Hi,
i am getting small problem in the context change..
i have input as

5
[5]conext change
6
7

[8]context change
my requirement is the element after context change in the input sholud be deleted.
Thank you,
Madhav.

Hi Madhav,
Try This
for(int i=0;i<a.length;i++)
if(a<i>.equals(ResultList.CC))
result.addValue(ResultList.CC);
i++ ;
else
result.addValue(a<i>);
"if(a.equals(ResultList.CC))" it should be a(i) but in rect bracket ,Dont know why it is not showing the same in above code
Thanks

Mapping query for context change without UDF

Hi,
My requirement is as below:
Input queues are
4319, 4319,4320,4321,4321
M1,M1,M1,M2,M2,M2
Required output is
4319,4320,CC,4321
COntext change is to be inserted when there is a change in value in second queue.
regards, Anirudh.

Hi,
Have you tried using the formatByExample as specified?
input1-->removeContext--> concat --> splitByValue:ValueChanged --> collapseContext --> substring (2..6) --> formatByExample (1) --> Target
input2-->removeContext--> /
input1-->removeContext--> concat --> splitByValue:ValueChanged --> collapseContext --> substring (0..2) --> splitByValue:ValueChanged -->formatByExample (2)
input2-->removeContext--> /
code explanation
input1 and input 2 when concatted outputs M12319,M12319,M12320,M22321,M22321,M22321
The upper part of the code does this: M12319,M12320,M22321, when you use the substring it outputs now 2319,2320,2321
The lower part of the code does this: M12319,M12320,M22321, when you use the substring it outputs
M1,M1,M2, then you use splitByValue. The output is now M1,M1,CC,M2.
When you input the code from the upper part and lower part into a formatByExample node, the output becomes
2319,2320,CC,2321
Hope this helps,

Error message: "Querying or saving changes to the database failed."

Hi all,
I can sense I'm becoming a regular on this particular forum - the problem of spending 8 hours a day trying to get this software working!
_*The problem*_
When i try and setup a new device, or modify an existing one, I get an error message when i get to the Transcode Settings page. The error message is "Querying or saving changes to the database failed." After this I get a blank screen and can no longer see my settings.
No amount of restarting has fixed this. And I cannot see a way to create a device through the client software and add transcode settings.
Help?
Thanks in advance,
Ben

Ah very good!
Ok - it seems then that this works absolutely fine as a work around. I can create a device and then assign the device to transcode settings through the client adminsitration panel (which is indeed what I meant).
So, there is a work around. Far less pressing now, but I would like to know why I'm getting the error message all the same - I'm now concerned about the integrity of the database...
Thanks Tony!

Context change by DOM parsing Java Mapping in XI

Hi Team,
I would like to know that how can I handle Context Change by DOM Parser Java Mapping in XI.?
Suppose the source XML structure I have like below:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Header xmlns:ns0="urn:bp:xi:hr:edm:test:100">
   <FileName>
      <filesub>
         <subname>a</subname>
         <subname>b</subname>
         <subname>c</subname>
      </filesub>
   </FileName>
   <FileName>
      <filesub>
         <subname>d</subname>
         <subname>e</subname>
         <subname>f</subname>
      </filesub>
   </FileName>
</ns0:Header>
Where the field FileName can occur maximum thrice(0...3) but the subname field is (0....unbounded) but in the target source I would like to have as given below:
<?xml version="1.0" encoding="UTF-8" ?>
- <MT_Test4 xmlns="urn:bp:xi:hr:edm:test:100">
- <Header>
<FileName>a</FileName>
<FileName1>d</FileName1>
    </Header>
- <Header>
<FileName>b</FileName>
<FileName1>e</FileName1>
   </Header>
Header>
<FileName>c</FileName>
<FileName1>f</FileName1>
   </Header>
</MT_Test4>
That means the first value from every context of the source field is forming my first and second value in my target first context.Thensecond value from every context is forming my 1st and 2nd value of my target 2nd context and finally 3rd value of every context is forming my 1st and 2nd value of my target 3rd context.Is this possible to done through DOM parsing or we have to do it by UDF only?

one more thing in this line "textChild=docOut.createTextNode(s k + j );"   somehow the the third braces one opening before k and one closing after j is missing for unknown reasons. Please correct it when you actually run this code.

wat is context and how it changes?

Hi,
Assume u have message type as follows.
i.e MTO_Sample-
       -Data1
          - filed1
          - filed2
          - filed3

    -Data N
          - filed1
          - filed2
         - filed3
where Data1, Data2 and Date3 are context..
assume u have Data1 with 2 records, then start of second record nothing but context change.
please chk the following link.

Hi,
what is context change?? where it is implemented?
thanks in advance.

Hi!

User changes in tab strip ui element are not recorded in context change log

Hi All,
We are using a tab strip ui element in webdynpro component. But user changes inside tab strip ui element are not getting recorded to the context change log. I have an input field on the same view besides tab strip ui element. User changes to this input field are getting recorded to the context change log.
Is there any restriction on context change log usage with tab strip ui element?
Could you please suggest If there is any way to record changes inside tab strip ui element.
Thanks,
Sudheer.

I think there are some limitations exists, context change logs are not complete when you do value help , i am not sure about tab strip.

Please send tables structures and sample data from that tables. And, of course what should be the output. :) Just sending your query won't help us to find a solution.

Add a context change after a set of values in a context

Dear experts,
My requirement is as follows:
Scenario: Idoc to Idoc. I need to check if there are line items > 5- I need to do a split. The split is happening properly via my mapping but I have a problem at the header record level on the target- I do not get the values populated correctly. I need to add a context change after 5 values in the queue.
eg:
Say there are 2 Idocs at the source with following unique IDs: called Journal ID:
My source:
Idoc 1: Journal ID 123
Line Itme 1
Line Item 2
Idoc 2: Journal ID 124
Line item 1
Line item 2
Line item 3
Line item 4
Line item 5
Line item 6
Line item 7
So I need to get total of three Idocs in my target:
Idoc 1: Journal Entry 123
Line Item 1
Line Item 2
Idoc2: Journal Entry 124
Line item 1
Line item 2
Line item 3
Line item 4
Line item 5
Idoc3: Journal entry 124
Line item 6(new 1)
Line item 7(new 2)
The split in the target Idoc is working perfectly. But inside the header record the journal ID field(taken from Item record level) is not populating correctly. I am getting this output:
Idoc 1: Journal Entry 123
Header Record-->JournalID Field value= '123'
Line Item 1
Line Item 2
Idoc2: Journal Entry 124
Header Record-->JournalID Field value= '124'
Line item 1
Line item 2
Line item 3
Line item 4
Line item 5
Idoc3: Journal entry 124
Header Record-->JournalID Field value= Null
Line item 6(new 1)
Line item 7(new 2)
So please suggest a UDF/standard function to populate the right values inside header record--->Journal ID field.Something like the below...
public void calculate(String[] var1, ResultList result, Container container) throws StreamTransformationException{
for ( int i = 0; i < var1.length; i++ )
if( var1[i].length() > 5) //here var1 I am passing the Journal ID
result.addContextChange();
Apparently this doesnt work.

The first Idoc has two line items and the second idoc has 7 line items. As the split is per 5 line item- the target has 3 Idocs.
Now the problem is that the header value in the target: REF_DOC_NO has to be created as per the number of line items and doesnt come from header record directly.

Transport of Query successful, but changes not appeared in the report

Hi All,
I have 2 Queries(Normal and Total stock reports on the same InfoProvider) in Prd.
For that User asked me to add one characteristic to Free characteristics.
I added one characteristic in Free Characteristics to both Queries in Dev and i collected the Transport requests for both the queries in RSA1->TRANSPORT CONNECTIONS and gave it to basis guy, he transported successfully to PRD and for both the reports the changes reflected in the
query designer, while executed the Normal stock report the characteristic added in free characteristics appeared and while drill down the data is coming, but for the Total stock report the changes appeared in Query designer but on executing the report even the characteristic added to Freecharacteristics is not appearing in Navigation Pane.
Also with the same technical name of total stock report there are 2 reports appearing in query designer. what to do now.
Help me here asap..
Thanks,
Chaitu.

Hi Chaithu,
As you mentioned that you can see 2 versions by the same technical name in designer for total stock report, it is highly probable that the query you are changing and the query you are executing are different.
2 versions of a query can exist with the same technical name as the system identifies the queries by their UIDs, which would be different for both these versions of queries.Following are the things you need to check:
1) In development system too, do you have 2 versions?
2) In production system, check the UID for both verions of the query
3) In Dev system, make sure you modify the query with UID which is being executed, if it is available there. Else, you need to replace the query in prod with the one you have in Dev system.
2 versions by same technical name can exist if:
1) Someone created a query directly in Prod, and transported a query by same technical name from Dev system
2) or due to system refresh, copy, etc.
Hope it helps.
Thanks,
Abhishek.

Message Mapping - Initialize counter every context change

Hi all,
is there any way to develop a counter customer function in a graphical message mapping so every context change of a field the counter initializes?
Imagine i have the following structure:
1 DATA
1.1 DETAIL
1.2 DETAIL
2 DATA
2.1 DETAIL
2.2 DETAIL
and i wanna count DETAIL fields but initialize the counter every DATA field. Is there any way to do it?
Thanks a lot.

Hi,
If your Source structure is
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_DATA xmlns:ns0="http://yash.com.YH1309">
   <DATA>
      <DETAIL/>
      <DETAIL/>
   </DATA>
   <DATA>
      <DETAIL/>
      <DETAIL/>
      <DETAIL/>
   </DATA>
</ns0:MT_DATA>
and You want the Target as
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_DATA xmlns:ns0="http://yash.com.YH1309">
   <DATA>
      <DETAIL>COUNTER=1</DETAIL>

   <DATA>
      <DETAIL>COUNTER=1</DETAIL>
      <DETAIL>COUNTER=2</DETAIL>
      <DETAIL>COUNTER=3</DETAIL>
   </DATA>
</ns0:MT_DATA>
Create the below UDF with one argument (DETAIL) and select Execution type all values of a Context
for (int i =1;i<=DETAIL.length;i++)
result.addValue("COUNTER=" + i);
but if you want Your Target as
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_DATA xmlns:ns0="http://yash.com.YH1309">
   <DATA>
      <DETAIL>1</DETAIL>
