Hi -

Used in mapping based message splits (1:n) as shown here (/people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible) and then only in BPM transformation steps where the mapping ratio for source to target messages can be m:n.

At a high level, aside from the mapping based message split scenario where BPM isn't used, multi-mappings are most commonly used in BPM split (1:n) or merge (n:1) scenarios.

Regards,

Jin

say u have two soruce message and one target. u wud want to map the 2 soruce to target and this kind of mapping is acheieved via multimapping. it can be of:

1. 1:N

2. N:1

3. M:N

So, mappings like

1. 1:N --> 1 source message and N target messages

2. N:1 --> N source messages and 1 target messages

3 M:N --> M number of source messages and N number of target messages

are referred as MultiMappins.

Mapping 1 can be achieved without BPM whereas others need to have a BPM.
