Hi,
Create a report and Group By Assigned Type.
Select Group Header right click select section expert then in Supress (No DrillDown) Click the formula button and enter
<Static Parameter>='NO' and <Dynamic Parameter> = '...All'
Create 2 parameters
1)Static Parameter with Yes and No Values
2)Dynamic Parameter with Assigned Type
IN Group Selection Formula Enter
IF <Dynamic Parameter>='...ALL' Then
true
else
{table.AssignedType=<Dynamic Parameter>
So when you run the report user will be given two prompts to select from if the user selects Yes and All then the report will show all the records with Group Assigned Type.
If the User Selects No and All then no groups will be displayed.
If user selects Yes and Assigned Type the it will display the Group and Details for the Assigned Type Selected.
Hope that solves your problem.
Thanks
Rahul
