Help!! - File to Idoc Mapping with Nested structure

Question

Scenario:
I have an inbound file that has three nested records.
eg. A00, B00 and C00. C00 is nested structure of B00 and B00 nested structure of A00. All these structure can repeat N number of times in a file.
How do I map this to IDoc structure that have one segment each for the three structures in the file and nested in the same way.
Question: How is the parent child relationship established?
     Suppose I have a file
     A00 1234 Sam 29
          B00 london LE3 XYZ
          B00 US 123456
                C00 2 XYZ
           A00 5678 Joe 22
        B00 US 23456
     If I make a nested structure and then say in the file conversion properties that A00 go to segA and then B00 go to segB, but then when I come back to A00, how do I move the data to the A00?
Thanks in Advance

Answer 1

From what you have layed out, you can create a data type with 3 children, all 1..unbounded cardinality, each containing their own elements.  You say they are nested, but the example you gave isn't nested... it's just A's followed by B's followed by C's.  If that is the case, you can then use a data type w/ 3 subelements (A, B & C) and each of those is actually a container with the real attributes of that line in your file.  (I can email you a schema quickly if you need it)
If you are saying they can occur like this:
A00 1234 Sam 29
B00 london LE3 XYZ
B00 US 123456
C00 2 XYZ
B00 US 23456
C00 2 XYZ
THEN they are nested - ie B's & C's repeat under any A.  Then you must create segment B as a subelement of segment A instead of on the same level, then bury C under B. (I find this easiest w/ a text tool rather than inside XI, as I can cut/paste segments where I want them to belong...)
Good luck with setting up content conversion on that file adapter... We have done this a few times, and it can be quite interesting.
If you have trouble with the schema, you can post your email & I can give you a quick example.
