This is the issue with displayvalue that it only searches for the first occurrence of the given value in the list and returns corresponding replacement value, dk when they will enhance it to return multiple values.

That's why we always use a generic rule to perform such operation.

index(
    local!data,
    wherecontains(42, local!data.id),
    null
  )

Although in this case it will work nevertheless, assuming that the searched value is always unique here.

Good to know. I always used index( array of CDT, wherecontains( ID I want to find, arrayofCDT . idField))

To get a single item you can just use the displayvalue function.

a!localVariables(
  local!data: {
    a!map(id: 7, name: "Max"),
    a!map(id: 42, name: "Otto"),
    a!map(id: 100, name: "Joe"),
  },
  displayvalue(
    42,
    local!data.id,
    local!data,
    null
  )
)
