I recently helped a customer clean up their cca asset accounts in the chart of accounts
It was a bit of a mess...They were able to add subaccounts to the 1800 classes, and because they put opening balances in we couldn't delete them after. The customer did not know that capital assets are to be added on the left under ,ore > capital assets.
I was able to clean everything up. I added new accounts, re linked the cca accounts correctly, and for the other accounts I had to renumber them to the bottom of the asset list. Because there were balances we were not able to hide them.
Not the biggest deal in the world but her books will be forever a bit of a mess. It could have been prevented by simply disabling users from adding subaccounts to the cca or other mandatory accounts.
