Can you please explain more clearly about the scenario and try this outstanding feature next time you paste your code to make it more readable and sensible. 
 AFAIU, what you want to achieve here can be done using the below sample code: 
 a!localVariables(
 local!a: { "A", "B", "C" },
 local!b: { "X", "Y", "Z" },
 a!forEach(
 items: local!b,
 expression: a!localVariables(
 local!index: fv!index,
 a!forEach(
 items: local!a,
 expression: rule!getTestData(input1: ri!employee, input2: fv!item)[local!index]
 )
 )
