Hi Vamsi,

A multi-mapping is a mapping program that is not restricted to the transformation of one source message to one target message.

mappings of below type can be called multi mapping:

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

chk out the details:

don't forget to also refer the threads below for the similar concern:

Hope this was helpful....

It is mapping multiple structures with 1 (n:1) or mapping a single structure with many (1:n)

Both the cases could be handled using BPM. But 1:N can also be handled without BPM.

Hi,

What is the Use of This Multi Mapping in Real time ??

Please Can Any one Explain Using Example.

e.g. Suppose a sender file has many records. Then u may want to create Idoc for each record at SAP. In this scenario, u may implement multi-mapping (1:N)

Multi-Mapping can only be used in ccBPM. It is used to map abstract interfaces. Development is the same as Message Mappings

n:1 Transformation

Bundles multiple messages into one message, for example, individual purchase order items into one purchase order.

1:n Transformation

Splits a message into multiple messages, for example, a purchase order into the individual purchase order items.

n:m Transformation

Converts a message into another message, for example, a message that is defined by interface A is converted to message that is defined by interface B.

Multi-Mappings reference multiple message structures:-

a) All source message structures are combined into 1 source structure.

b) All target message structures are combined into 1 target structure.

Therefore, there is only one source structure mapped to one target.
