Introduction
When configurating a dynamic list or loading a new file in a list, two import methods are possible:
- "replace" import
- "update" import
This choice defines how the import will impact the contact list.
"Update" import
This type of import applies when selecting 'Update existing contacts and add new ones'. It allows you to respond to a contact list feed with incremental files containing only movements since the last import.
The "update" import type performs the following processing:
- Creation of a contact if the primary key(s) combination does not exist in the contact list;
- Enrichment or modification of data if the contact present in the file already exists in the contact list;
- No processing on contacts present in the contact list and absent from the file.
