Hello,

usually you should not modify the output model.

In your case I suggest to put a filter in the guard of the rule to not allow creating the
element.

Hello;
The problem is that making a filter seems to be very heavy(it takes time
to evaluate the guard and compare values) that's why i want to generate
needed elements using called rules applied to the generated model and
after to delete elements i don't need !!

Hello,

Using (unique) lazy rules, you can generate elements only if their
corresponding source elements are referred to (i.e., if you call the
lazy rule on these source elements). This means that you generally do
not end up with too many elements that need to be deleted.
