I think the enhancements are separate objects which are merged at runtime. if you want to define a variable which should be visible in the whole program (so also in other enhancements and possible user exits) then a declaration is needed.

The declaration will merge with the top include of the program.

If you use the code part to declare a variable it will only be visible In the enhancement where it has been defined and maybe in the same process block.

That's why I think you need to use declaration for declaring variables in an enhancement.

Please correct me if I am wrong
