Push data into SAP from external system ??

[Former Member]

Hello Experts,

I am trying to do something that is totally new to me... So please help me...

Note: we are using SAP SOLMAN 7.2

Requirement: We have an external system which can push data in JSON format. SAP system should read that data and create some documents in SAP. I have breakthrough in JSON parsing and creation of documents in SAP. But the main show-stopper is connection between in the external system and SAP.
Problem: I was wondering to use Web Services of SAP and call this web service from external system. So I have created the webservice through an RFC function module which has my logic. But when I test this webservice internally from SAP system it does not execute the lines of code. Also external system fails to execute codes in this webservice handler fucntion module.

As part of testing, I also tried to use SoapUI software to test if my SAP webservice can be reached from external system. I configured a new SOAP Project in SoapUI and gave the WSDL link that I got from SOAMANAGER. It can read to our SAP system web service, but unable to execute the logic in the RFC function module.

Is there anything I am missing. or any guidelines relating to this.

Thanks in advance.

Regards,
