mapping

[Former Member]

hi all , what is the use of the different type of mapping? is graphical mapping not enoug?

one more questions.

consider data transfer from sys a to sys b, how exactly does the messge flow .

when sys A sends a message does it goes to the sender adapter or to IE and from there does it goes to saender adapter.

please clarify my doubt.

Hi

Java mapping used for complex mappings

Graphical mapping for large amount of data using queues

XSLT used to transform XML family of messages

Core abapers can even use ABAP mapping

Hi,

First of all there are four different types of mapping:

Graphical mapping

Java mapping

XSLT mapping

ABAP mapping

Of all these mappings performance vice graphical mapping is the best. It can handle large volumes of data. But there are many situations where complex mappings coming into picture. in such situations graphical mapping may not be sufficient to handle the situations, and we have to use other types. In java mapping we can easily exceptions too. XSLT mapping cannot used for handling large volumes due to memory overhead. In case of mapping with tables in R/3 side we can go for ABAP mapping.

IE can accept only SAP XML format. For converting the message into SAP compatible forms we are using adapters in sender side and in receiver side it will convert the SAP XML format to the compatible form of corresponding receivers. So first it will go to sender adapter which contains some module to convert to SAP XML format and then the processing takes place in IE.

Hope this helps you out.

Thanks and Regards,

Vineetha

Deepa,

At times mapping can become too nested and difficult with complex context handling in the case of graphical mapping.

In such cases, java / XSL / ABAP mapping allow for simpler and easier mappings.

All messages are processed on the Integration Engine in a consistent manner.

In case the message is being passed to the Sender Adapter or picked by the sender adapter, the Adapter picks the message and then the Adapter Engine passes the message to the Integration Engine. The integration engine then processes this message using a series of steps called the Pipeline services and then finally passes the message back to the Adapter Engine to send it out using the receiver adapters.
