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
Result:
Hope this helps,
Mark

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

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.

Message mapping - Duplicate subtree

Hi Experts,
I am working on 7.0 server.
In the existing message mapping I found that target nodes are duplicated.
For example
/ns0:FiletoFile_ib_mt/Record/Emp[1]
/ns0:FiletoFile_ib_mt/Record/Emp
And the order for the node in the target message structure is same as above.
And in the output, the order is reversed as below
/ns0:FiletoFile_ib_mt/Record/Emp
/ns0:FiletoFile_ib_mt/Record/Emp[1]
But when am duplicating one more node in the existsing mapping the order is
/ns0:FiletoFile_ib_mt/Record/Emp[2]
/ns0:FiletoFile_ib_mt/Record/Emp[1]
/ns0:FiletoFile_ib_mt/Record/Emp
And now the output is
/ns0:FiletoFile_ib_mt/Record/Emp[2]
/ns0:FiletoFile_ib_mt/Record/Emp[1]
/ns0:FiletoFile_ib_mt/Record/Emp
But I need the output as
/ns0:FiletoFile_ib_mt/Record/Emp
/ns0:FiletoFile_ib_mt/Record/Emp[1]
/ns0:FiletoFile_ib_mt/Record/Emp[2]
Please let me know if you have faced similar issue.
If am creating a new message mapping and duplicating the subtrees the order is given below
/ns0:FiletoFile_ib_mt/Record/Emp
/ns0:FiletoFile_ib_mt/Record/Emp[1]
Why in the existing mapping duplicate subtree is going in the top order and for new message mapping duplicate subtree is going in the bottom. Please advice
Thanks
Suma S

Hi Lucas
I checked this sap note but I used PI 7.0.
This happens from 7.10 onwards and this is primarily due to the reason that the occurence of the duplicated node was not remembered when the mapping program gets executed. So, the mapping program was expecting data from the payload for the duplicated node and hence the error

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

How can I use loop in graphical message mapping

The source input XML is like:
<bookstore>
<book>
 <item1>xxx</item1>
 <item2>yyy</item2>
</book>
<book>
 <item1>zzz</item1>
 <item2>www</item2>
</book>
</bookstore>
I want to create an output XML like
<output>
 <item>
 <item1>xxx</item1>
 <item2>yyy</item2>
 </item>
 <item>
 <item1>xxx</item1>
 <item2>www</item2>
 </item>
 <item>
 <item1>zzz</item1>
 <item2>www</item2>
 </item>
 <item>
 <item1>xxx</item1>
 <item2>yyy</item2>
 </item>
</output>
That means I want to do permutation and combination for all <item1> <item2> under <book>.
Of course I can write a customer function to do it, but I want to basically use the buildin functions to do the graphical message mapping for this.
Any idea? thank you.

well, I'm not very clear of those 2 English words
What I want is to list all possible combination of item1 and item2 (and in fact, we have item3, item4, ....etc).
example
input:
<item>
 <item1> 111 </item1>
 <item2> 222 </item2>
 <item3> 333 </item3>
</item>
<item>
 <item1> aaa </item1>
 <item2> bbb </item2>
 <item3> ccc </item3>
</item>
I want to get
<item><Item1>111>/item1> <item2>222</item2> <item3>333</item3> </item>
<item><Item1>111>/item1> <item2>222</item2> <item3>ccc</item3> </item>
<item><Item1>111>/item1> <item2>bbb</item2> <item3>333</item3> </item>
<item><Item1>111>/item1> <item2>bbb</item2> <item3>ccc</item3> </item>
<item><Item1>aaa>/item1> <item2>222</item2> <item3>333</item3> </item>
<item><Item1>aaa>/item1> <item2>222</item2> <item3>ccc</item3> </item>
<item><Item1>aaa>/item1> <item2>bbb</item2> <item3>333</item3> </item>
<item><Item1>aaa>/item1> <item2>bbb</item2> <item3>ccc</item3> </item>

How to use analytical functions inside a mapping

Hello everybody. Here Isend you a trick that we are using for two years.
If you want to use a function (for instance :ROW_NUMBER() OVER (PARTITION BY ... ORDER BY ...)) inside a mapping you must create an expression with in the INGRP1 the fields you are going to use in the window function and in the OUTGRP1 the function you want. Create an Out -attribute with the expressión and link it to a distinct operator (using a "distinct" you encapsulte the sql and you will be able to use the function inside a filter - in the where clause.). The distinct can eliminate some register (depends on the function). If you validate the expression an error will appear (don't worry about that, the mapping will be ok).
But there is a limitation, you will not be able tou sum over, min over, max over (it detect that they are aggregator functions). Other limitation: the debugger doesn't run with this kind of functions.
Please publish this information on "The Warehouse Builder Utility Exchange". Mi email is [email protected] (if you need more information)

It is possible to add SUM, MIN, MAX functions also to OWB releases prior to Paris - You have to put them in double quotes - write "MIN" "MAX" "SUM" etc. The rest of the rules (adding cut-off operator after the expression - as DISTINCT, or UNION ALL) is analogical to with ROW_NUMBER()
That means You can create mapping with following functionality:
SELECT
sum (salary) over (partition by DEPARTMENT) department_salary,
salary,
employee_id,
employee_name
FROM employees_salaries
writing it this way in OWB:
SELECT
"SUM" (salary) over (partition by DEPARTMENT) department_salary,
salary,
employee_id,
employee_name
FROM employees_salaries

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,

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.

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.

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
