Workflow '399538': No successor exists node 27 with value '8994'

Hai All,
I created a Workflow with 2 steps... (1 Activity for Approve/Reject and Second Activity - Send corresponding Mail)
When Executing first step, a mail has to be sent to the WorkflowInitiator...stating the status (whether approved or Rejected) and I am facing a problem in this phase.
When executing Step-1, the mail is not Sent and when I take the Log... it shows the error... Workflow '399538': No successor exists node 27 with value '8994' ...
What could be the reason??? I would appreciate your suggestions...
Thanks & Regards.

Hi All,
I am having the similar problem. This was a workflow developed in 4.7 and upgraded to ERP2005 and this is a Personnel Requisition workflow. Client developed a custom WD application for approval process and when the agent processes the form and approve/reject, am updating the workflow container(SAP_WAPI_WRITE_CONTAINER) to approved which is one of the outcome of the task and also return parameter from task to workflow container. After updating the container i am completing the workitem manually with the function SAP_WAPI_WORKITEM_COMPLETE. But thr workflow is not going forward instead i am seeing the error "Error when defining the successor for node &1".
When i looked at the template the node numbers are not in sequence, is this a cause of the issue???
Any help is appriciated.
Thanks and Regards,
Sunil

How to populate value node with values?

Hi Experts,
I have created a new view with a vlaue node of table type.
How can I populate values into the value node?
Which method will be useful?
Is there any material for Web UI Programing?
Please help me in this.
Thanks,
Adi.

Hi Adi
If ZVal is your value node then,
DATA: lref_entity    TYPE REF TO cl_bsp_wd_value_node,
        lref_bo_coll   TYPE REF TO if_bol_bo_col,
        lref_data TYPE REF TO <<your ZStructure>>,
         ls_data type <<your ZStructure>>.
ls_data-<<field1>> = 'XYZ'
ls_data-<<field2>> = 'XYZ'
     CREATE OBJECT lref_bo_coll TYPE cl_crm_bol_bo_col.
      CREATE DATA lref_data.
      CREATE OBJECT lref_entity
        EXPORTING
          iv_data_ref = lref_data.
      lref_entity->set_properties( ls_data ).
      lref_bo_coll->add( lref_entity ).
      typed_context->ZVal->set_collection( lref_bo_coll ).
Hope this was helpful.

Map Drop down to Context node with value and ID

I want to map a drop down to dynamic data. I have a table that is populated at runtime after a BAPI call. The structure is the same as if you used a simple type. i.e. Value and ID.

Hi Gordon,
Try out this
ISimpleTypeModifiable myType=wdThis.wdGetAPI().getContext().getModifiableTypeOf("MonthName");
//Set allowed values for this data type
IModifiableSimpleValueSet values=myType.getSVServices().getModifiableSimpleValueSet();
values.put("0","January");
values.put("1","February");
values.put("2","March");
values.put("3","April");
values.put("4","May");
values.put("5","June");
values.put("6","July");
values.put("7","August");
values.put("8","September");
values.put("9","October");
values.put("10","November");
values.put("11","December");
where MonthName is a value attribute of type string.

How to search for a text node with a particular value in an xml document with labview

supposing i have the following xml document:

<book>
<bookname>the spear warrior</bookname>
<author>britney</author>

<book>
<bookname>the beard</bookname>
<author>derrick</author>
</book>
</head>
i want to search for the author of the book "the beard" using for example the V.I Get first match of labview to access the the node with value "the beard" and then use Get next sibling V.I and Get node text content to get get the author of this book..so my question is how do i write the xpath expression for Get first match so as to access the node with bookname "the beard" instantyly? am trying to minimise the use of loops because they increase the time duration,..thank you (NB:i dont want to use Get all Matched V.I because it obliges me to use a loop in order to access the name derrick and this increases the time duration for my v.i)

Since it's all text, why not use a real quick Match Pattern (or Regular Expression, but you don't need that much power here), see attached.

Create xml file with values from context

Hi experts!
I am trying to implement a WD application that will have some input fields, the value of those input fields will be used to create an xml file with a certain format and then sent to a certain application.
Apart from this i want to read an xml file back from the application and then fill some other context nodes with values from the xml file.
Is there any standard used code to do this??
If not how can i do this???
Thanx in advance!!!
P.S. Points will be rewarded to all usefull answers.

Hi,
you need to create three util class for that:-
XMLHandler
XMLParser
XMLBuilder
for example in my XML two tag item will be there e.g. Title and Organizer,and from ur WebDynpro view you need to pass value for the XML tag.
And u need to call buildXML()function of builder class to generate XML, in that i have passed bean object to get the values of tags. you need to set the value in bean from the view ui context.

Error when defining successor of node in workflows

Hi Experts,
I am receiving an error which says "error when defining successor of node XYZ". However in my workflow template, this particular XYZ node does not exists.
Also I found one entry in SWP_SUSPEN table for the main workflow. I tried to execute the report manually RSWWERRE. Still it did not work out.
I also tried to use transaction SWF_ADM_SUSPEND. However my workitem is not showing in the list.
Kindly help me in this issue.
Thanks
Gopal

Hi,
This problem occurs because the nodes system table with respect to workflow is not updated properly. I hope you might have deleted or changed the workflow design after this you need to update the index of the workflow template too.
Follow the below steps
1. Execute PFTC choose task type as Workflow template and open in change mode.
2. On menu goto Addtional Data ---> Agent Assignment ---> Maintain
3. Choose the workflow template ID and click on the icon on the application tool bar with Red and white colur (Football ) i am not sure I think you can try with CTRL + F11 but you hvae to update the index.
After doing this Execute SWUD txn Check for the consistencies of the workflow template. if you do not find any error refresh the buffer and org environment.
Even after doing all this stuff you still face the issue then generate a version just simply insert a dummy step in the workflow activate and then delete the dummy step activate and refresh the buffer and org environment and try to execute.
This error ususally occurs (upto my knowledge) if the nodes table of the workflow is not updated properly, So the above mentioned ways are to deal with it.

Using XSLT to extract value of a XML node with namespace

I have a XML source code here.
<?xml version="1.0" encoding="utf-8" ?>
<rss version="2.0" xmlns:job="http://www.pageuppeople.com">
<channel>
    <title>SMH Jobs</title>

      <job:location PUReferenceID="3711">Sydney - Inner Suburbs & CBD</job:location>
    </item>
</channel>
</rss>
I want to use XSLT to extract value of a XML node with namespace <job:location>, and the returned value should be string 'Sydney - Inner Suburbs & CBD'. I tried a few XSL code below, but failed with error or nothing was returned.
<xsl:value-of select="job:location" disable-output-escaping="yes"/>
<xsl:value-of select="job/location" disable-output-escaping="yes"/>
<xsl:value-of select="job\location" disable-output-escaping="yes"/>
<xsl:value-of select="location" disable-output-escaping="yes"/>
This might be an easy question for you, but I would appreciate if anyone can help.

Hi Suncorp IT Learner,
We need to tell the XSLT that some elements are in another namespace. Copy the xmls declarations for the prefixes you need to use. Then use the xsl format as:
<xsl: value-of select=”job:location/@PUReferenceID”/>
In following issue, Chriztian has a good explanation:

Value nodes with depth in Context - programmatically binding.

I am resonably new to Java Webdynpro and have been unable to solve this issue so far if someone has a link to a implementation (pseudo code) it would be greatly appreciated.
I have a context supplied from an interface that is not flat.
With data in the context it may look something like this with value attributes in each Node
Context -
-Node A1
           --- Node B1
           --- Node B2
- Node A2
           --- Node B3
           --- Node B4
If the A nodes where only nodes I could loop through the number of Nodes I wanted to create, something like;
   INodeAElement tempNode = wdContext.createNodeAElement();
   tempNode.setAttributes ..........
   wdContext.NodeNodeA.bind(tempNode).
or build and arraylist and bind that ...but when it comes to a Node with daughter Nodes I havent the slight idea of how to build the structure. I'm sure its a very simple answer but I have no idea how to do it, and I havent been able to find any reference on how to do it.
Can anyone point me in the right direction ..
thanks in advance.

Context -
-Node A1
--- Node B1
--- Node B2
- Node A2
--- Node B3
--- Node B4
It depends on if the B-nodes are singleton or non-singleton child nodes.
For non-singleton child nodes there exists one B-node for each A-node-element.
In that case the context can be filled like this:
IA1Element a1 = wdContext.nodeA1().createAndAddA1Element();
for (int i = 0; i < some_number; ++i)
IB1Element b1 = a1.nodeB1().createAndAddB1Element();
for (int i = 0; i < some_number; ++i)
IB2Element b2 = a1.nodeB2().createAndAddB2Element();
And so on.

HI Can I add a child node to an Element Node with a name that exists

HI,
Can I add a child node to an Element Node with a name that is already existing in the Element Node.
Let me explain what I need exactly.
My Existing element Node looks like this:
<form>
<name>
<FirstName></FirstName>
<LastName></LastName>
</name>
</form>
Can I add another child node with hte name 'FirstName' to the 'name' node ..?
I want to put a attribute rvsn with a value 1 for the original 'FirstName' element Node.
so the new Element Node should look like the foloowing:
<form>
<name>
<FirstName rvsn="1"></FirstName>
<FirstName></FirstName>
<LastName></LastName>
</name>
</form>
Hopefully this is valid XML !!
when I tried to use appendChild, it removed the previous node and put the new one. Thats what is the documentation also said.. I read it after I tried it :(
Anyway, ther should be another way to add a node like that.
Any hints, ideas will be of great help.
-Thanks in advance !!

Problem replacing Null nodes with real values in XML documents...

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
Our friends in Java land are insisting on passing data between Java and PL/SQL using fairly small XML documents (don't ask). I then need to extract the input parameter values and pass them, on to the stored procedures that actually do the work. These return a result which needs to be returned to the java layer in the output XML document.
Here is a cut down version of the input XML...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
<Result xsi:nil="true"/>
</Parameter>
<Parameter>
<Id>2</Id>
<Result xsi:nil="true"/>
</Parameter>
</ParameterList>
and this is an example of what I am expected to return...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
*<Result>SUCCESS</Result>*
</Parameter>
<Parameter>
<Id>2</Id>
*<Result>WARNING</Result>*
</Parameter>
</ParameterList>
i.e. I am expected to replace the value of the Result node with a string indicating the succes or otherwise of the underlying PL/SQL process.
I am extracting the input values using the DBMS_XMLDOM functions and naively assumed that DBMS_XMLDOM.SETNODEVALUE could be used to update the value in the Result node - It didn't work so I resorted to reading the documentation which revealed that it will not work for a null node.
Am I going to have to use XSLT to generate the output XML from the Input and incorprate the result? Or is there a simpler way?
I have used XSLT in Oracle before and still have the nervous tick...

Thanks A Non,
With your suggestion and a bit of help from the w3schools.com xml dom tutorial I eventually managed to work out how to do this.

One question, why do the dbms_xmldom functions return the Old value? I was expecting the returned value to be the updated node.

Unable to add value to model node with cardinality 0..n

Hi All,
Im working with Webdynpro Java.i have an issue here.i have a input field item named customer and a drop down box item location.when i give customer and location as inputs,a WSDL (named Equipment WSDL) is called.the result is a drop down list containing equipments id
i took a custom node location with cardinaliy 0..n.i gave static values as input for location.i need to set the location values to model node location.when i m giving a single value to custom node location,that static value is not accepted by model node location(in WSDL) whose cardinality is 0..n.
Please suugest a solution for this issue
With Regards,
Ushasri.

HI Ushashri,
What do you mean by 'static value is not accepted by model node location'
how you have done the mapping
send me the hierarchy of rfc and ur value node

Replacing a value of a node with CDATA (as is)

Hi All,
How do I replace the value of a node such that it's CDATA format is preserved and not re-encoded. Currently, when I do similar to the following:
replace value of node doc(doc_name)/parent/node with "<![CDATA[[the data]]]>"
the less than and greater than signs are replaced with &lt ; and &gt ; respectively, losing its CDATA section status.
How do I replace the value such that within the resulting XML it is exactly "<![CDATA[[the data]]]>" and not "&lt ;[CDATA[]the data]]&gt ;" ?
Thanks in advance
Cecil

John,
I am aware that it's synatic sugar. However, I actually need it to look that way. Thing is after edits, the resulting XML will be read by a component (that I have no access to change) which requires that node to have CDATA (as is) as it's value.
Anymore ideas; Anyone?
Instead of replacing the value (ie. replace value of node doc()...), I replaced the node (ie. replace node doc()...) with something similar to: <node>CDATA-section</node>. However, as expected only the data within the CDATA section gets persisted.
In this case could I turn something off or on such that xmldb leaves the CDATA-section as is? e.g. http://www.xquery.com/tips_and_tricks/including_CDATA_in_results.html
Thanks,
Cecil

Hardcode values of the node with cardinality 0..n

Good day!
I need to hardcode a list of element to the node with cardinality 0..n.
Node has two attributes.
How can I fill the node with a few element in the input mapping? I know I can do it with a single element by separating values by comma. Is it possible to fill the node?

Hello.
I've the same problem. Can you say how to set list of values for a structure?
For example, we've node FIELD containing two attributes: ID and NAME.
FIELD is a node with cardinality 0..*. How to set at least two elements to the node?
Your example works only for simple attributes with cardinality 0..*, but it doesn't work for structures.

How to set values to the structure containing a node with cardinality 0..n

Hello.
I 'm trying to set values for the node with cardinality 0..n. The node type is "Fields".
<xsd:complexType name="Field">
   <xsd:sequence>
      <xsd:element name="fieldCode" type="xsd:string"></xsd:element>
      <xsd:element name="displayValue" type="xsd:string" minOccurs="0"></xsd:element>
   </xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Fields">
   <xsd:sequence>
      <xsd:element name="field" type="tns:Field" minOccurs="0" maxOccurs="unbounded"></xsd:element>
   </xsd:sequence>
</xsd:complexType>
I need to set several values for the element "fieldCode" but it has cardinality 0..1 and BPM does not allow it but I did not find any option about how to set values for the structure of type "Fields". Could you help me?
Best regards,
Timur Semenchuk

Hi Marcus,
If there is no way you could change the cardinality of the node, and thus it can contain 0..n items, I think you should create-and-add a new element programmatically.
Since the collection can contain zero elements, I would add a 'new' button, which upon clicking adds one new element via:
IYourNodeElement yourNodeElem = wdContext.nodeYourNode().createYourNodeElement();
wdContext.nodeYourNode().addElement(yourNodeElem);
Hope this explains a bit!

Navigate between View with Value Node.

Dear Expert,
    I would like to know the best way to carrying data in Webdynpro between View.
   For example, I have a Quiz applcation with 10 pages (View) of question. I would like to submit the answer at the end of the page (10th View).   So, at the end of the page, I need the to retreive the answer from page 1 to 10 and submit it.
1.   I am using copyToLocal. What that does it when the application fire Next event plug. it will
Quiz.<b>set</b>QuizAns1(Quiz.<b>get</b>QuizAns1)
and do the same thing for next 9 pages in order to bring the answer from page 1 to the end.
To simplfied, I am considering.
2. Model Beans
/people/valery.silaev/blog/2005/06/29/apojo--almostplain-old-java-objects-as-model
3. Session Beans.
     Is any concern that I shouldn't use session bean in webdynpro??
Or any other way to make the Code more organize?
Thanks all.

Hi,
The best way to carry data in WebDynpro views is through context attributes.
Create a context as below in component controller
Context
+Questions (node:cardinality 0..n,selection 0..n)
---Question
+Answers
---Ans (node:cardinality 0..n,selection 0..n)
Map the above context to all the views.
In the wdDoInit() of component controller create Ans elements under Answers node equal to question node.
for(int i=0;i<wdContext.nodeQuestions.size();i++)
wdContext.nodeAnswers().addElement(wdContext.nodeAnswers().createAnswersElement());
// This way we need not create the elements in each view before going to the next view.
Populate the Question attribute with Questions.
Through indexing show the question corresponding to views as
In first view (index 0)
wdContext.nodeQuestions.getQuestionsElementAt(<b>0</b>).getQuestion();
In second view (index 1)
wdContext.nodeQuestions.getQuestionsElementAt(<b>1</b>).getQuestion();
and so on..
// Note: The Answer node will not be populated intially with values as your answer might be multiple choice.
After the user gives answer store the answer in the corresponding index of Ans attribute under node Answers as
For the answer in first view
wdContext.nodeAnswers.getAnswersElementAt(<b>0</b>).setAns(<get the answer from the view>);
For the answer in second view
wdContext.nodeAnswers.getAnswersElementAt(<b>1</b>).getAns(<get the answer from the view>);
In your last view you can get the Questions and Answers by looping through the Questions and Answers node.
This way you will need only one attribute for Question and Answer respectively.
