Hi Naresh,

MultiMapping the name itself..specifying we can map the multiple sources to single target.. and single source to multiple targets .. for example ..If you want to send the single file to multiple receivers then we can go for a multimapping..

for details.. just go thru this blog..

/people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible

Few very important points which you should know before using the multimapping without BPM are as below:

1. Multimapping without BPM is possible if you have SP14.

2. Multimapping without BPM is possible only for 1:N scenario.

3. For N:1 scenarion you have to use BPM.

4. Multimapping without BPM is possible ONLY for those adapters which resides in the Java Stack.

Hi Ajay,

To send message to multiple receivers You dont have to go for multi mapping it can be done by configuration also .

But when It is required to split or join messages,in terms of messages, then it will be more helpful.

Please correct, If I am wrong.

Hi Naresh,

Multi Mapping as the name suggests consist up of multiple inout messages or multiple output messages.

In normal mapping You have single inoput message and single ouput message but wehen any of this is changed to multiple messages like one inout and 2 output messages then it is termed as Multi Mapping.

Also various more definition can be searched in SDN.

HI,

A multi-mapping is a mapping program that is not restricted to the transformation of one source message to one target message. You have the following options:

1) You can use a multi-mapping in a transformation step in a integration process. In this case, the mapping runtime supports 1:n-, n:1, and n:m transformations. You can map any number of source messages to any number of target messages.

2) You can use a multi-mapping to map a message to multiple different (and generally smaller) messages during logical routing. Only a 1:n transformation is possible in this case.

refer the below link for more information:

For example if u wanted to split the IDOC into N no of IDOC then u can do with multimapping.
