In BOXI 3.1 ,we can sort the Chart Time dimensions like Cal Month ,Fiscal Period , Fiscal Week with an alerter.
We Show [Key] in chart and write an alerter [Key]=[Key] then show [Text].
But after migration to BI 4.0 , We’ll miss this functionality. We can’t able to apply alerter in chart.
I’m not seeing any fix for this except modifying the charts without alerter (it is good though)
Right Click on Chart ->Assign Data
Add [Month Text] and [Month Key] , and hide [Key]
Right Click ->Sort -> Click on [Key]
Hope this Helps.
