Access SAP database directly on MI 7.1

[former_member568822]

Hi,

Is that anyway to access SAP backend database directly without using bapi wrapper? If not can i treat it as 3rd party database then using https to access it.

Best regards,

Hi,

Anup is right. But there might be an option to create DB connection to a different system via transaction DBACOCKPIT and code in native SQL. I don't know wheather this is really possible, but you could try in this direction.

Hi,

The MI 7.1 is actually called NW Mobile 7.1. It has a completely architecture as compared to MI 2.5.

With 7.1, you can access the backend without using BAPI wrapper. This involves writing custom services in the flow. For more information about how to write custom service, please refer to:

Hi,

If your requirement is to access backend data without writing bapi wrappers, there are two ways:

1. Write custom service. The custom service is a function module or class method written in the DOE. And plug this custom service into the DOE runtime as described in the document. If this is still not clear let me know what exactly you did not understand from the help link so that it is easier for me to help you.

2. Write bapi wrappers in the DOE itself and configure backend destination of the adapter to point to same system (DOE).

You will have to code the logic to access the backend data, be it SAP or 3rd party. The difference between the two approaches would be that in case 1, you would have to populate the data object message (using parameter IF_MBO_READWRITE_WRAPPER) and in case 2, you would have to populate the bapi wrapper parameters.

DOE = Data Orchestration Enging, the server part of the NW Mobile.

Hello.,

If the tables you want to access in the SAP Backend System(R/3 server) is already made accessible via an existing BAPI Wrapper in the R/3 server you could achieve your objective via MI 7.0 or NW Mobile 7.1.

You have to create a Mobile application which is designed to can call these R/3 Bapi wrappers. If you do not have existing bapi wrappers and not allowed to create new BAPI wrapper in R/3 sever, the possibility of accessing those table data on a mobile client via SAP Mobile Infrastructure is not possible. (even by option 1 or 2 mentioned in the post previously).

To putt he landscape in simple terms :

Mobile Client <> MI MW 7.0 / DOE (7.1) <> R/3 server(business data / BAPI wrappers exist here)

Hope its clear.

Hi

If you want to use Smart Synchronization: Any SAP System, regardless of its release, and any SOAP-enabled third-party system. Multiple back-end systems are possible.

Dear Gan,

If you are trying to ask that "Can we access SAP-backend without using BAPI's for MI scenarios?",then

the answer for the same is NO.

As far as I know through various MI documents I have come across,If we are implementing MI then Bapi wrappers are the only way of communicating to SAP backend.

Hope this answered you question.
