Hmm I think we are just near to the solution,

I have the line item like this

                             <LineItem >

                                      <LineItemID>1</LineItemID>

<ParentLineItemID>1</ParentLineItemID>

                             </LineItem>

                             <LineItem >

                                      <LineItemID>2</LineItemID>

<ParentLineItemID>1</ParentLineItemID>

                             </LineItem>

                             <LineItem >

                                      <LineItemID>2</LineItemID>

<ParentLineItemID>1</ParentLineItemID>

                             </LineItem>

                             <LineItem >

                                      <LineItemID>4</LineItemID>

<ParentLineItemID>2</ParentLineItemID>

                             </LineItem>

                             <LineItem >

                                      <LineItemID>5</LineItemID>

<ParentLineItemID>1</ParentLineItemID>

                             </LineItem>

with this data set case my rule should not raise any exception, if any
of the lineItem has ParentLineItemID = 8 it should raise an exception

Cheers

Sougata

You will need to use the exists keyword.

Without digging around for the manual you need to do something like:-

when

exists (
    LineItem( $parent: parentId )
    LineItem( id != $parent )

)
then
    // raise the exception
end

	Is 30 correct, you are not clear. Did you want one exception for
any number of violations?
