Problem amount from cash to bank


I take a amount out of my cash register and put in into my bank account.

So on the Cash I do :

Transfer money and put it into the Suspence account.

Then I get the bank account report and I choose:

Recieve money. and choose as account the suspence account.

But as soon as I do this I see this error message :smile:

This bank account contains 1 uncategorized receipts

How to solve this one ?
