Purpose
CIS mobile uses an RFC connection to enable access to SAP data. This serves as the foundation for communication between CIS mobile and the SAP system to display or save data.
Login and User Configuration
  • Individual Login: Users log in to the mobile application with their SAP user account and password. The login is authenticated with the SAP system.
  • General RFC User: It is also possible to use a general RFC user for all logins. However, this is uncommon and requires additional security measures.
What is RFC?
RFC (Remote Function Call) is an SAP proprietary protocol that allows functions in the SAP system to be called remotely. It serves as an interface for data exchange between external systems and SAP.
Configuring the RFC Connection
  • An RFC destination must be set up in the SAP system (transaction SM59).
  • Connection details such as hostname, system number, client, and optionally an SAP router string must be correctly specified.
  • These details are entered in the S10 repository, where the connection can be tested.
Security and Permissions
  • An automatically generated server ID can be specified in the SAP authorization object to restrict access to authorized servers only.
  • SAP users require specific permissions for the RFC connection and the data objects being accessed.
Troubleshooting
  • Connection Issues: Check the RFC destination in SM59 and the connection settings in the S10 repository.
  • Authorization Issues: Ensure that the user has the necessary SAP permissions.
