Dynamics GP 2013 create Enter/Match Invoice, pop up error message "4852 Stored Procedure= taPopEnterMatchInvLine Error Description = Shipment Line Item does not exist to match Invoice against"

I have created a Purchase Order in GP, and created a PO Receiving Transaction for this PO. After that I use the e-Connect POPEnterMatchInvoiceType to create the Enter/Match Invoice. but e-Connect pops up error message "4852  Stored Procedure= taPopEnterMatchInvLine  Error Description = Shipment Line Item does not exist to match Invoice against". The Xml file as below.

PO Number:PO2085,  the PO Receiving No. is RCT1163.  I checked the PO Receiving thru Receiving Transaction Entry and SQL table POP10500, the Receiving Data is correctly.
