Mapping problem - how to map unbound types to destination???

Hi All,

I am new to XI, facing a little problem while mapping:

I have a scenario where I need to map from the source Message type:

head - 1..1

itemn - 0..unbound

to a destination Message type:

head - 1..1

item - 1..1

where, if the source message type has the values:

head - HEADER1

itemn- ITEM1

ITEM2

ITEM3

ITEM4

<there could be any number of items here>

A destination message type should be created with the following values:

head - HEADER1

item - ITEM1

head - HEADER1

item - ITEM2

head - HEADER1

item - ITEM3

head - HEADER1

item - ITEM4

The number of nodes here should depend on the number of items in the itemn field (which is unbound. i.e. it can take the values dynimically).

Please help me with this.
