We close the gl every month but have not closed AP and AR for a few months. Someone else used to do this. It would be my first time. However I read that when I do this payment details will be deleted and zero balance invoices will be deleted. This is not acceptable. We offset AP and AR and end up with 0 balance invoices which we need to have details on. I have wondered why I have so much trouble getting to payment details. Why does it do this? Do we need to do this? What will happen if we never close AP and AR, only GL? We are on MAS90. Our year end is very near and I need a better understanding. I am fairly new to MAS90.
