The execution of the Set Up the Interface program is a one-time procedure aimed at establishing endpoints for IDocs or Web Services. When it comes to IDocs, this activity specifically caters to partner profile creation for Partner Type LS (Logical System), while for Web Services, it facilitates the creation of SOAMANAGER connectivity in the background.
In case of IDocs, you have the flexibility to execute the Set Up the Interface program multiple times for the same transaction without overwriting the existing configuration. However, it's crucial to note that when configuring outbound web services, the Logical Port setting is overwritten every time you rerun the interface settings. For outbound web services, settings are consistently overwritten if you make changes to the existing data and execute the same interface again.
However, in case of integration with SAP Ariba Buying and Invoicing, there are no IDOCs, only Web Services.
For Web Service connectivity, users are required to provide additional details, including:
- Selecting the subscribed data center
- Choosing between production or test instances
- Selecting the preferred authentication method
- Providing proxy configuration if necessary
These additional details apply to both Direct Connectivity and Mediated Connectivity, whether via SAP Integration Suite Private Tenant or methods other than SAP Process Integration (PI) or SAP NetWeaver Process Orchestration (PO).
Note
For SAP Ariba Buying and Invoicing solution there are no IDoc messages, only Web Service messages.
