Scenario
The FullContact.txt file that contains your customer records contains duplicate
records. You must generate an output file that contains only the unique contact
records.
The output file containing only the unique records can then be used as the input
file to generate the label file.
Copying an Input Card to a New Map
Use the Map Designer to copy the input card from the ContactToFullLabel map
to an input card in a new map.
Copying a card automatically copies the input card and generates the new map at
the same time (if the destination map does not exist). The new map will be named
UniqueContacts.
To copy the input card to the input of a new map
1 Open the Mail.mms map source file.
2 Copy the ContactFile input card in the ContactToFullLabel map to a new
map named UniqueContacts.
This is the name of the map to which you want to copy the selected card.
Because there is no UniqueContacts map in Mail.mms, a new map by that
name will be created.
3 Enter ContactFile as the name of the new input card in the Name field.
