You can set your nominal accounts to be inactive if you don't want to delete them but you don't want to see them in drop-down list or in any Show More screens.
There are certain rules that apply to when setting a nominal account to be inactive.
Inactive record checks:
A nominal account cannot be set as inactive if it has been used:
by another account or as a Year End Update account;
in batched transactions;
on an active sales or purchase analysis record;
on a price record;
as part of the Nominal Profiler;
as a non-recoverable account on a VAT rate record;
in a recurring journal where the maximum number of postings has not yet been reached.
If any of the above criteria is not met, you will receive a validation message stating why the nominal accounts cannot be made inactive.
