Cant increase Transaction Fee as got new incoming transaction on my wallet

[AlexGrovMer]

Hello everyone!
Need your help

I set the lowest transaction  fee 
It is in process for about 24h
During this time I got new incoming transaction

Now I want to increase fee for my outgoing transaction but got error "Conflicts with transactions history"
I suppose I have to join them somehow? But Don't know what to paste in "row-transaction" field

Or how to resolve this conflict and rise fee?

For rising the fee you right-click the unconfirmed transaction, rise the fee, sign and broadcast.

But I am not convinced that it will use funds the new incoming transaction, I think that it will use same input(s) and make one of the original outputs a bit smaller.
Edit: it looks like I was wrong about the RBF strategy, it's described correctly a bit further down.

Yes! You are absolutely right!!

Electrum allows you to add new inputs for bumping the transaction fee.
You can do so, even if the new inputs come from a transaction made later than the original transaction.

Also, you can click on "Show advanced setting" when bumping the fee and select the strategy.



If you use the first option, there would be three cases:

1. If there's a change (which is sufficient) in the original transaction, electrum decrease the change.
2. If there is no change (or there's a change, but it's not sufficient) and there's another available UTXO in the wallet, electrum combines that UTXO with original input(s).
3. If there is no change (or there's a change, but it's not sufficient) and there is no other UTXO in the wallet, there is no option other than decreasing the payment amount.

For the record, this only happens when you clicked "save" instead of "broadcast" when increasing the fee through rbf.

Reason is simple: the low-fee transaction is already in your history and the replacement that you want to save locally has the same inputs and outputs so it can't be saved.
