How can we upert to a Junction object using Apex Data Loader?
Junction object in the legacy system is a set of two foreign keys and they both together make up the primary key. How would I set up the external id in the salesforce and successfully use upsert functionality?
Hi, Experts - I got account and contact records into a sandbox and saved old ID values as in external / legacy fields for both objects. Question: using data loader how can I go about re-establish relations between account and contact utilizing external / legacy fields ? I did not want to work with csv files - thought data loader or any other API way I could do this ....help is appreciated, thank you.
