1.1. How can I find out my current qrfc version and supplement?
You can find out your current version and supplement number using any qrfc transaction (such as smqs, smqr, smq1, smq2), under information-> version. if only the qrfc version is displayed (that is, without a supplement number), this means that you still have a supplement lower than 7.
2. What is the latest qrfc version and supplement?
See the sap note 438015. Please, note that supplements are only relevant for the latest version of qrfc. In other words before installing any supplement you must have the latest qrfc version already installed.
In addition to the current support package, the RFC Library (librfc) version for external programs, Kernel Patch Level and qrfc version with their supplements are also important. note 545784 lists the relevant secondary details for the current versions.
