ABAP - Download Code To System Using FM RS_TESTFRAME_CALL.

RS_TESTFRAME_CALL should only appear in SY-CPROG when the function module is executed for test purposes from within SE37.

If the function module is called from another program, that program name will be in SY-CPROG.

At runtime within a function module, SY-CPROG contains the name of the program that has called the function module.

This can be RS_TESTFRAME_CALL if the function module was called by hitting F8 in SE37, or it can be any other program name, depending on the program that has called the function module.
