    Accept the schema from tUniservRTMailBulk by clicking Yes on the prompt window.

  5. Connect the other components via Row > Main.

  6. Double-click tMap_1 to open the schema mapping window. On the left is the schema of the database file and on the right is the schema of tUniservRTMailBulk. At the bottom is displayed the Schema Editor, where you can find the attributes of the individual columns and edit them.

  7. Assign the columns of the input source to the respective columns of tUniservRTMailBulk. For this purpose, select a column of the input source and drag it onto the appropriate column on the right side.
