Adapter Connections
The adapter use connections to communicate with the SAP system. You have to configure the connections if required to ensure the effective and correct communication.
Reconnecting to the SAP System
For outbound connections, the adapter automatically tries to connect to the SAP Gateway service if any connection errors occur. If connectivity is not re-established within the maximum interval configured in the project, the corresponding server connection pool can be suspended and the adapter will be stopped if needed. See Server Connection Pool Configuration Reference for configuration details.
For inbound connections, the adapter automatically tries to connect to the SAP system if any connection errors occur. If connection is not re-established within the maximum number of attempts configured in the project, the corresponding client connection pool can be suspended and the adapter will be stopped if needed. See Client Connection Pool Configuration Reference for configuration details.
Connecting to Multiple Client Connection Pools
When configuring an inbound adapter service, adapter services reference the same client connection pool by default; however, this can be changed if needed.
- Adapter service requires specific user credentials.
For example, the service is creating financial documents in the SAP system and requires a specific user id when the documents are created.
- Adapter service is using a client connection pool based on Logon Groups and requires a specific group.
For example, the SAP system maintains several Logon Groups and one of those groups is required for processing.
- If the SAP schemas are the same across the SAP system then the adapter service is using a client connection pool referencing a different SAP system.
