Moving your old/inactive accounts from current reports to an old old/inactive report is a good way of organizing the NV1 books for presentation for printing in NV1. However, moving these accounts does not mean they do not need to be ATYPE’d for NV2. These accounts must be ATYPE’d so they come in properly in NV2 under NewViews > Account > Account types. I suggest that you review the NV2 Demo books to see a clearer picture of what I mean.
Setting up an Old Accounts Receivable Report etc does make things clearer in NV1 as well in NV2 as the report setups in NV1 will come over to NV2 after the NV1 Import has been performed.
