Previously deleted old invoice due to an error and how to input it again?

SUGGESTED

Hello,

I have some issues with Sage 50, and long story short, I think I need to input provously deleted invoice due to an error.

In May 2020 Sage came up with an error for 2 invoices back from 2014 and 2016. I have managed to delete those and Sage was fine with it then.

Again, long story short, no one in the office was aware we had to clear audit trail (I think the previous accountant was doing that but they left before I started in 2013, so up until now when I started my accountancy courses I had no idea about it).

Obviously, it got to the point where we can't use Sage without it crashing multiple times a day.

I was in touch with Sage and followed all the steps with regards to clearing audit trail, but it looks like there is a corruption at some point, as I can't clear audit after 2015. I was advised to try year after year (rather then jump straight to year 2020 or 2021), and if that didn't help I was advised to send it to Sage for them to fix it.

And then last night I remembered the invoice situation from 2 years ago. I imagine Sage can't delete data as some of the figures dont match anymore, because I deleted those invoices back in 2020. Is there any way I could input them again, without upsetting current years? Or  should I just send it off?

Thank you in advance,

Agata
