What is difference between Adapter and Proxy

[Former Member]

Hi All,

Can any one tell me what is the difference between

adapter and Proxy(ABAP or Java)? When we want to use

Adapters and when we want to use Proxies.

Suppose I have one scenario like File to Idoc. Then

which one i want to choose.

thanx and regards,

Mukharji.

Mukharji,

Apart from the answers by others, one interesting fact is to Connect to a Proxy(Java or ABAP), you need XI type of adapter.

Hi Mukharji,

You only require an adapter to communicate with SAP systems older than Release WAS 6.20 and with external systems..

And Proxies

You can only use the Proxies for systems that are based on SAP Web AS 6.40 or higher..

Hi Mukharji,

<u>Proxies:</u> are interfaces which will get executed in the application system. They can be created only in the system from message interfaces using the proxy generation functions.

<u>IDocs/BAPIs/RFCs/Interfaces from external systems</u>:-

Here, you can connect all interfaces that are already available in the system to the Integration Engine by using adapters. The adapters map between the XI message

protocol and the relevant interface type.

If the adapters do not call an interface (for example, if the message data originates from a database or file), you must configure an interface yourself.

Go through this documentation for further details:-

Hope this helps!

Hi Mukhariji,

>>Can any one tell me what is the difference between

>>When we want to use

You can use proxies for systems with WAS >=6.20

>>Suppose I have one scenario like File to Idoc. Then

If you already have a standard idoc for your scenario then you can use idoc adapter to reduce development efforts.

If it is a new functionality and your target system has WAS >=6.20 then you can use proxies.
