list of dictionary in forEach

a!localVariables(
  local!data: { date(2023, 10, 10), date(2024, 10, 10) },
  local!country: { "ITALY", "USA" },
  a!flatten(
    a!forEach(
      items: local!data,
      expression: a!forEach(
        local!country,
        {
          DATA: local!data[fv!index],
          COUNTRY: fv!item
        }
      )
    )
  )
)

Ganesh's answer above gets close but doesn't give the correct distribution of dates to countries (it just repeats the same two).

Here's my solution, which stores a reference to the current item in the outer forEach loop for reference in the inner loop (otherwise it's difficult since the loop-specific scope variables in the inner loop refer ONLY to that loop).  We still of course need to call a!flatten() on the final generated list.

a!localVariables(
  local!dates: {date(2023,10,10), date(2024,10,10)},
  local!country: {"ITALY", "USA"},
  
  local!firstList: a!forEach(
    items: local!dates,
    expression: a!localVariables(
      
      local!currentDate: fv!item, /* we need to manually store a reference to the current outer loop item when we try to access it from the inner loop */
    
      a!forEach(
        local!country,
        {
          DATE: local!currentDate,
          COUNTRY: fv!item
        }
      )
    )
  ),
  
  a!flatten(local!firstList)
)

fyi:

thanks

Amazing! thank you so much
