No it is for an Expression.
I have tried using my If statement and it does not exlude a claim where the ACTUALGENERALSETTLEMENT = 0. Therefore it does not work.
As a similar if statement did not work for the table, I assumed this if statement did not work for the same reason when used in the chart.
The chart is a Grid Chart:
Dimension(2) - Expected Settled and Settled
Expression - as above
