I have issue with a parameter in CR XI R2 ver.
Report has several fields and several parameters.
One of Parameter is used against a field that could have next values:
Three quarter full,
One quarter full.
Problem is that this field could have value Null and it could be empty too.
Case is more complicated as user wants to show particular record even if this field do not have value it means if record for this field has value Null or is empty and show on report as Unknown.
It means that Unknown actually covers three values first sting: Unknown ,second: Null and thired empty string.
Any Idea how to do this?
