Hello,

I am trying to make a dynamic filter for a Report Viewer archive tablix.
Scope is to have one report and by changing value to a string, it will filter the variables needed by the name of the string. 
I have tried:
- adding online and archive sources
- i can see archived values by filtering [VARIABLE] = <variable name>
- I can see in report online string variable value by =First(Fields!STRVALUE.Value, "ONLINE1")
But I did not find a way of filtering archive tablix by the name of string variable. It does not work [VARIABLE] = First(Fields!STRVALUE.Value, "ONLINE1") .

Please let me know if you have any ideas why it does not work or if I can use a different method for this filter.

Thanks and regards,
Calin
