Collecting and bundling messages - transformation n- 1 messages problem

Question

Hi guys,
I try to implement the scenario with collecting and bundling messages. I have a question: when you look at the samples in Basis6.40 SW Component, namespace http://sap.com/xi/XI/System/Patterns, there is an example, which uses message mapping BpmPatternCollectMerge.
My question is: how can this mapping work??? it is mapping of N messages into 1 of the same type!!
And when you try to test it, it does not work...
Can you help, how to solve it? Or any ideas for other possibilities, how to merge the messages?
Thanx, Peter

Hi,
To perform a N:1 transformation, these are the follwing important steps,
DESIGN
1. In your message mapping, make sure that the occurence of the source message interface is made to be n.
2. Likewise, in your Interface mapping, the occurence of the Source Message Interface should also be made N.
CONFIGURATION
If you are using SP14 or SP15, the mapping can be done without a BPM as follows,
u will have to go for a BPM with a receive step inside a loop with a multiline container element and the transformation step outside the loop to do the N:1 mapping
Hope this clarifies and helps,
Regards,
Bhavesh
