I am having trouble with a Calculated Data calculation with a Filter Expression in PI Data Link.
I have quadruple checked the filter expression - this same filter expression is being used on a separate Time Filtered query. All of my references are to AF Attributes, and the calculations work fine without the filter expression. ''\\Server\Database\TC\Compression\Station\Unit01\Driver|Speed' > 50
When I include the filter expression, I am getting the following: "There's an error in the formula you entered."
Any guidance would be appreciated.
