I have a proxy to file scenario where I can not have the proxy changed, The input from the proxy is as follows (note: the field IntID is never mapped).

I need the output to be a single node as it has to go through content conversion. My output structure looks like this:

I have tried "use one as many" with the VKORG and SORT2 fields, but what I get in the output is just one set of Rawitem records (just for that combination of VKORG/SORT2), not all the Rawitem records. I then tried to map to one structure of the format:
<Records>
<Rawitems>
And then map that to just <Records> in a separate mapping, but I run in to the issue where I lose context. And I need to just have one context at the end, since this needs to go through content conversion. One final note: XSL mapping is not a skill I possess.
Thanks,
Dave
