Round to next increment

Post some more sample data.It Is still unclear

It's perfectly clear.

The next higher whole multiple of 3 than the generated value is required.

Divide by 3, use the Ceil() function to get the next higher integer, then multiply that by 3.

(You could use round_inf, too, if you had some other conversion function that needed to be applied.)

I think you can try with ceil & mod functions .
