Hello Amit,
If your requirement is like what Amit Kumar mentioned the please go ahead with his approach. But, if you are looking to hide entire duplicate row e.g.
Closed Permanently Resolved Service Desk-General No since this has multiple entries then please refer to steps below.
I tested the results on below table and will eleminate ID=2 since its an duplicate.
Create 4 variables on your report.
| ID | Name | Dept | Sal |
| 1 | ABC | CA | 1000 |
| 2 | ABC | CA | 1000 |
| 3 | ABC | CA | 2000 |
| 4 | ABC | FI | 5000 |
| 5 | DEF | FI | 5000 |
Variable1(Dimension) =[Name]+[Dept]+[Sal]
Variable2(Measure)=RunningCount(NoFilter([Variable1]);([Variable1]))
Variable3(Measure)=Max(NoFilter([Variable2])) In ([Variable1])
Variable4(Dimension)=(([Variable2]=[Variable3]) And ([Variable3]<>1))
Now pull the Variable 3 in your block and apply filter to the block saying [Variable4]=0. Then just hide the dimension [Variable4].
This will eliminate your duplicates from the block. Hope this helps I used this logic in an opposite manner where I had to just show the duplicate values.
You probably may have to replace [Name], [Dept] and [Sal] by the columns that you want to consider as duplicates.
Thanks
