Hi, Can we have the decision table data columns to contain expressions that refer to other columns, or is it just restricted to values? .For my use-case, i need to have a rule like : Condition : weight > 100 lb Action : cost = $10 (fixed) + $5 for every lb above 100. So, the data for this Action column would need to refer to the weight column's data and do the calculation : 10 + (weight - 100) * 5. Is this possible to specify this in decision table?
