Hi,
When all the procurement process is finished, it must be possible to
delete the PO item for archiving purpose for example.
If however you try to delete the item after GR but before invoice
receipt, the procurement process is not complete, therefore the error
06115
( Quantity delivered differs from qty. invoiced (Function not possible)
Also note the item shall be marked as deleted, but not actually
removed from the system, it shall still be available for reporting.
I hope this explains why the system allows you to delete a PO when it
has a GR and IR completed.
Please refer to the online documentation changing and cancelling
Purchase orders which states as follows :
"An item order may be only deleted if it is closed. Items are regarded
as closed if one of the folowing criteria is satisfied :
- the ordered quantity or more has been delivered and invoiced.
- the delivery completed has been set and the invoiced quantity is
  greater or equal than the quantity ordered.
- no follow-on processes (such as reservations) relating to the item are
  active in the system."
->  This means that the delivered quantity of the goods must agree with
    the invoiced quantity."
About Archiving, please ensure that the following criteria must be ful-
filled in the SAP R/3 Standard :
Checks for purchase orders and scheduling agreements:
o  If the GR indicator has been set, either the Delivery completed
   indicator must have been set for the item (for service items this
   is essential), or the GR quantity must be at least as large as the
   quantit ordered less any underdelivery tolerance. If the IR
   indicator has also been set, the IR quantity must equal the GR
   quantity. In this case, the final invoice indicator is irrelevant.
o  If the GR indicator has not be set but the IR indicator has, then
   either the final invoice indicator must be set or the IR quantity
   must be greater than or equal to the quantity ordered.
o  There must not be any #GR blocked stock# in existence.
o  There must not be any open down payments.
o  In the case of stock transfers (irrespective of whether within a
   company code or across company codes), the GR quantity must be
   equal to the GI quantity. If the stock transfer was carried out
   using an SD delivery, the GR quantity must also equal the outward
   delivered quantity.
o  The delivery costs must have been cleared.
o  If the Check info record indicator has been set in Customizing for
   the document type/item category combination, the item must not
   appear as the last document item in the info record (if one
   exists).
o  No parked invoices may exist.
o  If the item results from a sales order (EKPO-STATU = #V#), the
   overall processing status of the sales order must be either SPACE
   (not relevant) or #C# (completely processed).
o  The posting date of the last PO history transaction/event
   (e.g. goods receipt or invoice for delivery costs) must be as far
   back the past as specified in residence time 1.
If these criteria are not fulfilled, the documents cannot be archived.

I hope this can be of help
