Scenario for interface between a non sap system and a SAP erp


I need some help in order to elaborate a interface between a SAP ERP and a non-sap system with the help of a XI system.

- At first regarding the interface from the non sap system and a SAP ERP :

the non sap system sends a flat file to the XI system. The flat file contains a row with header data and rows with item data. We were thinking when the file arrives to the XI system, to save the data in a header database and in a items database in XI. is it possible ?

And then to have like a job that reads the database and creates idoc and sends them to the SAP erp and updates the xi header and items database with a flag that means that the records have been sent to the SAP erp.

- Regarding the interface SAP erp to non SAP system:

the SAP erp sends idoc to XI. Then the idocs are transformed into flat file.

Is this scenario possible ?

Do we need any adaptator between the non sap system and the XI ?

Thank you for your help

Hi Bontron,

Idoc doesnot support synchronous call. So you can use either proxy or function module and inturn call the idoc from them and send response back to xi. You need to have two scenarios for your design.

Scenario1: Source File (file adapter) -- xi -- Dump into database tables (Jdbc Adapter)

Scenrio2: Pickup form Database tables (Jdbc Adapter) -- xi -- RFC Adapter ---> This is synchronous call.

Regarding the interface SAP erp to non SAP system

You can send idoc to xi and from there use File adapter to send to the receiving system.

These blogs may help you to some extent:
