Multi-page OCR & Pattern Matcching

I have an invoice that includes information on the front and back side. During Page Processing, I have two Zone OCRs, one for each side (see pic). Each time I try to scan the invoice, it only captures from the front side OCR. Nothing in the event log even shows up for the back page, and obviously the pattern matching requiring the back page OCR fails. I've tested with the paper source set to Automatic and Duplex, but it doesn't seem to make a difference.

How would I be able to pattern match the OCRs from both the front and back pages of each invoice?

I should note that I'm currently testing by running Test processes on the Pattern Matching process.

Did you make any changes to the session since the screenshot in your original post? Your processing pane does not seem to show any document identification. At this point, it might be faster to have your reseller open up a support case and attach the session and sample images.

How is your "Back Page" process set up? Is it running on all pages? What are the settings in your pattern matching process?

This configuration works for me. Where is the token for the second page (your screenshot only shows tokens off the %(dateZone))?

What do you see in the Processing Information Pane (F5 to open it if not already opened) when the 2 pages are processed?

The Back Page OCR runs only on page 2 and I changed the sample page of the OCR to page 2 in order to select the correct zone on the page. The Pattern Matching process runs on page 1 and 2. See attached pics.

The Tax and Subtotal tokens are taken from the back page OCR. See pic1. I've attached both the Processing Information Pane and the Output log.

That must have been from a test process, which I now understand only runs on the current sample page. I ended up having the classification recreated from scratch, and after a few issues with the last page identification, it looks like it's working! The setup is, as far as I can tell, almost identical to the first attempt though. There may have been some confusion as I was testing different setups using the test processes function rather than actually running the test invoices through.

Thanks for the assistance!
