GROUPBY error in OBIEE 10g

Question

I had a requirment where I need to calculate the duration of the etl runs on daily basis
So I have calculated the duration using the below formula.
by grouping the run_wid and using the column in criteria and hiding it(in order to avoid the error 'column in GROUPBY clause not in the projection list.')..
the reason for grouping the run_wid is when the etl fails it is run multiple times and multiple entries on same run_wid are generated so I have captured them by
grouping them based on run_wid.
Everything works here fine.
But when I want to analyze on the whole year average etl runs using the above process.
So in order to achieve this by taking the year and duration and grouping by run_wid. I again get the error 'column in GROUPBY clause not in the projection list.').
I can't use the run_wid in the criteria because it not showing at year level. Please suggest a way/idea on achieving this.

Hi Yadav,
Thanks for suggesting the idea it worked little bit by not making me to pull the run_wid in both
criteria and adding in GROUP by in advanced tab.
The problem what I am facing now is the value is not average values and its only showing the sum
of all the values
The formula for calculating Average is Avg(round(sum(TimestampDiff(SQL_TSI_SECOND,Audit."Start Time",Audit."End Time"))/60,2)/60 by run_wid)
The columns in my criteria are
Year|Average
Ex:
In year 2011 the ETL has run 50 times, I am seeing 50 etls total run time in Average.
