I have concatenated two tables with a flag called Model.
Model = Current Activity and ABF Activity
I have added this as a dimension to the layout, this works great.
Now what i want to do is add a column that calculates the difference between the two.
any ideas please
The easier way to do it
1) Add the first expression Model = Current Activity
2) Second Exporession will be Model = ABF Activity
3) Column(1) - Column(2).
I hope its clear.
