Changing of Calendar year into Fiscal year in WEBI report

Hello Experts,

I am using SAP BO 4.0, Back end data is HANA.

Now i have to create one webi report on HANA.

I am getting the data from HANA in the format of calendar year(i.e,. Jan-2015,Feb-2015......Dec-2015)

Now i have to convert the calendar year data into Fiscal year data.(i.e., Apr-2015,May-2015......Dec-2015,Jan-2016,Feb-2016&Mar-2016).

I am Getting the objects "MONTH" & "YEAR" from HANA.

Can anybody please suggest me that how can i do???
