Import Erros

Hi All,

I am trying to import contacts for a marketing list using the "Connection" entity using "Connection From" "Connection To" fields. when i tried to import i am getting errors.

Error 1:

The lookup reference could not be resolved

Error 2:

The source data is not in the required format

The contacts are present in the CRM and are of same format. but still error is populating.

Any ideas?

Thanks,

Abhilash
