Can any one help on this I need a function or a logic which gives expected output from two arrays.
each variable from array1 should map with all variables in array2.
{a,b} {c,d,e} output (a,c)(a,d)(a,e)(b,c)(b,d)(b,e)
{a} {b,c,d} output (a,b)(a,c)(a,d)

Thanks

OK. Lets try this. I had to add another helper expression. This returns a true list of value pairs. I hope this is what you want.

BuildValuePair(value1(any), value2(any)):
={ri!value1, ri!value2}

HelperEx(map(any), list(any), value(any)):
=append(ri!map, apply(
rule!BuildValuePair(
value1:_,
value2:_
),
merge(
repeat(length(ri!list), ri!value),
ri!list
)
))

Call:
reduce(
rule!TS_TestExpression(
map:_,
value: _,
list: {"c", "d", "e"}
),
{},
{"a", "b"}
)
