VI import for PO Receipt of Invoice

Hello,

I have created a VI job to import into PO Receipt of Invoice and encountered a problem with assigning the OrderLineKey from the original purchase order. I have it working if I manually provide the order line key in the import file but need to assign it automatically.  

Has anyone else encountered this and developed a solution they are willing to share?  One thought is using perform logic to read the line key from the original purchase order using the PO number and item code; however, I have limited knowledge of writing perform logic.

Thanks
