Maintaining the RFC Connection
You may have to check and maintain the RFC connection between the BI system and the BI Accelerator landscape.

Normally you only configure the RFC connection between the BI system and the BI Accelerator once during the initial installation and configuration of the BI Accelerator landscape. This RFC connection must not be changed at any time.
You check the RFC connection using the following functions, tools, and transactions:
You can use transaction RSDDBIAMON to execute an RFC availability test to check the availability of the connection to the BI Accelerator
...
1. Start transaction RSDDBIAMON2.
2. Choose the BIA Connection Availability pushbutton.
In the BIA Action Messages screen area, a message on the status of the BI Accelerator services appears. If no connection to the BI Accelerator is available, necessary measures are initiated where appropriate. A percentage indicates how many connections are available.
...
1. Start the TREX admin tool in the SAP system with transaction TREXADMIN.
2. Navigate to the RFC Monitor tab page.
3. Choose Test Connection to test the RFC connection.
A summary of the connection is displayed. All indicators must be green.
You can maintain the RFC destination for the BI Accelerator in transaction RSCUSTA.

The RSADMINA Maintenance View screen appears. You can check the parameters of the RFC connections between the BI system and the BI Accelerator here, and change them if necessary.
You use transaction SM59 to create and maintain RFC connections in the SAP system. To check the RFC connection between BI and the BI Accelerator in transaction SM59, proceed as follows:
...
1. Start transaction SM59.
