Address Attributes missing from Preferred Address after updating with AddressFinder
This is functioning properly. The Address Attribute stays with the address the attribute was originally assigned to.
If you chose to Save Old Addresses when Updating Data then it will be on the previous address found on the Address tab of the constituent record. From there, you can Globally Add the information as a Constituent Attribute or Solicit Code on the Constituent Record. This can be done based on queries, one for each Address Attribute that needs to be Globally Added as a Constituent Attribute or Solicit Code.
If you did not choose to save the old addresses then you can revert to a backup from before the Update Data was run and export out all of the Address Attributes and import them back in as Constituent Attributes or Solicit Codes.
