Add Contact
Add Contact can automatically create Contacts when importing Orders using a Service.
To start it is a checkbox on Folder Settings which download files for importing orders.
Validation 2
Validation 2 is a setting for Connect options or Services that download files to process. Validation 2 lets you test files before importing, to double-check, e.g. "customer=abc".
In Settings, in Validation 2, type an entry like "customer=abc" where customer is a key you want to check has an entry like "abc". This will block an error like a file for "xyz".
