A "reference server" (= SAP application server) is assigned to each profile by the CCMS profile maintenance tool. The profile is tested on this reference server. There are several reasons for this:

Many profile parameters are platform-dependent, for example the names of file directories. In heterogeneous operating system environments, it is important that the names of file directories are tested on the operating system platform on which a particular application server is going to run.

Many profile parameters are dependent on the resources allocated to their computer, such as the number and size of shared memory segments made available on the computer. Therefore, SAP shared memory pools inside the instance profiles must be adjusted for SAP pools on the host on which a particular application server should run.

The test is performed using an RFC module on the relevant application server:
