Message Mapping RFC structure to deep XML structure

Question

Hello,
I have a message mapping I am struggling with. The outbound interface is an RFC with structure like this:
RFC_send_material
-material (1..unbounded)
--matnr
--meins
--brgew
-description (1..unbounded)
--matnr
--vkorg
--text
The inbound interface should look like this:
Materials_from_SAP
-material (1..unbounded)
--matnr
--meins
--brgew
--description (0..unbounded)
---vkorg
---text
My problem is to get all the description connected to the matnr together.
Examples with data:
Outbound rfc:
<RFC_send_material>
   <material>
      <matnr>100</matnr>
      <meins>c1</code1>
      <brgew>c2</code2>
   </material>
   <material>
      <matnr>101</matnr>
      <meins>c1a</code1>
      <brgew>c2a</code2>
   </material>
   <material>
      <matnr>102</matnr>
      <meins>bv102</code1>
      <brgew>addd102</code2>
   </material>
   <description>
      <matnr>100</matnr>
      <vkorg>NO10</sales_org>
      <text>testing100</text>
   </description>
   <description>
      <matnr>102</matnr>
      <vkorg>SE10</sales_org>
      <text>testing102</text>
   </description>
   <description>
      <matnr>102</matnr>
      <vkorg>DK10</sales_org>
      <text>testing103</text>
   </description>
</RFC_send_material>
The inbound file structure should then look like this:
<Materials_from_SAP>
   <material>
      <matnr>100</matnr>
      <meins>c1</meins>
      <brgew>c2</brgew>
      <description>
         <vkorg>NO10</vkorg>
         <text>testing100</text>
      </description>
   </material>
   <material>
      <matnr>101</matnr>
      <meins>c1a</meins>
      <brgew>c2a</brgew>
   </material>
   <material>
      <matnr>102</matnr>
      <meins>bv102</meins>
      <brgew>addd102</brgew>
      <description>
         <vkorg>SE10</vkorg>
         <text>testing102</text>
      </description>
      <description>
         <vkorg>DK10</sales_org>
         <text>testing103</text>
      </description>
   </material>
</Materials_from_SAP>
So as you see, my problem is to get the correct description belonging to the material. Hope anybody can help with doing this in Message Mapping.

Hi PRW,
As Michal said correctly, it is hard to describe in words, so here are some pictures which I think is the solution of your problem.
