Testing or executing a function module without having access to SE37

ISSUE: In certain environments you may be restricted from using SE37 to execute or test a function module. There is a way around it if you have access to SE38 or SA38.
SOLUTION: Simply use SE38 or SA38 to execute program RSFUNCTIONBUILDER. This brings up a very similar screen to SE37 as shown below, where you can then proceed to test out your function module
