How to AND/OR conditions in SAP HANA Graphical Modeling in Calculated Columns in Calculation Views?

Hi,

My requirement is i need to calculate YTD and MTD for Breakdown Duration Technical Object wise of an Equipment for a Fiscal Year and for the given input date.

If suppose Input Date is "20/02/2015" then my Fiscal Year Start Date will be "01/04/2014" and Month First Date for the given date is 01/02/2015.

Here i'm getting the below errors.

1. Using a Calculated Column in Other Calculated Column.

2. not able to use AND/OR Conditions.

Can anyone suggest me how to use AND/OR conditions when using different conditions like below.

Please suggest me how to solve this and also suggest me what could be best approach to calculate MTD & YTD calculations i.e. Graphical or SQL Script approach and how to proceed.

Thanks in Advance.

Ramana.
