Ways to send data between SAP and non-SAP system


I am having a requirement related to India GST in which I would need to send the details like invoice and other required details for GSTR forms from my SAP system to the GST-ASP (which is a non-SAP system). I am not from ABAP or BASIS so I am not aware of various alternatives available for my requirement. At this moment, I came to know about 3 ways -

1. Opening SAP to 3rd party tool to fetch and send the data - What are the various ways through which we can provide access for the 3rd party tool to SAP, and which is the best one?

2. Placing the files on a shared folder from where both the parties can access it - What would be this shared folder? And how can we achieve this?

3. Manual upload from SAP to ASP - We don't want this method obviously, unless as a last resort in the worst case.

Any help on various alternatives and the pros n cons would be appreciated.

P.S: I have already searched over the community for my requirement. Though I got a vague idea on the available alternatives like (PI, FTP etc) I still dont have a solid idea.

    Hello Ady,

    A good starting point for any SAP integration considerations is

    Integration Solution Advisor Methodology (ISA-M)

    The strategic SAP integration platform are the SAP Cloud Platform Integration Services. However, if your integration scenario is from on premise to on premise, I would still consider SAP Process Orchestration (PO).

    Best regards

    Hi Ady,

    Generally the data between the SAP and NON-SAP system can be done using the following ways

    1. Using RFC(Remote Function call).. where the required data that need to be collected in the function module and then this function module is called in the Non-SAP system

    2. Using the BAPI also u can a pass the data.

    3. Web-service : Design a web-service in the ABAP and call this web service in the your ASP system mentioned. This can pass through the Pi/XI if the infrastructure is available at the service provider.
