Aggregation in web studio
If there is a use of aggregation function on multiple groups,
like shown below for exception report which has 3 groups (Employee Id, Employee Name and Exception type) and aggregation is applied on Exception Hours, the aggregation value is visible 3 times (as highlighted).
The number of times the aggregation value is visible is equal to the number of group by applied.
Birt web studio does not provide any control to hide/remove the multiple aggregation values.
