You will need to create an OData Service for the transaction, table, etc. that you are trying to access. This service needs to be published on a SAP NetWeaver Gateway, and can then be consumed in a Mendix app, as you described. I’m not an expert on creating OData services in SAP, but you can try following this guide: https://blogs.sap.com/2016/05/31/odata-service-development-with-sap-gateway-code-based-service-development/
Also, make sure that any OData service you create is not OData v4. This version is supported by SAP, and recommended in certain documentations, but is not yet supported by the SAP OData Connector module. The guide above helps you create an OData v2 service.
You can find a very straightforward tutorial here: https://docs.mendix.com/howto/sap/use-sap-odata-connector
Took me less then 5 minutes to get SAP data into Mendix. Its a great starting point for everything else
Thank you so much for your quick reply!
I understand that i must set SAP Gateway to connect Mendix App.
And please tell me if you know ,
is there another way to connect SAP ERP 6.0 and Mendix App?
I want to connect 2 applications as possible as simple.
Sorry for bothering you.
Thank you for your comment.
I noticed that i must prepare to connect,
both SAP NetWeaver Gateway and Mendix Odata connector!
i will try.
