Setting the RFC Destination 

Use

Before two or more systems can communicate with each other, the technical coupling between them must be set up. The target address for the data transfer is determined during the setup of an RFC destination in R/3. The name of the corresponding RFC destination must be identical to the name of the logical target system (APO). One RFC destination is required for each target client (for example, 001).

Prerequisites

System Administration needs to have made the necessary system settings in the distribution model (ALE).

See Checklist for Setting Up the System Infrastructure
