Message mapping problem

Hi All

I have a message mapping problem that I would like help with please:

I have a list of rows from a JDBC source that I need to map to an IDOC (ORDERS05)

The source file looks like:

HeaderID  LineType  Value

1               HDR            NULL

1               LINE1          NULL
1               LINE2          15

1               LINE3          15

2               HDR            NULL

2               LINE1          NULL

2               LINE2          20

2               LINE3          20

2               LINE2          8

2               LINE3          8

I split each change in HeaderID into a new IDOC by using:

HeaderID -> removeContext -> sort -> SplitByValue (value change) -> collapseContext -> IDOC

So this is giving me 2 separate IDOCS - which is great.

My problem is that I also need to be able to create a node in each IDOC only for each LINE3 that appears

So in the above the IDOC split would be:

1     LINE3     15

2     LINE3     20

       LINE3     8

I've tried various options but cannot work out a way to do this?

If you are able to help a detailed answer would be great.

Thanks in advance

Mark
