(FAQ) As already written you have to copy in yout z-program source the code of the active enhancements as SAP will always comment those (check online help or relative notes like Note 1030740 - Copy of program with enhancement statement is incorrect)
When you copy a program that contains enhancement statements, they are deactivated in the target program.
But just copy the code not the enhancement structures, your are now in a customer program, so not needful. Of course better keep the commented enhancement in the source to reduce the task of the poor guys who will perform the next upgrade project.
