I'm using DataLoader for the first time and I have successfully used "upsert" to create new accounts. But I can't really get my head around the following:
In my salesforce sandbox (which simulates a gas service company) each account has the following objects attached: Premise, Gas Service Point, Gas Meter and an Invoice. How do I make it so that all these objects are filled and linked using just one upsert. Is that possible?
I've tried adding all the information in a .csv file but in the dataloader I don't see the mappings that I need. So there's no link other than to the fields from the "Account" object.
I wish I could have tried more before coming here for help. But the truth is that I find the above process a little vague. So I am actually not sure where to even look for a possible solution.
Thanks in advance!
