Fiscal Year change impact on BPC

Hi Experts,

My client is undergoing a fiscal year change.

From Apr-Mar fiscal year, we are adopting Jan-Dec fiscal year.

Could anyone help me with impacts on BPC with respect to:

1.) BPC Confguration changes - I believe Time dimension for Fiscal year would need a change reflecting the new fiscal year.

2.) Data impact - I believe data residing in BPC database should also be changed for correct reporting of historical data

I would appreciate your views on this.

Thanks,

Nitish
