How can we interpret when we choose Value Change Policy as each use and order as random?

Hi,

Suppose we have our variables in one table where three columns (a1,a2,a3) are there. and we want to change the variable's value on each use and in random order. And also value from each column should come from the same row at each use.

means if value is getting picked from row no 2 for cloumn a1 then value should come from same row no for column a2 and a3 as well.

Can we achieve this?

Thanks,
Abhishek
