First, I am using Quicken Home & Business (Canada) 2019 R15.24 on a Windows 10 desktop. I am copying and pasting transactions within the same account. I use this technique to replicate common transactions (such as dividends) because it's easier than starting from scratch each time. The security and memo information remains, I just change the date and amount. I have no problem doing this in any investment account except this one. I can copy a transaction from this account and paste it into another one with no problem, so the data is being placed in the clipboard. It's just that this account somehow blocks me from pasting - the Paste transaction command is greyed out. If I have to, I'll export and import the data into a new account but I'd rather avoid that because then I'll need to reconfigure all of the reports that use this account.Also FYI I discovered long ago that in an Investment account, a copied transaction can be pasted onto any line because this opens a pop-up entry dialogue and the result is automatically added into an empty line. In a banking or property/debt account, this same action will overwrite existing data (which I wish Quicken would protect against BTW, because it's usually inadvertent!).
Well, the story gets a bit more interesting. I exported my account transactions to a QIF file and created a replacement account but immediately found it wouldn't allow the transaction to be pasted either. I did some experimentation and found that the paste restriction is actually related to the type of transaction I'm trying to paste. I only use MiscExp transactions in this account, and that is the only type that I had been copying. It seems that other types of investment transactions do paste correctly into the account I'm having trouble with. I then found that I can't paste a MiscExp transaction into any of my RRSP or TFSA accounts, but there's no problem doing this in a non-registered investment account. This must be a constraint imposed by Quicken but I don't understand why it would be necessary. I didn't test all types of transactions, so there may be other ones that are blocked for pasting into retirement accounts.Unless Quicken is willing to change this, I guess I'll be stuck with making manual entries.
In fact, that's how I calculate the outstanding tax liability - I paste that report into an Excel template where I enter the marginal tax rate once and tally up how much I will owe. I then enter that data manually into the Tax Liability account. To avoid having to calculate incremental amounts to reach the current totals, I just reset the account balance to zero on December 31 and add the liability amounts for each investment account. The tax liability will be reflected in the TOTAL Investments value when I run a Net Worth report. If I do the report on an annual interval, the appropriate liability for earlier years is still available in the Tax Liability account. Obviously this doesn't do a good job of accounting for market fluctuations or investment changes during the year; it's just to get a rough idea of how much money is not really mine!
