Node functions in Message Mapping

Hi,
Could someone help me with some good exercises for node functions such as splitbyvalue, collapsecontents, removecontexts.
I am a newbie to these functions and have absolutely no idea on how to use them. Would appreciate if someone could give very detailed examples to these functions in a step by step manner, so that I can create them just by following your instructions.
Any links to video presentations are welcome too.
Cheers,
S

Hi ,
For a fresher, the informationa and examples given in the help.com would be more helpful and it will help you in building string fundamentals. Once your basics and funcdamentals concepts becomes strong then you can go for more complex exmples. Here is help.sap link where you can leran Node functions of MM of PI.

 Item 1..unbound
 Inventory 0..1
 UnrestrictedUseQuantity 0..1
The Group_ZA comes 'n' number of times and D02_ZA comes sometimes 5 times and sometimes 6 times etc.,
ZA_01 field can come with 5 to 6 different values like 'QA','QD','QN' etc., sometimes ZA_01 comes only 3 times QA,QD,QN.
if ZA_01 = 'QA' then only we need to pass ZA_02 value on to ''UnrestictedUseQuantity'' (target side),
I mapped the fields, the vlaue ZA_02 passing properly on to 'UnrestictedUseQuantity' when D02_ZA comes 5 or 6 times, all the times 'QA' value comes into ZA_01 field. In case if QA value missed or doesn't come from source, the Target side ' 'UnrestictedUseQuantity' field last value comes into last but one.
Ex: QA value is in 3 times, but I have 4 source message on top. values comes into target side like
20

suppose to come like

Please required your valuable inputs in bit urget !!
how to map field level please?

Petre:
If you want to use standard functions then you try this:
If-->currentdate -OR- Constant(01.02)
currentdate -OR- Constant(02.02) --> OR -->
currentdate -OR- Constant(03.02)
Then give some output
Else give some output
So give the output for the first two conditions to another OR and the result of the third to the same OR. So whenever the condition is true in any of the condition you will get the THEN value else you will get the ELSE value.

Count-Function in Message Mapping

Hey, trying to map following structures:
message
-m1
--m11
-m2
--m22
-m3
--m33
to
message
-m1
--m11
-m2
--m22
-m3
--m33
-f1
--countItems
The nodes m1,m2 and m3 can appear 1..unbounded. In target structure I would
like to have the numbers of all nodes (m1,m2,m3).
For example: In this source structure m1,m2,m3 appear only one time. In the
field countItems I would like to have the number 3.
I tried the count function, but it could only count the structure where I used it (in
this case: f1).
How can I count the above-mentioned nodes?
thanks
chris

Hey,
thanks for your answers.
But I still couldn't understand how to do this. I open the message mapping for field f1, but the count function could only be set on an target-element, so where to set the counters for m1,m2,m3? Do I have to insert extra fields under m1..m3?
If I do the counter would increment with every node, so if I have two times m1, in second tree of m1 a two will be insert. If I use the add function, only for these two tree the result would be three!
@Gangisetty Vijaya Bhaskarudu
Is this just one UDF? From where he knows, which nodes he have to count, if I have more than m1..m3, but only want to count this three?
@ sasitharan
same problem as mentioned above:
this doesn't work:
m1--count---\
I can't use m1 as input for count! Or do I have a wrong count function?
....au damm, answered my own question. Of course. I use COUNTER and you use
COUNT!!!!!!!!!!!! I will try this with COUNT!!
thanks
chris

Using useOneAsMany function in Message Mapping if subtree is optional

Hi,
I am trying to develop a message mapping for the following case:
In the source message, there is a value "Value1" which is on the same level as a subtree "Struct2" which can occur 0..unbound times
In the target message the value "Value1" has to be part of that subtree, so it has to be copied for each occurence of "Struct2" in the source message
For the case that the subtree has cardinality 1..n there are some examples on the web, e.g. useOneAsMany (SAP-Bibliothek - Partner Connectivity Kit). But that does not fit my case. The subtree in the source message is optional here.
See a screenshot of the message mapping and my solution for the mapping of "Value1" below:
All other values are mapped 1:1.
Sadly, this solution does not work when "Struct2" has cardinality 0..unbound, for 1..unbound it works perfectly. Here is my example:
When I try the mapping, I get the following error message:
That is true. The first queue of the useOneAsMany function has more values than the second. But I don't know how I can fix it, so that it works for my example. Can anyone give me a hint please?
Setup is AEX 7.31.

Hi Stefan,
You can use this mapping.
And for Struct2-Value1

Hope this helps,

Element/ Node supression in message mapping

Hi,
Source Structure
ID (Mandatory)
FName (optional)
Target Structure
EmpID (mandatory)
EmpName (optional)
In my mapping, i mapped FName to EmpName. Since FName is optional,when i have an XML file that does not contain Name element my message mapping fails. So i used "if-then-else" and "exists" to make the mapping work.
Name --> "exists" -->"if-then-else",
FName--> EmpName (then)
Constant-->EmpName(else)
But now i want that my o/p element (EmpName) should not get generated, if Name element does not exist. I mean the element Empname should be supressed in message mapping.
I know that if a target field is mapped, it is bound to come in the target structure. But i want this target element to be supressed.
Hope somebody can help me out...
Cheers,
Siva Maranani

Hi Siva,
If i understand u correctly you want to supress the target field if the mapped source field does not exist:
Try using IF WITHOUT ELSE
When the source field exists then you will have the value mapped to the target field and when the source field does not exist, the target field will not be created.

Sridhar

Generating target nodes dynamically in message mapping

Hi XI GURUS
I am trying to generate target node using using more then source node. Is it possible to do this.
I need this as in source I have 2 different nodes (0 to unbounded) and in target I want to create corresponding number of target nodes. For e.g if I have 2 + 1 nodes in source then I want to create 3 nodes in target
Source as below
<FIRSTNAME>
 <Raj>
 <Kum>
</FIRSTNAME>
<FIRSTNAME>
 <Naveen>
 <Kumar>
</FIRSTNAME>
<CITY>
<bANGALORE>
</CITY>
Desired output in target as below
<ADDRESS>
<qwerty1>
<ADDRESS>
<ADDRESS>
<qwerty2>
<ADDRESS>
<ADDRESS>
<qwerty2>
<ADDRESS>
Can i follow an alternative approach (using java function) of counting the total number of occurences of source nodes and generating as many number of the target node
Thanx

If you have a condition check for each of the source node to be mapped to the target node,
use "create if" standard function and pass the boolean result of your Condition check as an input to this standard function. For each "true" a value would be added to the output queue. If you have a simple condition check on some source field value for each correspoding node, use "if without else" or depending on the complexity of the condition you may use a udf to get the boolean outcome.
And for mapping from more than on type of source node, you may duplicate subtree for target node.

Creating new nodes dynamically in message mapping

Gurus,
Source Structure is
<Phone></Phone>
<Phone></Phone>
And I want to create target structure as for this Node1
<Phones>
<Phone1>Has value from first Phone Node in source</Phone1>
<Phone2>Has value from second Phone Node in source</Phone2>
</Phones>
The requirement is that I want to create <Phone1><Phone2> .........<PhoneN> nodes dynamically based on the number of <Phone> nodes in Source Structure. The cardinality of <Phone> node in Source is 0 to Unbound.
Any suggestion ...?
Thanking you all in advance.

Hi Ivan,
Since you have enter the xslt mapping in Message Interface mapping and both Message Interfaces (target and source) are tied with the message type. And in message type you have fixed schema, do you think it still possible to use xslt mapping to generate some of the target nodes dynamically (the nodes which are not part of MessageType/DataType)....thx?

How to use or function in Message Mapping?

Hi! I was wondering if anyone can show me how to use the or function.
Im trying to match the current date to three possible values so i need three or functions.
EG. if ( currentDate == 01.02 || currentDate = 02.02 || currentDate = 03.02 ) {
do something;

Petre:
If you want to use standard functions then you try this:
If-->currentdate -OR- Constant(01.02)
currentdate -OR- Constant(02.02) --> OR -->
currentdate -OR- Constant(03.02)
Then give some output
Else give some output
So give the output for the first two conditions to another OR and the result of the third to the same OR. So whenever the condition is true in any of the condition you will get the THEN value else you will get the ELSE value.

Defing user defined function in message mapping

hi experts of xi.
i want to create UDF for counting no of records in body and checking with trailer countinfo and adding all contract account amounts in file body and checking with trailer sum.
if these 2 comparings r not matched then we have to set flag field 'N' else we have to set as Y'.
waiting for ur answer.
regards.
seeta ram.

Hi,
pretty easy if you want to count number of lines (records)
two inputs (trailer and line segment)
and you can just compare it inside
then you can just return Y or N

New line in concat function in message mapping

Did any1 succeded adding 2 xml elemnts with LF/CR ( new line ) between them?
so when I use content conversion to txt file it will put new line between this 2 elements?
I tried the following delimiters
'0x0D''0x0A'
'nl'
''0x0D''''0x0A''
nothing worked
thx
Shai

Shai,
Here is a simple udf for adding a new line between two fields. Similarly you can extend it.
Create a "Value" UDF as name "input" and add two arguments 'a' and 'b'.
Add this code:
String lines;
lines = "";
lines = lines.concat(a + '\n' + b + '\n' );
return lines;
Also while testing in test tab if you dont see the new line in the ouptut then view the source of the output. There you can see the new line.

Functions at Message Mapping - Concatenate with If

Dear SAP Masters, please kindly help me to solve this case.
Please guide me how to achieve this :

Column2 = Sales Order Item number
Column3 = Sales Order Type
Column4 =
For each line, if Column3 start with "ZOR" then column 4 = concatenate Column 1 (SO No) with Column2 (SO Item No), else then Column4 = <blank>
Please kindly give me an idea.

Message Mapping (user-defined function)

Hi all,
Is there anyway to determine the XML message ID using an user-defined function in Message Mapping? When I go to SXI_MONITOR I see that all messages have an unique ID, but I'm having some difficulties to understand if there is any way to get that ID in a message mapping and pass it to a target structure? I see that it is possible to use constants like "Sender" and "Receiver", but I haven't found anything for the message ID.
Can you please help me?
Thanks in advance.
Regards,
Ricardo Inácio

Try this code..
Create an UDF and do not pass any arguments to it..
java.util.Map map;
// get runtime constant map
map = container.getTransformationParameters();
// get value of header field by using variable key
String msgid = (String) map.get(StreamTransformationConstants.MESSAGE_ID);
return msgid;
Now map this udf to your target field. Now test it....
P.s. Since message id is run time property therefore in mapping test tab it will not work. Try it at runtime.

Sarvesh
