If you have a Dashboard sheet and you want to list all the unmatched transfers, you can use a formula like this:
=FILTER(Transactions!A1:I,Transactions!O1:O="Transfer",Transactions!H1:H<>"match")
In this example, the first range, Transactions!A1:I is the full range of the Transactions sheet you want to display. In my example, it goes to column I but you could make that any column.
The next part tests if the Transaction is a Transfer Type. (Unlike @jpfieber system, I use the Transfer category, but you could write a formula for filtering out “Transfer In” and “Transfer Out” categories.) In my Transactions sheet, column H is an auto lookup of the Transfer Type based on the Category of the Transaction in each row.
This post explains how to get a Group column in your Transactions List.
Groups in transactions list
Use the same concept to make a Type column.
The last test filters out the Tags that say “match”. In my case, that’s column H. If you have multiple tags, in addition to the word match, this system won’t work.
With those filters, only unmatched transfer transactions will appear.
