DocDJ said: Shouldn't there already be a "transferred" transaction of some kind for each "A" security that has been moved?
Deleting an account permanently removes that account's records from your file. Once you delete an account, there's no way to recover the account or the information about your transactions that it contained. In addition, Quicken deletes the account name from the Category field of all transactions that have transfers to the account. These transactions appear as uncategorized transactions in reports.
In most cases, we recommend that you hide or close an account instead.
