How to create interface between SAP to legacy/thirparty?

[Former Member]

I'm going to create interface program which has to validate the fields with custom table of SAP side from Third Party System inputs and display the data with certain condition back to 3rd Party system

Suggest me which method is better &  performance also would be consider way to create interface program.

Thanks

Hi,

do I understand your chart right, that the 3rd party system is calling the SAP system?

What about developing RFC-function modules in the SAP system that are called by the 3rd party system?

No, There is SAP PI integration between SAP & Legacy system. From Legacy system they enter input based on that which has to read data in SAP serer then send back to Legacy system

You have not mentioned few details for end to end integration ...

e.g. what is communication medium for legacy (file,web service,database...?)

any way for SAP side it will be as below.

PI person will create an interface and will do a proxy class on SAP application system so yo uneed to code on that proxy class which has input/output structure as configured in PI.

your code will use input structure and give responce to output structure after processing it.

let me know if you want any other details....

Third party can be approached by SAP PI.I'm not clear on (file or web service, database) tell me the way for all..

What could be great approach either keeping text file into application server using open data set or based proxy server code, hope both of them can use open data set technique...is it? suggest is there any approach and performance should be fine.

Thanks

why you want to use file on app server ( open dataset), the way given by me will not require it.

SAP ECC will communicate with PI using ABAP proxy (based on RFC or SOAP) there you need not to do any open dataset...check the demo proxy class in your ABAP system.

It's outbound interface...How to create RFC or SOAP based ABAP proxy method. The only thing we need to communicate with third party server via SAP PI for sending data according 3rd party request based on certain conditon

just search SDN for file to proxy or file to rfc interface, you will get few very nice blogs/documents.
