+* Edit that journal and set a Txt map in **Statement Import Map** section in **Advanced

+
+* Now you can import Text based statements in that journal.
+
+Note: if existent Txt Map does not fit to your file to import, you can
+create another map in **Invoicing > Configuration > Accounting >
+Statement Import Map**.
+
+You can import headers from any Txt file in **Action > Create Map
+Lines** and set every line with which field of statement have to match.
