# Blocklist Customer Data from Transaction list

Within the Transaction list a User has the opportunity to add Customer Data with one click to the Blocklist.

In order to do that, just follow these Steps:

Select the Transaction you want to take the customer data from and scroll down to Customer or Payment Data.

Next to some fields, there is a sign, which puts this field's data to the Blocklist.

After clicking on the sign, the data will be saved as a new Blocklist item in your Blocklist. It may take several minutes until you can see it in your Blocklist.
