SSRS Month over Month Date Expression beginning with Previous business day

The business requirement is to have a report with a month over month date starting with the previous business day. How do I achieve?

For month over month - my expression is:

=dateadd("m",-3,Today)

For previous business day - my expression is:

=DateAdd(DateInterval.Day
, Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
    ,DatePart(DateInterval.WeekDay, Today()) = 1, -2
    ,True, -1)
, Today())

How can I combine these into one expression so that the month over month starts with the previous business business day and not today's date?

Thanks,

You can use your previous business day expression in the start business day expression:

=dateadd("m",-3,
DateAdd(DateInterval.Day
, Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
    ,DatePart(DateInterval.WeekDay, Today()) = 1, -2
    ,True, -1)
, Today())
)

However the outer DATEADD function could produce a date which is not business day and your query will return rows from that date, if your datasource doesn't match dates in non-business days that is not a problem, the problem comes when you have non-business dates and you don't want to report it.

For simplicity I'd create a Hidden parameter (check the Hidden property radio control in Parameter properties) called ThreeMonthsPreviousDay, set it to Date/Time data type and use the the below expression in the Default Values property.

=DateAdd(DateInterval.Month,-3,
DateAdd(DateInterval.Day
, Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
    ,DatePart(DateInterval.WeekDay, Today()) = 1, -2
    ,True, -1)
, Today())
)

Now you can get the Business Date 3 months before the previous business day so use:

=DateAdd(DateInterval.Day,
  Switch(
    DatePart(DateInterval.WeekDay, Parameters!ThreeMonthsPreviousDay.Value) = 2, -3,
    DatePart(DateInterval.WeekDay, Parameters!ThreeMonthsPreviousDay.Value) = 1, -2,
    True, 0), 
 Parameters!ThreeMonthsPreviousDay.Value)

Let me know if this helps.
