Data transfer Between Two SAP Systems.

[Former Member]

Hi Experts,

I have two SAP systems and i want to connect them and carry out data transfers using ALE/IDOC. In which circumstances are a middleware (SEEBEYOND / JCAPS/ PI) is advisable and in which circumstances directly connecting the system is advisable?

Rgds,

Hi Surya,

sent to SAP for integration and processing into the R/3 core.sent from SAP to dispatch data or processing to an external non SAP system.IDOCs are used in a message based integration that is typically asynchronous.

seebeyond or jcaps Used to call BAPI/RFC.Used in Repository-Based projects.This non sap software are used to connect sap and send or receive data.

Hi Experts,

It is still not clear. So i am re-phrasing the question.

I have two SAP systems and i want to connect them and carry out data transfers using ALE/IDOC.

When exactly is a middleware (SEEBEYOND / JCAPS/ PI) is advisable for the ALE/IDOC Communication?

When is, directly connecting both the SAP systems is advisable without a middleware between them ?

Rgds,

Surya

Hi,

if you need to transform data or distribute it to external systems you should use a middleware.

If it is just IDoc from internal SAP to internal SAP you usually don't need a middleware.

But there is no general statement, I think.
