Overview:
The Zip to Terr alignment fails with an error: field name:id value of incorrect type. The fields being copied contain valid data.
Root Cause:
If there are fields on the Account and Zip to Terr objects with the same API name, the process fails with this error.
Example: Having Zip_to_Terr_vod__c.Field_Name__C and Account.Field_Name__C in the same org causes the failure.
Solution:
Be sure that the API names of the fields being copied are unique to the org.
