PO Matches AP Invoices

 Hello,

1) We have a PO with around 20 lines (or more). PO is approved. 

2) When we enter AP Invoice Header information and click on Match button to match the PO, all the 20 lines from PO are visible

3) As we select each line to match the PO, the field "Line Total" amount increases.

4) However, when we scroll down to see say 11th line and select the "Line Total" becomes USD 0.00. Every time we scroll to see more lines the "Line Total" becomes USD 0.00.

Can you please advice on what could be missing?
