Account, Date Closed; not being nulled when Status changes from Declined/ Unwanted to Quote

The Account's "Date Closed" was NOT being nulled when it's status changed from Declined/ Unwanted to Quote.

This meant some functions treated the Account as Closed, when in fact it is Open. For example, the Account Trial Balance Reports excludes these Accounts when a Date As At is entered.

To recreate:

1. Open an Account as a Quote.
2. Set to Unwanted (but not immediately Archive on the Account Type).
3. Reset to Quote.
4. Open the Account.

Note, the database update nulls DateClosed for Quote and Open Accounts.
