Hi Silva,
Not sure if i understood your question - but will try to add in my comments.
In this report the form uses a variable, this variable uses the current year and gets the data from RPSCO and consolidates the values for that year.
all the previous year values from the current year are consolidated under row 'Previous Years'
Current year value is under '$0FY' here the output on the report is updated with the year as shown in your example 2014 Plan
following years are calculated as '$0FY+1', '$0FY+2' etc in future
so if you change the columns PLAN, ACTUAL, VARIANCE and VAR% to other language, the year number is added to these columns.
Question is do you want to change the number also to the other language - if not i think you should be good.
