Because formula are different for Different Scenario

I need to make it dinamic so that based on the Scenario Formula should be Take and Calculated.

SCENARIO - TGT_PAYMENT_TYPE - PAYMENT_FORMULA

NORMAL - SAL - SAL-ADV

NORMAL - COMM - ALL_1+ALL_2-ALL_3

NORMAL - BONUS - SAL * 1.1

MONTH - SAL - SAL

MONTH - COMM - ALL_1+ALL_2

YEARLY - BONUS - SAL+ALL_1+ALL_2
