Reference set as branch

To excess a list of all losses of the order lines combined I wish to create a reference set within a group.

'Orders': collection ['id'] {
  ...
  'Order Lines': collection ['id'] {
    ...
    'Losses': collection ['id'] {
      ...
    }
  }

  'Losses': group @breakout {
    'Test': reference-set -> ^ .'Order Lines'* .'Losses'* = branch ' '
  }
}

The code I created however, does not work. Can anybody help me to visualize all losses in one collection?

Do the id’s of the Losses refer to a specific type of loss, like this:

'Losses': collection ['id'] {
  'id': text -> ^ ^ ^ .'Loss Types'[]
}

In that case you can use union:

'Losses for Order': collection ['id'] = union (
  '' = .'Order Lines'* .'Losses'* >'id'
) {
  'id': text -> ^ ^ .'Loss Types'[] = key
  'Order Line Losses': reference-set -> ^ .'Order Lines'* .'Losses'* = branch ''
  'Occurences of Loss Type': number 'items' = count <'Order Line Losses'*
}

If you just want to show the Losses on the level of an Orders item, I recommend adding the @small annotation to the Order Lines and the Losses.
