iterate the values and assign to user

Question

Im trying to write a expression rule where there are two ri variables , one ri variable has type list of users and other ri variable is of type list of numbers.

something like below
ri!users: {"abc","def"}
ri!numbers: {1,2,3,4,5,6,7}

i have a use case where i should need to receive list of dictionary in below format
{
user:"abc",
number:1
},
{
user:"def",
number:2
},
{
user:"abc",
number:3
},
{
user:"def",
number:4
},
{
user:"abc",
number:5
},
{
user:"def",
number:6
}
.
.
. etc

This needs further work (extracting common rules, validations, etc.), but it should give you a good starting point:

= a!localVariables(
  local!userCount: count(ri!users),
  local!numberCount: count(ri!numbers),
  local!resultCount: max(local!userCount, local!numberCount),
  
  a!forEach(
    items: 1+enumerate(local!resultCount),
    expression: a!localVariables(
      local!userIdx: mod(fv!index, local!userCount),
      local!numberIdx: mod(fv!index, local!numberCount),
      {
        user: ri!users[if(local!userIdx=0, local!userCount, local!userIdx)],
        number: ri!numbers[if(local!numberIdx=0, local!numberCount, local!numberIdx)]
      }
    )
  )
)
