Exceptions on Receipt Accounting infolet

We are trying to looking at the exceptions on the Receipt Accounting Infolet but i am not able to click on the count to see the exception details.

For ex

Request id Bill to business unit Exception Source Exceptions

XX XX Purchase Order 5

YY XY Accounts Payable 1

If i view by error type, only for the second line it shows the following error: Missing value in invoice which is matched to receipt for line 2 but i don't see anything for line 1. What is stuck against 5 purchase orders?

How do we clear these exceptions? Please advise.

Thanks,

Arthi
