IntervalMatch() like in Expression

[#1]

Dear Team,

I have a requirement that in sum of Expression i have to define some Category from A to G

for example :

if SUM of Turnover is more that 20% from Prev SUM of Turnover its get Category A, if greater than 10% then B and so on.

So is there is any function like IntervalMatch() which we do on Load.

Regards,

JKV
