes the indicator will have '1'.
I want to write a sQL code where i provide a child name and it traces back to its root parent . For eg if i provide the procedure with Supp_Num=3 it should traverse back to 1 and give 1 as output
Thanks in advance

You wrote in your original post
I want to write a sQL code where i provide a child name and it traces back to its root parent . For eg if i provide the procedure with Supp_Num=3 it should traverse back to 1 and give 1 as output
And my solution did exactly the same. Now if you want the Root details for SUPP_NUM=5, it will provide the root node for same. See below:
with data as
select 1 supp_num, null par_num, 0 ind from dual union all
select 2 supp_num, 1 par_num, 1 ind from dual union all
select 3 supp_num, 2 par_num, 1 ind from dual union all
select 4 supp_num, null par_num, 0 ind from dual union all
select 5 supp_num, 4 par_num, 1 ind from dual
select *
from (
        select supp_num, par_num, ind
          from data
         start with supp_num = 5
        connect by supp_num = prior par_num
where par_num is null;
SUPP_NUM               PAR_NUM                IND
4                                             0
You just need to set the START WITH clause with appropriate SUPP_NUM.

Problem while handling Parent and child nodes in CE

Hi all
I am facing a problem with handling Child and Parent nodes in CE.
I have a Table in which I have drop downs. On selecting a value in the drop down, I have to take that value and do some action.
I am trying to access the value in the following ways
wdContext.nodeParent().currentParentElement().nodeChild().currentChildElement().getVaActivity();
wdContext.nodeChild ().currentChildElement().getVaActivity();
When I select the drop down from the first row of the Table the code works fine.
But when I select other rows, it returns the current value of the first row.
The lead selection of the parent always returns u20180u2019 even though you have done some action in row 2,3 etc.
The same code gives the required values in EP 7.0; I.e.: it returns the values form selected row in the table.
Basic problem is that the current value of parent always returns the first row.
Following are the Properties of the nodes
Parent
Collection Cardinality: 0-n
Singletone: true
Child:
Collection Cardinality: 0-n
Singletone: false
Please help
Regards
Deepu

Hi,
 In CE changing dropdown selections doesn't fire table leadselection events. If you want to use a dropdown in a context-driven UI element like a Table, you need to use of event parameter mappings. So here are the steps:
1. Create a new action for the onSelect event of the dropdown (I will write the code for DropDownByIndex), let's call it Select.
2. Add a parameter parentElement whose type is same as the type of the parent node element. So from your example it would be IParentElement. Select the chek-box for "Adapt event-handler parameter". This will add a new parameter to the event-handler method onActionSelect called parentElement.
3. Write this inside wdDoModifyView :
if (firstTime) {
 IWDAbstractDropDownByIndex ddi = (IWDAbstractDropDownByIndex) view.getElement("<id of DropDownByIndex>");
 ddi.mappingOfOnSelect().addSourceMapping(IWDAbstractDropDownByIndex.IWDOnSelect.NODE_ELEMENT,"parentElement");
3. If you want to set the lead selection of the table to the row where the dropdown is write this inside the event-handler:
wdContext.nodeParent().setLeadSelection(parentElement.index()); //parentElement is the event handler parameter added through the action.
Note that the event parameter IWDOnSelect.NODE_ELEMENT points to the node element that defines the data mapping for the containing row and not the node element of the source for the dropdown. This has been specfically added for such a scenario. All this is well documented [here|http://help.sap.com/javadocs/nwce/current/wdr/com/sap/tc/webdynpro/clientserver/uielib/standard/api/IWDAbstractDropDownByIndex.IWDOnSelect.html#NODE_ELEMENT].

Hi,
you need to provide the full naming for the facet names. So instead of DepartmentsView you provide mypackage.DepartmentsView where you replace mypackage with the package structure of the the ViewObject

Moving child node's parent in JTree

hi guys.
What i have is a Jtree dynamically generated, im trying to re-arrange the nodes inside.
each nodes and their parents have their own values and been built with DefaultMutableTreeNode.
So im thinking, to do so i first need to analyse which child node i want to move, then remove it from its current parent, then set the new parent to this node.
I been thinking of using the values and compare them to do the parent-node matching, however, i have been looking at the APIs without luck, for methods to possible retrieve the values of the childs/parents.
Or perhaps there is a simpler way,
Does anybody have a clue where i could find some answers to this problem?
Cheers, Eric.

Cheers, Eric.Not sure what the problem is exactly. DefaultMutableTreeNode has methods for retrieving it's parent and child nodes: which is all you need to move nodes in your tree.

How to identify the current lead selection is child or parent in rec node

Hi
I am using a recursive node to populate a table with TreeByNestingTableColumn as master column. Now my problem is how do I identify if the current selected row in the table is a child or parent? When I get the lead selection value, I find that its the same for the parent and the child. I am setting the isLeaf and hasChildren boolean properties appropriately as false and true for parent and true and false for child. But since the lead selection is returning the same the below rsTableElement always gives me the parent, I always get those parameter values as that of parent. I am writing this inside the onleadSelect event of the table.
IRsTableElement rsTableElement = (IRsTableElement) wdContext.nodeRsTable().getElementAt(wdContext.nodeRsTable().getLeadSelection());
In this scenario how do I know if the current selection is made on a child?
Appreciate for all help and any code snippets.
Thanks,
KN.

Hi KN,
I guess you want to check if the node that you selected is parent or child.. This can be achieved by using getTreeSelection() method of IWDNode.
If you write following code in your lead selection action, you can determine the if it is a parent or child node.
wdComponentAPI.getMessageManager().reportSuccess(wdContext.nodeRsTable().getTreeSelection() +"");
the output will be something like
<ViewName>.RsTable.0.ChildRsTable.1.ChildRsTable.0.. depending upon which node you have selected.
That way you can find out if it is a parent or child node.

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

Abap mapping - get_value from child node

Hi experts,
I'm doing an abap mapping, but i have some problems extracting data from XML message.
I have:
child = element->get_first_child( ).
while not child is initial.
       wa_reg-registro = child->get_value( ).
       insert ZTABLE from wa_reg.
      child = child->get_next( ).
endwhile
I can see in my table ZTABLE the expected result, but consecutive blanks are all replaced by exactly one space character .
Why?
How can I solve this problem?
Thanks

IDOC mapping issue (calculation using parent and child fields)

We are mapping an IDOC to a file for output to a third party. The IDOC has many segments, some of which are embedded. This is where I'm having the issue. I am trying to perform a calculation on a field from the parent node (E1EDP01-MENGE) with the field from the child node (E1EDP05-KRATE) to determine the total tax for that line (qty X rate).
Issue: The mapping that is in place is using the same MENGE value for all calculations, even where the E1EDP01 segment is not a parent of the E1EDP05 segment.
Please review the screen prints and explain how I can correctly group the E1EDP05 child segments rate field (KRATE) with the corresponding parent segment E1EDP01 quantity (MENGE).
Example:
Parent segment, E1EDP01 / Child segment E1EDP05 (There are many E1EDP05 segments for 1 E1EDP01 segment)
E1EDP01 (parent node)
E1EDP05 (child node)
Target structure
ITEM (parent) --->E1EDP01 is mapped at node level
-->ITEM_DATA --->E1EDP01 is mapped at node level
-->ITEM_TAX --->E1EDP01 is mapped at node level
 -->(fields for item_tax)
 -->Record type
 -->Invoice number
 -->Line total
 -->etc...
I am mapping (E1EDP01-MENGE) for calculation with (E1EDP05-KRATE) to determine tax at the line item level. I have the context set at each Node, E1EDP01 for MENGE and E1EDP05 for KRATE. I was using CopyValue, but this was using the frist occurence of MENGE for all line items.
mapping example
*I am using MENGE (Copy_Value) then multiplying by KRATE to get the line item total. This was causing the same MENGE (because of Copy_Value) for all line items.
E1EDP01-MENGE|Copy_Value|MULT--->TAX_ITEM-LINE_TOTAL
E1EDP05-KRATE|
I removed the CopyValue and now I'm getting the following error:
Cannot produce target element /ns0:MT_DTN_INVOICE1/INVOICE/ITEM/ITEM_TAX[3]/LINE_TOTAL. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd
How can I map this so the child records (E1EDP05) are grouped with the correct parent records (E1EDP01)?
Thanks in advance!

Problem with childs nodes and automatic key mapping in a Data Object

Hi experts!
I'm doing the service order tutorial from the mobile help at [this link|http://help.sap.com/saphelp_nwmobile71/helpdata/en/21/9b5b924c3b434fba4767731794b029/frameset.htm] and I have a problem...
In the topic "Modeling the Equipment Data Object", says you have to mark the "Automatic Key Mapping" checkbox. So when I had to create a third child node ( the location node ) the system raised an exception with the message "Deselect automatic key mapping flag for more than two-level nodes". I'm trying deselecting the flag and creating the location node, but when I want mark again the automatic key mapping flag, this is disabled.
What can I do to solve this and create the three child nodes with the flag marked? It's a configuration thing?
Any help it's very welcome. Thanks in advance.
Best regards,
Simon.

The thing is: Its not allowed to use automatic keymapping if you have more than two levels. This is why the message showed up, and this is why its been disabled.
What automatic keymapping does: Figures out automatically which child node belongs to which parent (by guessing from the field name and type, which fields in the child correspond to which key fields of the parent).
On three levels, this becomes more complicated => Its disabled.
How to do keymapping yourself instead of having the DOE do it automatically: Do 'Explicit keymapping' from each child to its parent. Explicit keymapping is done by clicking on the corresponding menu button in the child node. Here you need to associate child node fields (they need not be key fields of the child, but they are allowed to be that as well) to each of its parent nodes key fields (so that each child can be associated to its parent).
Cheers
