Load Account Data with a lookup to another Account record

[doudou23]

Hi,

I am struggling to load a CSV files on Account object while this account record refers to another account records. Let say my primary account records point to a field called AssociatedAccount__c. This account record has an externalId simply called ExternalID__c.

In my export I have tried to add AssociatedAccount__r.externalId and add the same and the corresponding value in my csv but after the load the link is never made. The tool doesn't complain about anything.

Does someone would have an example of export.json and account.csv that i could refer?

Many thanks, Grégory
