Message mapping problem / experts needed / UDF?

Question

Hello experts,
I have the following problem in a message mapping:
Source structure is as follows:
- Node a (min 1, max 999)
  - Subnode b (min 0, max 999)
  - Each Subnode b has the element "number" (1,1)
This structure must be mapped to the following target structure:
- Node c (1,999)
   - Subnode d (0,999)
   - Each subnode d has the following elements:
       - e1
       - e2
       - e3
       - e11
1 Source node a should create 1 target node c.
All numbers in all subnodes b of one source node a should be mapped to the e1, e2,...e11 elements of the target structure. As one target node d can only contain up to eleven numbers, there must be several d nodes.
I have already tried to create a UDF, but it does not work.
Any experts who would like to share their knowledge?
Thanks in advance.
CHRISTOPH

Answer 1

Hello again,
meanwhile I have worked hard on it and I have found the solution (just one UDF (queue function) which gets the article numbers as well as constant(targetField). So the UDF covers the creation of the "groups" as well as the mapping of the article numbers.
It was really interesting and it made me ambitious to find the solution myself I do not have access to the system today, but I will post my solution as far as I have access again. Maybe you still want to search for a solution? It really may be fun, just like some kind of a puzzle game.
In order to make it more clear, here comes the source and target structure with an example. Let me once more explain it: In the source, there are positions, each with unlimited article numbers. Each position will create a targetPosition. The node "targetPosition" has the subNode "articlenrs" (unbounded). Articlenrs has 11 differnet elements, calles a1, a2, a3, ..., a11. That means, all article numbers from a source postion should be mapped to "groups of 11 target article numbers". Please be aware the there are 11 differnet target fields for article numbers: a1, a2, ... a11.
I think that' why the solution of  Liang Ji and Rohit Kalugade will not work...
SOURCE
<position>
     <articlenr> 123   </articlenr>
     <articlenr> 456   </articlenr>
     <articlenr> 4783 </articlenr>
     <articlenr> 123   </articlenr>
     <articlenr> 456   </articlenr>
     <articlenr> 4783 </articlenr>
     <articlenr> 123   </articlenr>
     <articlenr> 456   </articlenr>
     <articlenr> 4783 </articlenr>
     <articlenr> 123   </articlenr>
     <articlenr> 496   </articlenr>
     <articlenr> 4783 </articlenr>
         . (unbounded)
</positon>
<position>
     <articlenr> 543  </articlenr>
     <articlenr> 865  </articlenr>
     <articlenr> 643  </articlenr>
</positon>
TARGET
<targetPosition>
  <articlenrs>
       <a1> 123  </a1>
       <a2> 456  </a2>
       <a3> 4783 </a3>
       <a11> 496 </a11>
  <articlenrs>
  <articlenrs>
       <a1>4783 </a1>
  </articlenrs>
</targetPosition>
<targetPosition>
     <articlenrs>
     <a1> 543 </a1>
     <a2> 865 </a2>
     <a3> 643 </a3>
        </articlenrs>
</targetPosition>
Thanks,
Christoph
