As you probably realize, changing field mapping can have unexpected results. If you change field mapping for data that’s already been synchronized, the next synchronization that occurs will be a first-run synchronization, which may cause duplicate records or record changes to occur in one or both of your systems. Back up data before changing field mapping. If possible, use a test file first to determine the results of the changed field mapping. It’s also a good idea to perform a synchronization before changing field mapping.

Here’s how to view or modify field mapping:

1. Click Advanced Settings.
2. Click Filters & Mapping.
3. Click Map Fields. The Field Mapping dialog box opens.
   • Yahoo fields appear in the left column.
   • Your desktop PIM application fields appear in the right column.
   • Mapped fields are indicated by an arrow in the center column.

To map or un-map fields, click the center column.

• Fields must be adjacent to map them. To make fields adjacent, click and drag the desktop PIM application field to the new location.
• Fields that must be mapped are indicated with an asterisk.
• To preserve data integrity, do not un-map time or date fields.
• Fields that contain different data types cannot be mapped to each other.

To restore default field mapping, click Reset.

Mapping special fields

• Fields that contain multiple lines: Different information can be stored on each line. If you don’t map each line, you can map extra lines to other fields.
• Other application fields that span more than one line of text: In some cases, you can map the field to two or more fields.

Note: Filtering on unmapped fields is not supported.
