I'm using the following expression to pull a default date from yesterday:
=DateAdd("d",-1,Today())
The business requirements changed and now they want to see yesterday AND today. Is it possible to add onto this expression to include yesterday and today?
Just set the parameter to yesterday date and change this in your query.
WHERE [DateColumn] >= @DataParam
If you want to show the dates the report is using, try this in a textbox:
="Dates: " & Parameters!DateParam.Value & "-" Today()
UPDATE: If your parameter is multivalued you have to add two default values using these expression:
=Today()
=Today.AddDays(-1)
Then in your query change this:
WHERE [DateColumn] IN (@DateParam)
Let me know if this helps.
