Hi 

Sorry for the late reply, Sage 50 CA only allows you enter transactions in current and last fiscal year dates.

You can check by going to "Setup, Settings, Company, Information", if the 2020 is historical year, then your options are limited.

1. Go to backup before advance to 2022, re-enter data.

2. Make corrections in earliest date available.

You can contact Customer support if you require any further assistance. 

Hope this helps.

Thank you for replying to my question.

I couldn't go back to 2020. It can only allow to change 2021 and 2022.only 2 years.

I wish Simply accounting have more years that we can change, at least 3 years. 

So, our accountant will make some adjustment. 

Again, thank you for your reply.
