hi,

me is refering to the instance of class itself. The statement checks if the category is initial.

hope this helps

Hello

Me is the instance itself meaning you are "within the instance.

Therefore you could simply code:

IF ( category IS INITIAL ).  " category = instance attribute
...
ENDIF.

However, for better readability I prefer to use the ME-> style.

full spoken this would be:

if the attribute "category" of my actual instance(the one which´s method is beeing called) is initial, then do following:

initial is the initial value of that dataelement.

for a better understanding set initial = empty.
