# Return child order totals when parent total is selected

Hello Everyone,

I think I've got a P() problem that I can't seem to fight my way through.  In my data model, we have Orders, and they can contain child Orders.  This relationship is maintained in a field called "parentOrder" which contains the id of the parent order.  I have a pivot table, where I would like to show the summing data concerning an Order, as well as the summing data of it's children too.

A simple data model with parity would look like this:

```Orders:
[
orderId , parentOrder
1 ,
2 , 1
]
;

Invoices:
[
orderId , invoiceTotal
1 , 100
2 , 50
]
;

```

In my pivot table, I would have a row that would look like this

Order#    |    Invoice Sum | Child Order Invoice Sum

1              |              100      |          50

How I've embarrassed myself What I've tried:

The closest I've gotten is the following statement.

```SUM({1<[Parent Order Number] = P({\$<[Order Number]>}[Order Number])>} [Charge])
```

Here, I'm trying to say,

```Sum the charges over the Set Where the Parent Order Number is equivalent to the possible
Order Numbers in the current selection.  Because the [Order Number, Parent Order Number]
may not be in the current selection (\$) ignore what the user has selected (1)
```

This kind of works, but when I put it into a KPI component, I don't see my Sum changing with the selection changes.

Any help is greatly appreciated.

maybe something you can find from here

Concat({<orderId = p(parentOrder)>}invoiceTotal,',')

only({<orderId = p(parentOrder)>}invoiceTotal)
