Hi ,
Could you please follow below steps?
1. If you are showing all months of the year to user irrespective of which Month he enters. Then why do you want to give Month as input variable? Just keep year as input.
2. As other friends mentioned, create 12 RKFs with Month, Year and your KeyFigure as restrictions.
3. Hardcode the Month Values in each columns, i.e., Month = 1 for Jan, 2 for Feb, so on.
4. Create variable for Year and keep it at Filter section and restrict the same variable in all 12 columns.
5. Create a text variable(FISCALYEAR) for Year as explained by Anshu Lilhori
6. In each column heading use Jan &FISCALYEAR&, Feb &FISCALYEAR&..... Dec &FISCALYEAR&.
Hope this gives an idea!
Thanks,
Umashankar
