Call truncate option required for all opened calls till resolved on monthly basis

Hi,

We created a report based on total ticket count of a particular location and we have to calculate
the total SLA violated ticket in a particular location.

For every month we have
to calculate the below things

Penalty calculation
query is:

=Sum(If(Count([Ref
Num]Where([Priority Symbol] = "1"And (MonthNumberOfYear([Open
Date])=1)))=0) Then 0

ElseIf(Count([Ref
Num]Where([Priority Symbol] = "1"And (MonthNumberOfYear([Open
Date])=1)))=Count([Ref Num]Where([Sla Violation] = 0 And [Priority Symbol] =
"1"And (MonthNumberOfYear([Open Date])=1)))) Then 0 Else

Count([Ref Num]Where(
[Sla Violation] = 0 And [Priority Symbol] = "1" And (MonthNumberOfYear([Open
Date])=1)))<=(0.8*Count([Ref Num])))

if the penalty calculation is less than 80% we need to set penalty point is 1

1. Eg.

The total no of call is
10 and call closed within SLA is 5. The average % is lesser than 80 so the
penalty calculation is 1

Call truncate option required for all opened calls till resolved on monthly basis

We got JAN month unresolved calls+ FEB month total calls but we are unable to get when the JAN month unresolved calls
was resolved.

Below is the query;

=Count([Ref Num]Where([Priority Symbol] =
"1" And (MonthNumberOfYear([Open Date])=2)))+[Unresolved 1]

Unresolved 1 measure Variable.

=Count([Ref Num]Where( [Priority Symbol] =
"1" And [Status] <>"RE" And (MonthNumberOfYear([Open
Date])=1)))

Pl. help,
