File to Proxy: FCC and mapping to generic proxy target structure

Hi experts,

I have a question regarding a File to Proxy scenario which uses FCC.

We have a source file which contains different rows of different structure, like:

HDR:123:Test:783:1000:20130101:HBA’

REC1:Test:20130404:Description’

REC1:Test:20130820:Description2’

REC2:GBR:Test:20130810’

…

The number of record types can vary (except the HDR record which only occurs once).

The XML structure after FCC looks as follows:

<Header>

     Contains HDR record type fields

</Header

<Item_REC1>

     Contains REC1 record type fields of occurrence 1 in file

</Item_REC1>

<Item_REC1>

     Contains REC1 record type fields of occurrence 2 in file

</Item_REC1>

<Item_REC2>

     Contains REC2 record type fields of occurrence 1 in file

</Item_REC2>

…

This file needs to be transferred into a generic proxy structure which has one header and a 1:n sub-structure which holds a subset of all fields of all different record types REC1, REC2, REC3, etc.

The format looks as follows:

Header                           (should hold HDR record)

   |__Item 1                   (should hold all other record types, like REC1, REC2, REC3, etc.)

   |__Item 2

   |__Item 3

As mentioned sub-structure Item contains specific fields of all record types, means all record types (except HDR) need to be mapped to this generic structure.

How do I achieve this?

Thanks a lot for your help.
