Match Exception Collaboration Center: Managing Vouchers vs Line Items

We are on PUM42. We just enabled MECC in a test environment to see how it can be used to get a grip on the number of vouchers in match exception. We knew going in there are some performance issues prior to PUM45. We are working to see how we can mitigate those issues.

Our biggest concern now on usability is from the MECC Summary Page. The MECC manages match exceptions at the individual line item level within a voucher. With most of our vouchers having more than 1 line item and each line item having 3 or more Rules in match exception, it will become impossible to use the MECC to manage the issues. 3,000 Vouchers, 4 line items, and 3 match exceptions each would require managing 36,000 line entries in the MECC instead of 3,000 vouchers or 9,000 Rules,
