Hi Zaim,
In the report variable level this is not possible.
- If you can, create one dummy object in the universe with these 3 category values as its values (object based on a derived table like select "LT 5" as category from dual
union
select "5 -10 " from dual
union
select "GT 10" from dual
)
- create new data provider with this object
- Merge the category object from both the data providers and use it in your table. so that your table always displays these categories irrespective of the measure values
