Need process to RTV on a PO when no receipts have been made.

Company 1 purchases Item A from Supplier A

Supplier A dropships Item A to Supplier B

Supplier B uses Item A to create Item B

Company 1 purchases Item B from Supplier B which includes the cost of Item A in the price of Item B

Company 1 needs to debit the accounts payable from Supplier B for the value of the raw

material (Item A) supplied by Supplier A.

Company 1 would like to use a PO RTV transaction or other Purchasing return transaction to remove the raw
material from Greatbatch's inventory and debit the second suppliers accounts payable.

Does this make sense?  And does anyone have any ideas of how to do it?
