Alias in Disocverer report

Question

Is it possible in discoverer to use one folder(Table) multiple times in one report.
For ex: same table with different where clause...like
1. current year
2. Last year
3. next year..
Or we need to create 3 folders with same table in administrator.

Hi Muralidar
The suggestion given by Jayu will get you exactly what you want and I would ask you to try it out.
Jayu - this is fine so long as the ORDER BY clause refers to a date. Therefore, the user might want to make sure that the variable called year is actually a date and not a string. As you are probably aware, when the RANGE INTERVAL is YEAR the ORDER BY must use a date.
Therefore, in the case when year is not currently a date, you might consider this (I've highlighted in bold the code I am suggesting):
for Previous year,
SUM(Amount) OVER(PARTITION BY proj_id ORDER BY TO_DATE("year", 'YYYY') RANGE BETWEEN INTERVAL '1' YEAR PRECEDING AND INTERVAL '1' YEAR PRECEDING )
next year,
SUM(Amount) OVER(PARTITION BY proj_id ORDER BY TO_DATE("year", 'YYYY') RANGE BETWEEN INTERVAL '1' YEAR FOLLOWING AND INTERVAL '1' YEAR FOLLOWING )
