ORDCHG - Delete a Line Item

Hello,

  I am using ORDERS05/ORDCHG for  our Inbound EDI 860.   I am able to change my PO with a New Price and no of units..

However, I am unable to delete  a line item from the existing sales order..

Say suppose my initial sales order has 3 line items.. My vendor sends PO change for 2 items and vendor wants to cancel the third line item...

Was wondering if the FM - " IDOC_INPUT_ORDCHG " supports the Deletion of line item..

Have anyone has faced this issue..

Thanks..
