What causes this issue?

Execute a function module via RFC could be a security issue. To prevent
misusage of tRFC calls we have established a white list check. All
function modules which are registered in SWE2 (type linkage) are part of
the white list.
Note: Type linkage settings (SWE2) are authority protected.
