Sage 100

We are on Sage 100 (Version 6.00.3.0). We have noticed, only in the last week, that we have invoices dropping line items when we switch from Lines tab to Totals tab and go to print. I am not 100% sure of this, but it seems it is just the last item…

Once every 1-2 weeks I rebuild all sort files and am wondering if I should also be rebuilding the key files? Is there any risk/downside to rebuilding the key files? Also, when I am running the utility do I want Integrity Check and Optimize File checked…
