#Sail, i have 2 different array, i want to convert both array as columns in to a

Create a rule to define adhoc data structure like.
{value1: ri!val1 , value2: ri!val2}

After that, use apply function from main rule to create your combined data structure of two arrays.
Then pass the resultant structure inside todatasubset function.

You can achieve this by creating a local cdt variable and defining the 2 columns as 2 arrays like local!cdt:{col1:local!array1,col2:array2}.
Further u can convert that into datasubset using pagingInfo.
